If moon attract the earth why does the earth not move toward the moon |
| Answer» According to universal law of gravitation and Newton third law, we understand that the force of attraction between two objects is the same but it is applied in opposite directions. Thus the earth attracts the moon with the same force as the moon exerts on earth, but only in opposite directions.Since, earth is much larger in size than moon, so , the acceleration can not be noticed on earth surface. | |

Why is water called a universal solvent? ☺ |
| Answer» The major reason for which water is referred to as a universal solvent is because of its ability to dissolve many substances. The reason why water can dissolve many substances is because of its high polarity. The dielectric constant of water is 81 which is the highest for any solvent and hence it can dissolve many substances. Thus water molecules can easily break the bonds between the molecules of substance and therefore dissolve them. | |

Why Darwin is linked with natural system of classification |
| Answer» Natural system of classification is based on the basis of both external morphological character and internal features like anatomy, embryology, phytochemistry etc. Darwin also gave emphasis on surface features and correlations. Darwin suggested that surface features correlates underlying causes. Darwin also suggested embryology holds key in identifying species classification. This are the reasons why Darwin is linked with natural system of classification. | |

Example of thrust in daily life |
| Answer» Force exerted by an object perpendicular to the surface is called thrust.\xa0Camel can run easily over the sand: The feet of a camel are large. Larger feet mean larger area which results in low pressure. Due to this cam can easily walk on sand without sinking its feet.Tank easily can run over sand and mud: Caterpillar tracks; surrounding the wheels provide a larger surface area. Due to this, a tank can move on any terrain without sinking.Tractor has broader tyres: Tractors are made mainly for agriculture purpose. Because of broader tyres, a tractor exerts less pressure over the ground as pressure decreases with increase in surface area or contact and hence easily runs over the muddy field.One end of a nail is pointed: When a nail is pushed in a wall or wood, it is pushed from pointed side. Because of pointed shape, nail exerts more pressure over the wall or wood and is easily pushed by hammering. | |

What are the factors responsible for formation of soil? |
| Answer» \tThe Sun: The Sun heats up rocks during the day so that they expand. At night, these rocks cool down and contract. Since all parts of the rock do not expand and contract at the same rate, this results in the formation of cracks and ultimately the huge rocks break up into smaller pieces.\tWater: Water could get into the cracks in the rocks formed due to uneven heating by the Sun. If this water freezes, it would cause the cracks to widen.\tLiving organisms: The lichen when growing on the surface of rocks they release certain substances that cause the rock surface to powder down and form a thin layer of soil.\tRole of temperature: It is also play important role because fluctuations in temperature causes shrinking and swelling, frost action and general weathering in soils.\tTopography (Relief, Altitude and Slope): It is considered as passive factor to modifying the effects of climate because it affects soil processes, soil distribution and the type of vegetation. | |

What is grahm\'s law of diffusion? |
| Answer» Diffusion in the ability of a gas to spread and occupy the whole available volume irrespective of other gases present in the container.Thomas Graham in 1831 proposed the law of gaseous diffusion.The law states that under similar conditions of temperature and pressure, the rates of diffusion of gases are inversely proportional to the square roots of their densities.Mathematically Graham’s Law of Diffusion / Effusionr ∝ 1 / √dwhere r is the rate of diffusion and d is the density of the gas. | |

What is the structure of atoms? |
| Answer» Matters are made of tiny particles called atom. Atom is made of three particles; electron, proton and neutron. These particles are called fundamental particles of an atom or sub atomic particles.Electron (e– )- Electron is denoted by ‘e’ and is a negatively charged particle. The absolute charge over an electron is equal to 1.6x10-19 of negative charge and is considered equal to – 1.The relative mass of electron is 1/1836. Since the mass of an electron is very small, thus it is considered equal to 0. Electrons revolve round the nucleus of atoms.Proton (p+) - Proton is denoted by ‘p’ and is positively charged particle. The absolute charge over proton is 1.6x10 -19 coulomb of positive charge and it is considered as unit positive charge. Thus absolute charge over a proton is equal to +1.The absolute mass of a proton is equal to 1.6x10 -24 g and considered equal to 1 as it is equal to the mass of 1 hydrogen atom. Proton is present in the nucleus of atom.Neutron (n) – Neutron is denoted by ‘n’ and is a neutral particle. The absolute mass of neutron is 1.6 x 10 -24 g. The relative mass of neutron is equal to 1. Neutron is presents in the nucleus of atom. | |

Cell division in plants |
| Answer» Cell division is the process by which a parent cell divides into two or more cells called daughter cells. Cell division usually occurs as part of a larger cell cycle. All cells reproduce by dividing into two, with each parental cell giving rise to two daughter cells every time they divide. These newly formed daughter cells could themselves divide and grow, giving rise to a new cell population that is formed by the division and growth of a single parental cell and its descendant. In other words, such cycles of growth and division allow a single cell to form a structure consisting of millions of cells. | |

Similarity between boiling and evaporation |
| Answer» \timilarities between Evaporation and Boiling in terms of “ Transformation”Both represent the transformation from the liquid to the gaseous phaseStructures that are formed when a substance is in liquid phase are broken down during both processes, transforming it into the gaseous phase.\tSimilarities between Evaporation and Boiling in terms of “ Energy”Both require energy Usually thermal, but other forms of energy can also be used in order to increase the kinetic energy of the molecules, in order to make them evaporate or boil.\tSimilarities between Evaporation and Boiling in terms of “ External Conditions”Both depend on external conditions Both the rate of evaporation and the critical boiling temperature highly depend on the surrounding air pressure, humidity and temperature of both the air and liquid. | |

Explanation carbon cycle |
| Answer» Carbon enters life forms through the process of photosynthesis. Photosynthesis is the process by which plants prepare food in the presence of sunlight and chlorophyll. During photosynthesis, carbon dioxide and water combine to produce glucose and oxygen. This changes the atmospheric carbon into glucose molecules.\xa0Glucose, which is a source of food, is utilized by organisms to produce energy during respiration. During this process, glucose is broken down in the presence of oxygen to produce carbon dioxide.\xa0Thus, through the processes of photosynthesis and respiration, carbon is utilized and then returned to the environment.\xa0All organisms do not need oxygen to break down glucose and produce energy. The organisms which survive in the absence of oxygen are called anaerobes.\xa0Another process that releases carbon dioxide is called combustion. It is the process of burning. Many substances release carbon dioxide on burning. Vehicular emissions, industrial fumes, and the gases released during the process of cooking are some instances during which carbon dioxide is released.\xa0 | |
