What is the difference between Kelvin and celcius |
|
Answer» The kelvin is the base unit of temperature in the International System of Units (SI), having the unit symbol K. The relation between kelvin and celsius scales is TK = t°C + 273.15. On the Kelvin scale, pure water freezes at 273.15 K, and it boils at 373.15 K.It is named after the Belfast-born Glasgow University engineer and physicist William Thomson, 1st Baron Kelvin (1824–1907). Celsius relates to, the Celsius temperature scale (previously known as the centigrade scale). The degree Celsius (symbol: °C) can refer to a specific temperature on the Celsius scale as well as serve as unit increment to indicate a temperature interval(a difference between two temperatures or an uncertainty). “Celsius” is named after the Swedish astronomer Anders Celsius (1701-1744), who developed a similar temperature scale two years before his death.K = °C + 273.15°C = K − 273.15Until 1954, 0 °C on the Celsius scale was defined as the melting point of ice and 100 °C was defined as the boiling point of water under a pressure of one standard atmosphere; this close equivalence is taught in schools today. However, the unit “degree Celsius” and the Celsius scale are currently, by international agreement, defined by two different points: absolute zero, and the triple point of specially prepared water. This definition also precisely relates the Celsius scale to the Kelvin scale, which is the SI base unit of temperature (symbol: K). Absolute zero—the temperature at which nothing could be colder and no heat energy remains in a substance—is defined as being precisely 0 K and −273.15 °C. The triple point of water is defined as being precisely 273.16 K and 0.01 °C. Celsius relates to, the Celsius temperature scale (previously known as the centigrade scale). The degree Celsius (symbol: °C) can refer to a specific temperature on the Celsius scale as well as serve as unit increment to indicate a temperature interval(a difference between two temperatures or an uncertainty). “Celsius” is named after the Swedish astronomer Anders Celsius (1701-1744), who developed a similar temperature scale two years before his death. |

?Difference between cell wall and plasma membrane? |
|
Answer» Cell wall is present in plants. Plasma membrane is present in animals .Cell wal has cellulose and plasma membrane don\'t have cellulose Cell wall is present only in plant cell for additional support as animals already have bones to protect themPlasma membrane is present in both Plant and Animal Cell for protecting materials not to enter into the cell but it will allow necessary things like water,oxygen etc Cell wall is present in plants. Plasma membrane is present in animals -Plasma membrane is semi permeable ..-Cell wall is entirely permeable ..-Plasma membrane is thin and visible only under an electron microscope ..-Cell wall is visible through a light microscope..-Plasma membrane is living and metabolicaly active.-cell wall is non living and inactive |

Write an essay on pollution urbanisayion |
| Answer» The days are gone when kids would roam freely on streets and birds would fly in the sky. Such a nice scene has been very rare to see, nowadays. We should blame ourselves only! India was a land of villages; our culture arose from villages only. But than we did something so bad that we are paying the price of it even today. We have replaced the major part of earth with factories, mills and building causing pollution.There are Various Levels at which Urban Pollution is happening like:Types and Causes of Urban Pollution\tAir Pollution:\xa0The air in the urban areas is always polluted with harmful substances and it is becoming hazardous day by day to breathe. The air in the cities is choking. The smoke from automobiles, factories and power generators make the air unhealthy. There are other factors also like chemical spills and other toxic gases that contaminate the air.\tWater Pollution:\xa0As it is there are very less natural water sources in the urban areas and the ones that are there are getting increasingly polluted. There is a lot of disposal in the lakes and rivers like household & industrial disposal. A lot of waste gets mixed with rain and washed into the waters.\tSoil Pollution:\xa0The mixing of toxins in the soil is disturbing the eco-system.\tNoise Pollution:\xa0Urban areas are one of the noisiest ones. Various sources of noise pollution include traffic noises, loud-speakers and other unwanted noises cause many health issues.\tRadioactive Pollution:\xa0The accidental leakage by nuclear power plants poses a big threat.\tVisual Pollution:\xa0The over exposure of visuals in the cities in the form of signs, billboards, screens, high intensity lights etc. are also quite disturbing.\tOther than these there is also ‘Thermal pollution’ that is caused by excessive amount of heat trapped in earth’s atmosphere. | |

Sir what is homogeneous mixture and hatrogenis |
|
Answer» Through combining two or more substances, a mixture is produced. A homogeneous solution tends to be identical, no matter how you sample it. Homogeneous mixtures are sources of water, saline solution, some alloys, and bitumen. Sand, oil and water, and chicken noodle soup are examples of heterogeneous mixtures. HOMOGENEOUS - the mixture which has uniform composition.example - suger+water , alcohol+water etc.HETEROGENEOUS - the mixture which has non-uniform composition.example - sand+water, water+oil etc. |

|
Answer» Through the SEMIPREMIABLE MEMBRANE by the process of diffusion By process of Diffusion The substances like CO2 and water move in and out of a cell by\xa0diffusion from the region of high concentration to low concentration. By the process of diffusion 1.Gases like CO2 moves in and out of the cell by diffusion in which it moves from the region of its higher concentration to the region of its lower concentration. 2. Water moves in and out of the cell by the process of osmosis.Osmosis is the movement of water from the region of its higher concentration to the region of its lower concentration when separated by a selectively permeable membrane. |
