Answer» 2. Copper sulphate can be obtained from an impure sample by crystallisation. The impurities will remain in the mother liquor whereas the pure copper sulphate will crystallize out.3. Because they dont have mass , neither they occupy space nor they are made up of particles or atoms... as in the definition of matter.. Sound an light are not considered as matter because matter is anything which have weight an occupies space and sound and light are not made up of molecules.4. The boiling point of water in Celsius scale is 100 DEGREE celsius and on Kelvin scale it is 373 K!5. All CELLS are surrounded by a plasma membrane. The membrane is composed of a phospholipid bilayer arranged back-to-back. The membrane is also covered in places with cholesterol molecules and proteins. The plasma membrane is selectively permeable and regulates which molecules are allowed to enter and exit the cell.6. The SMALLEST cell is the sperm cell and the largest cell is ovum in the human body. The sperm is a male reproductive cell and they are small in size. The sperm cell head measures about 4 mm in length, just slightly smaller than a red blood cell. The ovum also called egg cell is the reproductive cell in the female body.7. Osmosis is the spontaneous net movement of solvent molecules through a selectively permeable membrane into a region of higher solute concentration, in the direction that tends to EQUALIZE the solute concentrations on the two sides.8. Velocity is a physical quantity that gives both the speed and direction of motion of the body. Defintion: Velocity of a body is defined as the displacement produced per unit time.9. When the body moves with a uniform velocity i.e., it does not change its speed or direction over the travel, the relation of distance and time is proportional, that is distance travelled remains proportional with the time.10. The 'acceleration of a body' moving with uniform velocity will be zero as acceleration is defined as the “rate of change of velocity” per unit time. So if the body EXHIBIT uniform velocity, then the rate of 'change of velocity' (dv = 0) will be zero.I Hope This Will Help You❤️❤️❤️❤️❤️ |

Write the applications of pressure in solids and liquids |
|
Answer» e is the force per unit area. The SI Unit of Pressure is the pascal (Pa). A pascal can be defined as a force of ONE NEWTON applied over a surface area of one meter square. In other forms,Pressure = Force / AreaThe pressure is dependent on the area over which the force is acting, WITHOUT any CHANGE in the force, the pressure can be INCREASED and decreased. The Force applied to be constant if the surface becomes smaller the pressure increases and vice versa. |
