Rest and motion relative

Answer» Ya..the statement is absolutely right and its a universal fact..an object can be in rest as well as in motion at an particular instant...it depends upon the reference point...e.g:-a man inside a moving bus is in rest in respect to another person inside that particular bus who is sitting but the same person is in motion with respect toa person outside the moving bus.

Explain why evaporation cause cooling??

Answer» Evaporation causes cooling because during evaporation the particle of the liquid absorbs energy from the surroundings to regain the energy lost during evaporation. the absorption of heat from the surrounding makes the surrounding cool. For Example, when we spray a deo on our hand,we feel a cooling sensation due to evaporation

Why is ice at 273K more effective in cooling than water at the same tempreature?

Answer» The temperature of 273K is equal to 0℃ and it is the melting point of ice ( to form water ) at the same temperature . Another point to be noted is thet the latent heat of melting of ice ( or fusion of ice ) is 3.34×10×10 ×10×10×10joules pee kg . Now ice at 273K 8s more effective in cooling a substance than water at the sane temperature of 273K because melting ,each kg of ice takes 3.34×10×10×10×10×10joules of its latent heat from the substance and hence cools the substance more effectively. On the other hand water at the same temperature of 273K cannot take away any such latent heat from the substance and hence does not cool it more effectively .

why sometimes temperature does not rise even when heat is supplied to a substance

Answer» Its the concept of latent heat
sometimes temperature does not rise when heat is supplied to the substance because the heat is absorbed by it to get converted into another state , this process is also known as the latent heat.
Because the heat supplied to a substance is used during the change of state in overcoming the intermolecular force
Because of latent heat .
Because this heat is used in breaking of intermolecular forces of attraction.

Why is ice at 273 K more effective in cooling than water at same temperature?

Answer» Ice at 273 K is more energetic than water. It is because of the difference in the latent heat of fusion which is present in the water at the same temperature in the form of extra energy.

Why do we see the droplets of water on the outer surface of cold surface. Of cold water gears

Answer» When water vapour in the air comes into contact with something cool, such as the outside of a cold glass of lemonade, its molecules slow down and get closer together. When that happens, the gaseous water vapor turns back into liquid water droplets. That\'s condensation!
