Latent heat is evolved during the transformation of liquids into solids." How will you explain this statement?
When latent heat of phase transformation from solid to gaseous state is studied for ice, for temperature range of 20 °C to 80 °C, graph of temperature versus time is
In temperature range of o "C to 4 °C, at ......... volume of water is maximum due to expansion.
If objects of equal masses are given equal heat, their final temperature will be different. This is due to difference in their ............ .
The air is said to be unsaturated if vapour contained in a given volume of air at a temperature
When the air contains maximum possible water vapour, it is said to be ................. with vapour at that temperature.
In the experiment to study the effect of heat on ice, what will be the maximum rise in temperature of water?
The amount of heat energy to be supplied to convert 2 kg of ice at 0°C completely into water at 0 °C if latent heat of fusion for ice is 80 cal/g is........ .
With increased height from sea level, melting point of solids which expand on solidifying .......... .
The increase in temperature of water above its boiling point in the pressure cooker is due to change in .............. .
When ice of 0 °C is heated to convert into steam, for what values of temperature thermometer dipped into ice shows constant reading for some time?
Tiny drops on window pane of car at dawn in winter indicates ............... temperature is attained.
The amount of heat necessary to raise the temperature of 1 g of water by 1 °C from 14.5 °C to 15.5 °C is called
If two ice cubes are pressed against each other. they stick together firmly after some time because ............. .
