The density of water at $$4^{\circ}C$$ is $$1000\:kg\:m^{-3}$$ and at $$104^{\circ}C$$ it is $$958.4\:kg\:m^{-3}$$. The cubic expansivity of water between these temperature is

Two containers A and B contain liquid at 50C. Two metal balls one at 50C and the other at 30C are dropped in the containers A and B respectively. In which container will the transfer of heat take place?

A glass of cold water whose particles had a low average kinetic energy was placed on a table. The average kinetic energy in the cold water increased, while the average kinetic energy of the part of the table under the glass decreased. What do you think happened?

In the diagram shown, will the convection current be clockwise or anticlockwise on the left part of the figure?

When the specific heat of a solid is measured  by the method of mixture, the heat is lost to surroundings from the calorimeter by the process of

The amount of heat required to raise the temperature of 100g of copper (sp. heat = 390 J/kg$$^o$$ C) from $$40^o$$ to $$90^o$$ is

Thermal energy is always transferred from .............. to ............. temperatures

A ........... is a device used to measure heat

When you heat a bowl of water, we can observe that water starts circulating. This demonstrates:

A gas behaves more closely like an ideal gas at
