On the basis of change of density with the change in temperature, explain how do the liquids get heated up, when heated in a vessel.

How does the density of gases change with the rise in temperature?

How does the density of a liquid change with the rise in its temperature?

In a p-n junction diode, change in temperature due to heating

In a p-n junction diode, change in temperature due to heating

Liquids can change into gas at any temperature when left in the open.

Solids can change into liquids on increasing the temperature.

Gibbs Helmholtz equation relates the enthalpy, entropy and free energy change of the process at constant pressure and temperature as DeltaG=DeltaH-TDeltaS " (at constant P, T)" In General the magnitude of DeltaH does not change much with the change in temperature but the terms TDeltaS changes appreciably. Hence in some process spontaneity is very much dependent on temperature and such processes are generally known as entropy driven process. When CaCO_(3) is heated to a high temperature it decomposes into CaO and CO_(2) , however it is quite stable at room temperature. It can be explained by the fact that

A substance on heating, undergoes (i) a rise in its temperature, (ii) a change in its phase without change in its temperature. In each case, state the change in energy of molecules of the substance.

During heat exchange, temperature of a solid mass does not change. In this process, heat

Change in state when enough heat is given to a solid.
