Change in internal PE of a substance .............(change its state/ change its temperature).

Statement-1: The internal energy of a system does not change when there is not change in temperature Statement-2: The internal energy of a gaseous system is state function.

Connectrations are expressed in terms of ...... And .... Which does not change with temperature.

A zone of gradual change in temperature of a lake is

Sublimation is a change in a substance from .............. state to...... State.

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.

The rate of a reaction quadruples when the temperature changes from 293K to 313K . Calculate the energy of activation of the reaction assuming that it does not change with temperature.

The rate of a reaction increases four times when the temperature changes from 300 K to 320 K. Calculate the energy of activation of the reaction, assuming that it does not change with temperature. (R = 8.314 JK^(-1) mol^(-1) )
