Give definition of movement.

Write the definition of chemical change?

Give the definition of electric potential.

Write down the equations relating pressure, volume and temperature for isothermal change and adiabatic change of an ideal gas.

Write the definition of physical change?

The initial state of 1 mol of an ideal gas is (P_(1),V_(1),T_(1)) . The gas is expanded by a reversible isothermal process and also by a reversible adiabatic process separately. If final volume of the gas is same in both the processes, and changes in internal energy in the isothermal and adiabatic processes are DeltaU_(1) and DeltaU_(2) respectively, then-

Given an example of a process which is simulataneously isothermal and adiabatic.

Give thermodynamic definition of heat and work.
