Using first law of thermodynamics derive the relation between specific heat at constant pressure and constant volume.

Define first law of thermodynamics.

State first law of thermodynamics.

Write the relation between specific conductivity and cell constant of a solution.

The heat absorbed in a reaction at constant temperature and constant volume is

Write the relation between disintegration constant and half life.

An ideal gas undergoes a quasi-static, reversible process in which its molar heat capacity C remains constant. If during this process the relation of pressure p and volume V is given by pV^(n) = constant, then n is given by (Here C_(p) and C_(v) are molar specific heat at constant pressure and constant volume, respectively)

Show that the specific heat of a gas at constant pressure is greater than that at constant volume.

A gas of density 0.00125 g cdot cm^(3) , volume 8L at 0^(@)C temperature and 1 atm pressure is supplied with 30 cal of heat to raise its temperature to 15^(@)C at constant pressure. Determine the specific heat of the gas at constant pressure and at constant volume. Given, R = 2 cal cdot mol^(-1) cdot^(@)C^(-1) .
