One mole of an ideal monatomic gas is heated at a constant pressure from 0^(@)C to 100^(@)C . Then the change in the internal energy of the gas is (given R = 8.32 J cdot mol cdot k^(-1))

A sample of ideal gas (gamma = 1.4) is heated at constant pressure. If an amount of 140 J of heat is supplied to the gas, find change in internal energy of the gas.

(i) 1 mol of an ideal gas expands isothermally and reversible from (P_(1)V_(1)T) to (P_(2)V_(2)T) . Write down the equation showinig the amount of heat absorbed by the given ideal gas. (ii) In an isothermal expansion of an ideal gas, the pressure of the gas decreases from P_(1) to P_(2) . write down the equation of work done by the gas in this process. (iii) The temperature of 1 mol of an ideal gas is increased from T_(1) and T_(2) . write down the equations for the changes in enthalpy and internal energy.

A gas absorbs 120J of heat and expands against the external pressure of 1.10 atm from a volume of 0.5 L to 2L what is the change in internal energy?(1 L atm=101.3J)

(i) The pressure and temperature of 0.8 g of He gas are 1 atm and 298 K respectively. If 400 J of heat is applied to the gas at constant volume, what will be change in internal energy and the final temperature of the gas ? (ii) If the same amount of heat is applied to the gas at constant pressure, then what will be the change in internal energy and the final temperature of the gas ? For both the cases, assume He gas behaves ideally and its C_(V)=(3)/(2)R .
