An ideal gas initially at 30 K undergoes an isobaric expansion at 2.50 k Pa. If the volume increases from `1.00 m^(2)` to `3.00 m^(3)` and 12.5 kJ is transferred to the gas by heat, what are (a) the change in its internal energy and (b) its final temperature ?

(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 .

An ideal gas initially at pressure 1 bar is being compressed from 30m^(3) to 10m^(3) volume and its temperature decreases from 320 K to 280 K then find final pressure of gas.
