`1 g` mole of an ideal gas at STP is subjected to a reversible adiabatic expansion to double its volume. Find the change in internal energy `( gamma = 1.4)`

One mole of an ideal gas at 25^(@)C is subjected to expand reversible ten times of its intial volume. The change in entropy of expansion is

During isothermal expansion of an ideal gas, the change in internal energy is ..............

One mole of an ideal monoatomic gas is taken at a temperature of 300 K . Its volume is doubled keeping its pressure constant. Find the change in internal energy.

One mole of a monoatomic ideal gas was isobarically heated from 300 K to 600 K at constant pressure of one atm. Subsequently, it is subjected to reversible adiabatic expansion till the volume becomes 4sqrt2 of origingl (starting) value. After that it is subjected to isobaric cooling to original volume.
