One mole of an ideal monoatomic gas is heated in a constant pressure of one atmosphere from $0^\circ \,C$ to $100^\circ \,C$. Then the change in the internal energy is

$12.48 \times {10^2}{\rm{ joules}}$

$8.32 \times {10^2}{\rm{ joules}}$

One mole of an ideal monoatomic gas is heated in a constant pressure of one atmosphere from

0^\circ \,C

100^\circ \,C

. Then the change in the internal energy is

View answer and explanation

Correct option: C

12.48 \times {10^2}\mathrm{ joules}

The change in the internal energy is

12.48 \times {10^2}\mathrm{ joules}

because it is calculated using the formula

\Delta U = nC_v\Delta T

for a monoatomic gas.
