Q. If $R$ be the universal gas constant then, the amount of heat required to raise the temperature of $2$ mole of monoatomic gas under isobaric conditions from $0^{\circ}C$ to $100^{\circ}C$ will be :

Thermodynamics

Solution:

Given that $n =2$
$\Delta T =100$
$\Delta Q =n C_{p} \Delta T $
$\Delta Q =2 \times \frac{5}{2} R \times 100$
$\Delta Q =500\, R$
