A sample of $CO_{2}$ has specific heat capacity of 630 J/kg °C at constant volume. If its temperature rises from 20°C to 45°C, what is the change in its internal energy per unit mass?

Options:

Answer:

Solution:

$Δ U = m S_{V} Δ T \Rightarrow \frac{Δ U}{m} = 630 \times 25 = 15750 J / kg = 15.75 kJ / kg$ .
