1

Argon gas is confined in a $3.0 \textup{ m}^3$ container at $310 \textup{ K}$ . What is the work done if the gas expands against an external pressure of $5.1 \textup{ kPa}$ to a volume of $3.5 \textup{ m}^3$ ? $1.0\textup{ Pa}\cdot \textup{m}^{3}=1.0 \textup{ J}$

Argon gas is confined in a $1.4\textup{ m}^3$ at $270 \textup{ K}$ . What is the work done if the gas expands against an external pressure of $3.2 \textup{ kPa}$ to a volume of $2.0 \textup{ m}^3$ ?

$1.0\textup{ Pa}\cdot \textup{m}^{3}=1.0 \textup{ J}$
