Density and pressure — practice question

A gas is trapped in a syringe, as illustrated. The gas starts with a volume of $2.00\text{ cm}^3$. The atmospheric pressure is $101\text{ kPa}$. When the gas is heated and expands to a volume of $6.00\text{ cm}^3$, what work does the gas do on the atmosphere?

  • A$404\,\mu\text{J}$
  • B$404\text{ mJ}$
  • C$404\text{ J}$
  • D$404\text{ kJ}$
