A student investigates the behavior of gas inside a sealed syringe.
When the plunger is pushed slowly into the syringe, the volume of the gas decreases and the pressure increases. The temperature of the gas remains constant. Explain in terms of particles why the pressure of the gas increases.
If the plunger is instead pushed very rapidly, work is done on the gas and its temperature increases. How does this increase in temperature affect the gas particles inside the syringe?
During a rapid compression, the energy transferred to the gas is 0.0162 J0.0162\text{ J}0.0162 J. The mass of the gas is 3.24×10−8 kg3.24 \times 10^{-8}\text{ kg}3.24×10−8 kg. The specific heat capacity of the gas is 1.00 kJ/kg ∘C1.00\text{ kJ/kg }^\circ\text{C}1.00 kJ/kg ∘C. Calculate the temperature change of the gas.
