Final answer:
The pressure reading for the butane tank is lower than that for the propane tank. The pressure readings will not change when more liquid is added to the tanks. The pressure readings will be higher than they were initially when the tanks are warmed by the sun.
Step-by-step explanation:
The statements can be classified as follows:
- False: The pressure reading for the butane tank is lower than that for the propane tank. This is because the pressure of a gas depends on the number of gas molecules and their kinetic energy. Propane has more gas molecules than butane, so it will exert a higher pressure.
- False: The pressure readings will not change when more liquid is added to the tanks. The pressure inside the tanks is determined by the temperature and the amount of gas present, not the amount of liquid. Adding more liquid will not change the pressure unless it evaporates and increases the amount of gas.
- True: If the tanks are placed outside and warmed by the sun, the pressure readings will be higher than they were initially. As the temperature increases, the gas molecules inside the tanks gain more kinetic energy and move faster, resulting in increased pressure.
- False: If an equal number of moles of gas escape rapidly from each tank, the temperature of the butane tank will be the same as that of the propane tank. The temperature of a gas only depends on the average kinetic energy of its molecules, regardless of the number of moles.
