The Pressure Readings of Butane and Propane Tanks
Which statement is true regarding the pressure readings of the butane and propane tanks?
A. The pressure reading for the butane tank is higher than that for the propane tank
B. The pressure readings will change when more liquid is added to the tanks
C. If the tanks are placed outside and warmed by the sun, the pressure readings will be higher than they were initially
D. The temperature of the butane tank will be lower than that of the propane tank
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.
In this scenario, the pressure reading for the butane tank is actually 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. Since propane has more gas molecules than butane, it will exert a higher pressure.
Furthermore, 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. Therefore, adding more liquid will not affect the pressure unless it evaporates and increases the amount of gas.
Lastly, if the tanks are placed outside and warmed by the sun, the pressure readings will indeed be higher than they were initially. This is because as the temperature increases, the gas molecules inside the tanks gain more kinetic energy and move faster, resulting in increased pressure.
Overall, the temperature of the butane tank is actually lower than that of the propane tank due to the average kinetic energy of the gas molecules, not the number of moles. Therefore, the statements provided can be classified accordingly based on the properties of butane and propane.
