You have a covered pot on a stove and you turn the heat on. If you assume that the pot and lid combination leaks, what can be said about the pressure, the volume and the amount of air within the pot on the stove after the heat is turned on compared to before the heat is turned on? Ignore changes in the size of the pot associated with the thermal expansion of the pot itself.
1.After the heat is turned on, the pressure within the pot is greater than it was before, the volume is the same, and the amount of air is less.
2.After the heat is turned on, the pressure within the pot is less than it was before, the volume is the same, and the amount of air is the same.
3.After the heat is turned on, the pressure within the pot is the same, the volume is the same, and the amount of air is less.
4.After the heat is turned on, the pressure within the pot is the same, the volume of air is less, and the amount of air is less.
Question 2
Which of the following could be associated with a temperature increase for a fixed amount of gas?
1.a decrease in the volume at constant pressure
2.a decrease in the pressure at constant volume
3.a decrease in both the pressure and the volume
4.an increase in the pressure at constant volume
