A. Which of the following statements is true for a gas contained in a box with a piston?
1. Some but not all isothermal expansions are adiabatic.
2.An isothermal expansion is never adiabatic.
3.Every isothermal expansion is adiabatic.
4.Every expansion is either isothermal or adiabatic.
B. Doubling the gauge pressure of an ideal gas, while keeping the volume of the gas fixed, implies that the temperature changes how?
There is not enough information to solve this.
The temperature halves
The temperature doubles.
The temperature stays the same.
C. A pressure gauge measures the pressure of your bike tires by connecting to the inside of the tire via a small tube. The reading shows six atmospheres. If you were to replace that tube by another one that has twice the diameter of the original, what pressure would you read?
