A $26$ cm $-$diameter vertical cylinder is sealed at the top of a frictionless $21$ kg piston. The piston is $83$ cm above the bottom when the gas temperature is $311$ degC $.$ The air above the piston is at $1$ atm $.$

Part A

What is the gas pressure inside the cylinder?

Express your answer with the appropriate units.

$p_0=$

$$

Part B

What will the height of the piston be if the temperature is lowered to $16$ degC? Enter your answer in CENTIMETERS, such as $"41$ cm $".$ For some reason if you use meters the problem only accepts the answer SOMETIMES.

Express your answer with the appropriate units.
