(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Two 800 [tex]cm^{3}[/tex] containers hold identical amounts of a monatomic gas at 20 deg C. Container A is rigid. Container B has a 100 [tex]cm^{2}[/tex] piston with a mass of 10 kg that can slide up and down vertically without friction. Both containers are placed on identical heaters and heated for equal amounts of time.

What are the initial pressures in containers A and B?

The containers are not heated initially.

2. Relevant equations

To find the pressure of Container B we can use the equation [tex]P = \frac{F}{A}[/tex] where [tex]F = mg = 10 kg \times 9.8 \frac{m}{s^{2}}[/tex] and [tex]A = 100 cm^{2}[/tex]

3. The attempt at a solution

As I have found the Container B to be at 9800 Pascals (by converting cm to meters) I do not know how to approach the problem for finding the pressure for Container A.
