Question

A volume of 5.00 m3 of gas expands to a volume of 31.0 m3 while keeping the temperature a constant. What is the final pressure of the gas if the initial absolute pressure is 1.25 • 105 Pa?

Answer 1

Using Boyle's Law, we can determine the final pressure of the gas.

Step-by-step explanation:

In this problem, we can use Boyle's Law, which states that pressure and volume are inversely proportional as long as the temperature remains constant. The formula for Boyle's Law is:

P1 * V1 = P2 * V2

Plugging in the given values:

1.25 * 105 Pa * 5.00 m3 = P2 * 31.0 m3

Solving for P2:

P2 = (1.25 * 105 Pa * 5.00 m3) / 31.0 m3

Using the given values:

P2 = 2.0161 * 104 Pa

Therefore, the final pressure of the gas is approximately 2.02 * 104 Pa.
