When the temperature of the cylinder changes from 150K to 300K the pressure inside the cylinder doubles

Answer 1

Good morning. Assuming that all other factors remain constant, doubling the Kelvin temperature of a gas does indeed double the pressure.

We can verify this by setting up the equation shown below:

(P₁ / T₁) = (P₂ / T₂)

The problem does not provide us with any pressure values, so we may arbitrarily select a value for P₁. Let's say P₁ was 1.00 atm.

(1.00 atm / 150 K) = (P₂ / 300 K)

Clearly, P₂ must be 2.00 atm.
