A1 mol sample of gas has a temperature of 225k, a volume of 3.3l, and a pressure of 500 torr. what would the temperature be if the amount of gas remains constant while pressure dropped to 210 torr, and the volume dropped to 2.75l?

78.75 K

We are given;

We are required to calculate the new temperature, T₂

P₁V₁/T₁ = P₂V₂/T₂

We can calculate the new temperature, T₂;

Rearranging the formula;

T₂ =(P₂V₂T₁) ÷ (P₁V₁)

  = (210 torr × 2.75 L × 225 K) ÷ (500 torr × 3.3 L)

  = 78.75 K

Therefore, the new volume of the sample is 78.75 K
