Question

Without completing the calculations, determine what the new pressure will be in the problem below. Also,

explain how you were able to determine the new pressure without completing the calculations. Pay special
attention to how the temperature is changing in the problem.
A sample of ozone (0:2) is stored at x kelvin and 12.5 Pa. If the temperature is doubled to 2x kelvin,
what will the new
pressure be?

Answer 1

The new pressure will be doubled

Further explanation

Given

A sample of ozone (O₃) at x K and 12.5 Pa. (T₁= x K, P₁=12.5 Pa)

the temperature is doubled to 2x K (T₂=2x)

Required

the new pressure

Solution

Gay Lussac's Law

When the volume is not changed, the gas pressure is proportional to its absolute temperature

`\tt (P_1)/(T_1)=(P_2)/(T_2)`

Input the value :

`\tt (12.5)/(x)=(P_2)/(2x)\\\\P_2=(12.5* 2x)/(x)`
