Question

Calculate the unknown quantity in each of the following measurements of gases.

P1 = 8.33 * 10^-4 atm
T1 = -84 degrees C
P2 = 3.92 * 10^-3 atm
T2 = ? degrees C

Answer 1

Gay Lussac' Law

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

T₁ = -84+273 = 189 K

8.33 x 10⁻⁴/189 = 3.92 x 10⁻3/T₂

T₂ = 889.411 = 616.411 °C
