Question

A gas at 89C occupies a volume of 0.67 L. At least what temperature will the volume increase to 1.12 L

Answer 1

At temperature 332.13 °C

Further explanation

Charles's Law stated that :

When the gas pressure is kept constant, the gas volume is proportional to the temperature

`\tt (V_1)/(T_1)=(V_2)/(T_2)`

T₁ = 89 °C=89+273=362 K

V₁ = 0.67 L

V₂ = 1.12 L

`\tt T_2=(V_2.T_1)/(V_1)\\\\T_2=(1.12* 362)/(0.67)=605.13~K=332.13~^oC`
