QUESTION # 135355

The pressure of gas is recorded as 1.0 x 105 N/m2 at a temperature of 0°C. The cylinder is heated further till the thermometer records 150°C. What is the pressure of the gas?

ANSWER

P₁V_I/T₁ =P₂V₂/T₂

Volume remains constant therefore

P₁/T₁ =P₂/T₂

P₁ =1.0× 10⁵ N/M²

T₁ = 0℃ = 0 + 273 =273K

P₂ =?

T₂ = 150 + 273 = 423K

1.0× 10⁵ N/M² ÷ 273K = P₂ ÷ 423K

P₂ = (1.0× 10⁵ N/M² × 423K) ÷ 273K

    =154945.0549 N/M²

    = 1.5×10⁵ N/M²
