A 1.00 L volume of gas at 35.0 °C exerts a pressure of 85.5 kPa. What will the pressure

be at 127 °C? Assume constant volume.​


Sagot :

Answer:

111.03kPa = P₂

Explanation:

Gay Lussac's Law states that the pressure of a gas is directly proportional to the absolute temperature when volume remains constant.

The equation is:

P₁T₂ = P₂T₁

Where P is pressure and T absolute temperature of 1, initial state and 2, final state of the gas.

P₁ = 85.5kPa

T₂ = 127°C + 273.15 = 400.15K

P₂ = ?

T₁ = 35°C + 273.15 = 308.15K

P₁T₂ = P₂T₁

85.5kPa*400.15K = P₂*308.15K

111.03kPa = P₂
