Question

152 dm^3 of gas has a pressure of 98.6 kpa. at what pressure will the volume be quartered

Answer 1

Answer:

P₂ = 394.4 KPa

Explanation:

Given data:

Volume of gas = 152 dm³

Pressure of gas = 98.6 KPa

Final pressure = ?

Final volume = quartered = 1/4×152 = 38 dm³

Solution:

P₁V₁ = P₂V₂

P₂ = P₁V₁/V₂

P₂ = 98.6 KPa .  152 dm³ / 38 dm³

P₂ = 14987.2 KPa.  dm³ / 38 dm³

P₂ = 394.4 KPa
