Question

A canister has a fixed volume. If the pressure of the cannister is 1.5 atm at 25 Celsius, what is the new pressure if the temperature rises to 75 degrees Celsius?

a) 4.5 atm
b) 1.6 atm
c) 1.3 atm
d) 1.8 atm

Answer 1

d) 1.8 atm

Step-by-step explanation:

According to Boyle's Law,

• P₁/T₁ = P₂/T₂

Here, we are given :

1. P₁ = 1.5 atm
2. T₁ = 25°C = 298 K
3. T₂ = 75°C = 348 K

Solving

• P₂ = P₁T₂/T₁
• P₂ = 1.5 x 348 / 298
• P₂ = 522/298
• P₂ = 1.8 atm (approximately)
