Question

When the pressure changes from 1.21 atm to 2.52 atm, the volume changes from 3.75 L to 1.72 L and the temperature changes from 293 K to _ k

Answer 1

280 K

Step-by-step explanation:

Answer 2

Answer is 280 K

Step-by-step explanation:

Let's assume that the gas is an ideal gas.

Then we can use combined gas law,

PV/T = k (constant)

Where, P is the pressure of the gas, V is volume of the gas and T is the temperature of the gas in Kelvin.

For two situations, we can use

P₁V₁/T₁= P₂V₂/T₂

P₁ = 1.21 atm

V₁ = 3.75 L

T₁ = 293 K

P₂ = 2.52 atm

V₂ = 1.72 L

T₂ = ?

From substitution,

1.21 atm x 3.75 L / 293 K = 2.52 atm x 1.72 L / T₂

T₂ = (2.52 atm x 1.72 L x 293 K) / (1.21 atm x 3.75 L)

T₂ = 279.9 K

T₂ = 280 K
