Question

A gas at constant volume has a pressure of 2. 80 atm at 400. K. What will be the pressure of the gas at 360. K? 2. 52 atm 2. 94 atm 3. 11 atm 3. 78 atm.

Answer 1

2.52atm for sure

Step-by-step explanation:

We know that:

P1= 2.80atm

T1= 400k

T2= 360k

And we want to find P2= ?

We have an equation: P1/T1 = P2/T2

Multiple both side by T2 to remove it

P2 = 2.52
