Question

when the pressure that a gas exerts on a sealed container changes from ____ atm to 2.64 atm, the temperature changes from 315 K to 475 K

Answer 1

Answer:

1.75 atm

Explanation:

When the pressure that a gas exerts on a sealed container changes from 1.75 atm to 2.64 atm, the temperature changes from 315 K to 475 K.

(2.64 atm) x (315 K / 475 K) = 1.75 atm

The pressure and temperature of a gas in a sealed container are directly proportional. An increase in temperature would imply that the pressure also increased.

Answer 2

Answer:1.75 atm

Explanation:

In a closed system, increase in pressure leads to increase in temperature. Using pressure law, P1/T1 = P2/T2

Data =

P1 =?

P2 = 2.64 atm

T1 = 315k

T2 = 475k

From the equation above,

P1 = P2 * T1 / T2

P1 = 2.64*315 / 475

P2 = 1.75 atm
