Question

when the pressure that a gas exerts on a sealed container changes from blank torr to 900 torr the temperature changes from 300 k to 450 k

Answer 1

It's 600 torr, just use Gay-Lussac's law P1/T1=P2/T2

Answer 2

Initial pressure = 600 torr

Step-by-step explanation:

Given:

Initial pressure, P1 = 900 torr

Initial Temperature, T1 = 300 K

Final temperature, T2 = 450 K

To determine:

Final pressure of gas, P2

Step-by-step explanation:

Based on the ideal gas equation

`PV = nRT\\`

where n = moles of gas

R = gas constant, T = temperature

At constant volume (V), the above equation becomes:

P/T = constant

This is Gay-Lussac's law

`(P1)/(T1) =(P2)/(T2) \\\\P1=(P2)/(T2) *T1=(900\ torr)/(450\ K) *300\ K=600\ torr`
