Question

if a gas at 300k occupies 3.60 liters at a pressure of 1.00 atm, what will be it’s new pressure if the volume is compressed to 2.0 liters at a temperature of 450K?

Answer 1

Answer: The new pressure if the volume is compressed to 2.0 liters at a temperature of 450K is 2.7 atm

Step-by-step explanation:

The combined gas equation is,

`(P_1V_1)/(T_1)=(P_2V_2)/(T_2)`

where,

`P_1` = initial pressure of gas = 1.00 atm

`P_2` = final pressure of gas = ?

`V_1` = initial volume of gas = 3.60 L

`V_2` = final volume of gas = 2.0 L

`T_1` = initial temperature of gas =
`300K`

`T_2` = final temperature of gas =
`450K`

Now put all the given values in the above equation, we get:

`(1.00* 3.60)/(300)=(P_2* 2.0)/(450)`

`P_2=2.7atm`

The new pressure is 2.7 atm
