Question

A spray can is used until it is empty except for the propellant gas, which has a pressure of 1307 torr at 23°C. If the can is thrown into a fire (T = 477°C), what will be the pressure (in torr) in the hot can

Answer 1

`P_2=3312torr`

Step-by-step explanation:

Hello!

In this case, since here we have a pressure-temperature relationship, we need to use the Gay-Lussac's law in order to compute the final pressure as they are in a directly proportional relationship:

`(P_2)/(T_2) =(P_1)/(T_1)\\\\P_2= (P_1T_2)/(T_1)`

Now, we plug in the given pressure and temperatures in Kelvins to obtain:

`P_2= (1307torr*(477+273)K)/((23+273)K)\\\\P_2=3312torr`

Best regards!
