Question

1. Aerosol can carry warnings on their labels that say not to incinerate (burn) them or store

the cans above a certain temperature. The gas in a used aerosol can is at a pressure of
103 KPA at 25°C. If the can is thrown into a fire, what will the pressure be when the
temperature reaches 928°C?

Answer 1

3823.36 kPa will be the pressure be when the temperature reaches 928°C.

Step-by-step explanation:

Data given of aerosol can:

Gas stored at a temperature T1 = 25 °C

pressure of the gas = 103 kPa OR 1.01 atm

If can thrown in fire then temperature T2 = 928 ° C

final pressure when can thrown in fire, P2 =?

Gay Lussac Law is applied to know the final volume:

`(P1)/(T1)` =
`(P2)/(T2)`

rearranging the equation:

P2 =
`(P1T2)/(T1)`

putting the values in the equation:

P2 =
`(1.01 X 928)/(25)`

P2 = 37. 49 atm

The pressure will reach 37.49 atm or 3823.36 kPa is the pressure when it is thrown in the fire having temperature of 928 degree celsius.
