1. The gas in a used aerosol can is at a pressure 103 kPa at 25°C. If the can
is thrown into a fire, what will the pressure be when the temperature reaches
919°C?

412 kPa will the pressure be when the temperature reaches  to 919°C.

Explanation:

To calculate the final pressure of the system, we use the equation given by Gay-Lussac Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

where,

are the initial pressure and temperature of the gas in a used aerosol can.

are the final pressure and temperature of the gas in a used aerosol can.

We are given:

Putting values in above equation, we get:

412 kPa will the pressure be when the temperature reaches  to 919°C.

it is a solid

explanation:

it is stable as it is in group 0 which have full outer shells of electrons
