A typical refrigerator is kept at 4˚C, and a soda can has a pressure of

1.18 atm. The inside of a car can reach up to 60˚C (140˚F) when it is left in

direct sunlight on a hot day. If you left the soda can in the car, what would

be the new pressure if it reached 60˚C?

The new pressure will be 1.42 atm

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.

are the final pressure and temperature of the gas.

We are given:

Putting values in above equation, we get:

Hence, the new pressure will be 1.42 atm
