Question

In an industrial process, the temperature of a fixed amount of gas in a rigid container drops from 50 degrees Celsius to 25 degrees Celsius. What will be the final pressure in the container if the initial pressure is 3.6 atmospheres?

1.8 atm

3.3 atm

3.9 atm

7.2 atm

Answer 1

Convert temperatures from Celsius to Kelvin
50 degrees Celsius = 323 Kelvin
25 degrees Celsius = 298 Kelvin
3.6 * (298/323) = 3.32 atmospheres
