Question
**Problem Statement:**

Calculate the final pressure, in millimeters of mercury, for each of the following, if volume and amount of gas do not change:

**a.** A gas with an initial pressure of 1200 Torr at 155 °C is cooled to 0 °C.

**b.** A gas in an aerosol can at an initial pressure of 1.40 atm at 12 °C is heated to 35 °C.

**Instructions:**

- Use the ideal gas law where necessary.
- Consider using the equation \( P_1/T_1 = P_2/T_2 \), derived from the combined gas law, given constant volume and moles.
- Convert all temperatures from Celsius to Kelvin by adding 273.15.
- Convert all pressure measurements to the same unit when required.
