Start on Your Calculator
Use a TI-84 Plus CE or CE Python with the bundle programs installed. Start in the CHEM launcher:
CHEM → Thermo/Gases → Gas Laws
For Problems 1–6, choose Ideal Gas Law and the quantity you need to find. For Problems 7–8, choose Boyle’s Law and the required unknown.
For ideal-gas calculations, enter volume in liters and temperature in kelvin. Choose R to match the pressure units: 1 = atm, 2 = kPa, 3 = mmHg. The Boyle’s law routines do not ask you to choose R.
