  1. A 2 L balloon at 27 °C is warmed to 77 °C at constant pressure. What is its new volume, to 0.01 L, Bo?

  2. A 1.5 L balloon at 20 °C is warmed to 60 °C at constant pressure. What is its new volume, to 0.01 L, Esme?

  3. A pump's sealed cylinder holds 0.60 L of air at 100 kPa. Squeezed to 0.20 L at the same temperature, what is the pressure, Luz?

    • 33.3 kPa
    • 300 kPa
    • 100 kPa, as no air escapes

  4. Why does a sealed syringe get harder to push as the plunger goes in, Milo?

    • Smaller volume means higher pressure pushing back
    • The pressure falls as the volume falls, so it sticks
    • The air's temperature drops when squeezed

  5. A 2.0 L balloon at 300 K is cooled to 150 K at constant pressure. What is its new volume, Noah?

    • 4.0 L
    • 2.0 L, as nothing escapes
    • 1.0 L

  6. A balloon from a cool room is left in a warm car. Why does it get bigger, Pia?

    • Warmer gas takes up less space, so the rubber stretches
    • Warmer gas takes up more space at the same pressure
    • The car's air leaks into the balloon

  7. A 1.5 L balloon at 250 K warms to 300 K at constant pressure. What is its new volume, Ren?

    • 1.5 L, as nothing escapes
    • 1.25 L
    • 1.8 L

  8. A car tire's air is at 300 K and 330 kPa (absolute). On a hot day it reaches 330 K. What is the new pressure, Tala?

    • 363 kPa
    • 300 kPa
    • 330 kPa, as the tire is sealed

  9. Why do drivers check tire pressure before a long drive on a hot day, Zee?

    • Warmer air in the fixed tire volume raises the pressure
    • Heat lets air leak out through the rubber
    • Heat lowers the pressure, so the tire goes soft

  10. A sealed glass jar of air warms in the sun from 280 K to 350 K. By what factor does its pressure change, Ari?

    • Unchanged, since the jar is sealed
    • 1.25 times higher
    • 0.8 times, so lower
