  1. A car tire's air is at 300 kPa (absolute) and 15 °C. After a hot-day drive it is 45 °C, same volume. What is the new pressure, to 0.1 kPa, Esme?

  2. A car tire's air is at 320 kPa (absolute) and 20 °C. After a hot-day drive it is 50 °C, same volume. What is the new pressure, to 0.1 kPa, Jun?

  3. Kira says a balloon at 20 °C doubles in volume when warmed to 40 °C. Which reply fits, Luz?

    • Agree: doubling the Celsius reading doubles the balloon's volume
    • Disagree: 293.15 K to 313.15 K is about 7% more
    • Agree, if the pressure stays fixed

  4. Luz says a cold car tire reads low because cold air leaks out. Which reply fits, Noah?

    • Disagree: colder air in a fixed volume has lower pressure
    • Agree: pressure rises in the cold, so the extra air must leak out
    • Agree: cold opens gaps in the rubber

  5. A sealed syringe is squeezed slowly so its temperature stays the same. Which law applies, Pia?

    • Charles's law, with the pressure held fixed as it is squeezed
    • Boyle's law, with temperature and amount fixed
    • Gay-Lussac's law, with volume fixed

  6. A balloon in the sun expands while the outside air keeps its pressure. Which law applies, Ren?

    • Gay-Lussac's law: pressure rises in a rigid box
    • Charles's law: volume rises with temperature
    • Boyle's law: volume rises as pressure rises

  7. A car tire's volume barely changes as it heats. Which law best fits its pressure rise, Tala?

    • Charles's law, with pressure fixed
    • Gay-Lussac's law, with volume nearly fixed
    • Boyle's law, with temperature fixed

  8. Plotting a gas's volume against kelvin temperature at fixed pressure gives what shape, Zee?

    • A straight line rising from the origin
    • A curve falling toward the axis
    • A flat, level line

  9. Plotting pressure against volume at fixed temperature gives what shape, Ari?

    • A flat, level line
    • A straight line rising from the origin
    • A curve that falls as volume grows

  10. What does P × V equal at each point on a Boyle's law curve, Bo?

    • The same value at each point
    • Zero at each point
    • A value that rises as the pressure rises

About this worksheet

Pressure, volume and temperature of a gas. Every version has 10 questions, and the answer key prints on the second page.

What your child will learn

  • I can use Boyle's law (P₁V₁ = P₂V₂) for a sealed syringe or pump at fixed temperature.
  • I can use Charles's law (V₁/T₁ = V₂/T₂) and Gay-Lussac's law (P₁/T₁ = P₂/T₂), with temperatures in kelvins.
  • I can name the law from what stays fixed, and describe each law's graph.

Standard: none (TX, FL)

Words to know

Boyle's law: P₁V₁ = P₂V₂ at fixed temperature

Charles's law: V₁/T₁ = V₂/T₂ at fixed pressure

Gay-Lussac's law: P₁/T₁ = P₂/T₂ at fixed volume

absolute pressure: Total pressure, not the gauge reading above the air's

Common mistakes

Your child had pressure and volume rise together. At fixed temperature, squeezing a gas raises its pressure: P₁V₁ = P₂V₂.

Your child had volume or pressure fall as the gas warmed. Warmer gas takes more space, or pushes harder, in kelvins.

Your child used Celsius in a gas law. The laws work in kelvins: add 273.15 first.

Questions parents ask

What is the most common mistake with pressure, volume and temperature of a gas?

Your child had pressure and volume rise together. At fixed temperature, squeezing a gas raises its pressure: P₁V₁ = P₂V₂.
