Example

At constant pressure, if a gas is heated, what happens to its volume?

Answer: it increases

RememberGas laws

Boyle: P₁V₁ = P₂V₂more pressure → less volumeCharles: V₁/T₁ = V₂/T₂hotter → bigger (T in K)Ideal: PV = nRTR = 0.0821 L·atm/(mol·K)
  1. 1

    A gas has a volume of 3 L at 200 K. At constant pressure it is heated to 300 K. What is its new volume?

    V₁ = 3 LT₁ = 200 KV₂ = ?T₂ = 300 K
  2. 2

    A gas has a volume of 9 L at 400 K. At constant pressure it is heated to 800 K. What is its new volume?

    V₁ = 9 LT₁ = 400 KV₂ = ?T₂ = 800 K
  3. 3

    A gas at 300 kPa has a volume of 10 L. At constant temperature, the pressure rises to 600 kPa. What is the new volume?

    P₁ = 300 kPaV₁ = 10 LP₂ = 600 kPaV₂ = ?
  4. 4

    A gas at 750 kPa has a volume of 3 L. At constant temperature, the volume grows to 9 L. What is the new pressure?

    P₁ = 750 kPaV₁ = 3 LP₂ = ?V₂ = 9 L
  5. 5

    A gas at 100 kPa has a volume of 2 L. At constant temperature, the volume grows to 4 L. What is the new pressure?

    P₁ = 100 kPaV₁ = 2 LP₂ = ?V₂ = 4 L
  6. 6

    A gas has a volume of 7 L at 250 K. At constant pressure it is heated to 375 K. What is its new volume?

    V₁ = 7 LT₁ = 250 KV₂ = ?T₂ = 375 K
  7. 7

    A gas has a volume of 9 L at 300 K. At constant pressure it is heated to 600 K. What is its new volume?

    V₁ = 9 LT₁ = 300 KV₂ = ?T₂ = 600 K
  8. 8

    A gas has a volume of 8 L at 250 K. At constant pressure it is heated to 500 K. What is its new volume?

    V₁ = 8 LT₁ = 250 KV₂ = ?T₂ = 500 K
  9. 9

    A gas at 200 kPa has a volume of 7 L. At constant temperature, the volume grows to 28 L. What is the new pressure?

    P₁ = 200 kPaV₁ = 7 LP₂ = ?V₂ = 28 L
  10. 10

    A gas has a volume of 3 L at 400 K. At constant pressure it is heated to 600 K. What is its new volume?

    V₁ = 3 LT₁ = 400 KV₂ = ?T₂ = 600 K
  11. 11

    A gas has a volume of 6 L at 250 K. At constant pressure it is heated to 375 K. What is its new volume?

    V₁ = 6 LT₁ = 250 KV₂ = ?T₂ = 375 K
  12. 12

    A gas at 900 kPa has a volume of 4 L. At constant temperature, the volume grows to 12 L. What is the new pressure?

    P₁ = 900 kPaV₁ = 4 LP₂ = ?V₂ = 12 L
