Example

How much heat is needed to raise 140 g of iron by 26 °C? (c = 0.45 J/g·°C)

Answer: 1638 J

RememberHeat energy

qmcΔTq = m × c × ΔTq = heat energy (J)c = specific heat (J/g°C)Water: c = 4.18 J/g°C
  1. 1

    How much heat is needed to raise 30 g of aluminum by 25 °C? (c = 0.9 J/g·°C)

    30 g aluminumq = ?c = 0.9 J/g°CΔT = 25 °Cq = m × c × ΔT
  2. 2

    7524 J of heat is added to 60 g of water (c = 4.18 J/g·°C). By how much does its temperature rise?

    60 g waterq = 7524 Jc = 4.18 J/g°CΔT = ?q = m × c × ΔT
  3. 3

    How much heat is needed to raise 110 g of water by 33 °C? (c = 4.18 J/g·°C)

    110 g waterq = ?c = 4.18 J/g°CΔT = 33 °Cq = m × c × ΔT
  4. 4

    19437 J of heat is added to 150 g of water (c = 4.18 J/g·°C). By how much does its temperature rise?

    150 g waterq = 19437 Jc = 4.18 J/g°CΔT = ?q = m × c × ΔT
  5. 5

    1528.8 J of heat is added to 140 g of copper (c = 0.39 J/g·°C). By how much does its temperature rise?

  6. 6

    How much heat is needed to raise 100 g of water by 15 °C? (c = 4.18 J/g·°C)

    100 g waterq = ?c = 4.18 J/g°CΔT = 15 °Cq = m × c × ΔT
  7. 7

    526.5 J of heat is added to 150 g of copper (c = 0.39 J/g·°C). By how much does its temperature rise?

  8. 8

    1827 J of heat is added to 70 g of aluminum (c = 0.9 J/g·°C). By how much does its temperature rise?

    70 g aluminumq = 1827 Jc = 0.9 J/g°CΔT = ?q = m × c × ΔT
  9. 9

    How much heat is needed to raise 50 g of water by 9 °C? (c = 4.18 J/g·°C)

    50 g waterq = ?c = 4.18 J/g°CΔT = 9 °Cq = m × c × ΔT
  10. 10

    1003.2 J of heat is added to 120 g of water (c = 4.18 J/g·°C). By how much does its temperature rise?

  11. 11

    How much heat is needed to raise 120 g of water by 6 °C? (c = 4.18 J/g·°C)

    120 g waterq = ?c = 4.18 J/g°CΔT = 6 °Cq = m × c × ΔT
  12. 12

    How much heat is needed to raise 200 g of aluminum by 9 °C? (c = 0.9 J/g·°C)

    200 g aluminumq = ?c = 0.9 J/g°CΔT = 9 °Cq = m × c × ΔT
