Example

How much heat is needed to raise 110 g of water by 20 °C? (c = 4.18 J/g·°C)

Answer: 9196 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

    312 J of heat is added to 200 g of copper (c = 0.39 J/g·°C). By how much does its temperature rise?

    200 g copperq = 312 Jc = 0.39 J/g°CΔT = ?q = m × c × ΔT
  2. 2

    1453.5 J of heat is added to 170 g of iron (c = 0.45 J/g·°C). By how much does its temperature rise?

  3. 3

    342 J of heat is added to 10 g of aluminum (c = 0.9 J/g·°C). By how much does its temperature rise?

    10 g aluminumq = 342 Jc = 0.9 J/g°CΔT = ?q = m × c × ΔT
  4. 4

    15048 J of heat is added to 120 g of water (c = 4.18 J/g·°C). By how much does its temperature rise?

    120 g waterq = 15048 Jc = 4.18 J/g°CΔT = ?q = m × c × ΔT
  5. 5

    6897 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 = 6897 Jc = 4.18 J/g°CΔT = ?q = m × c × ΔT
  6. 6

    How much heat is needed to raise 40 g of aluminum by 28 °C? (c = 0.9 J/g·°C)

    40 g aluminumq = ?c = 0.9 J/g°CΔT = 28 °Cq = m × c × ΔT
  7. 7

    1980 J of heat is added to 110 g of iron (c = 0.45 J/g·°C). By how much does its temperature rise?

    110 g ironq = 1980 Jc = 0.45 J/g°CΔT = ?q = m × c × ΔT
  8. 8

    5852 J of heat is added to 50 g of water (c = 4.18 J/g·°C). By how much does its temperature rise?

    50 g waterq = 5852 Jc = 4.18 J/g°CΔT = ?q = m × c × ΔT
  9. 9

    How much heat is needed to raise 80 g of copper by 20 °C? (c = 0.39 J/g·°C)

    80 g copperq = ?c = 0.39 J/g°CΔT = 20 °Cq = m × c × ΔT
  10. 10

    How much heat is needed to raise 10 g of water by 16 °C? (c = 4.18 J/g·°C)

    10 g waterq = ?c = 4.18 J/g°CΔT = 16 °Cq = m × c × ΔT
  11. 11

    How much heat is needed to raise 70 g of iron by 31 °C? (c = 0.45 J/g·°C)

    70 g ironq = ?c = 0.45 J/g°CΔT = 31 °Cq = m × c × ΔT
  12. 12

    436.8 J of heat is added to 160 g of copper (c = 0.39 J/g·°C). By how much does its temperature rise?
