  1. Calculating Heat Transfer q = m C ΔT

  2. q = m C ΔT • q = heat • m = mass • C = specific heat for that substance • ΔT = change in temperature Tf – Ti end temp – beginning temp

  3. Calculate the heat transfer. • A pot with 1500 mL of water at 15°C is heated over the flame until the temperature reaches 75°C. • Write the equation. • Fill in the numbers. • Calculate the answer and include units.

  4. Calculate the heat transfer. • A pot with 1500 mL of water at 15°C is heated over the flame until the temperature reaches 75°C. • q = m C ΔT • q = 1500 g (4.18 J/g°C) (75°C-15°C)

  5. Calculate the heat transfer. • If 6500 Joules of heat are added to 250 mL of water, how much will the temperature increase? • Write the equation. • Fill in the numbers. • Calculate the answer and include units.

  6. Calculate the heat transfer. • If 6500 Joules of heat are added to 250 mL of water, how much will the temperature increase? • q = m C ΔT • 6500J = 250 g (4.18 J/g°C) ( ? )
