1. Specific Heat Calculations

2. What you need to know Heat Formula: Q = mcp∆t Q – heat transferred (J)
m- mass (g or kg)
Cp - specific heat capacity (J/g·C° or J/kg·C°)
∆t - temperature change (C°)

3. Question 1 Heat Formula: Q = mcp∆t
Specific heat capacity of water – J/g C0
Temperature change of the water – 10 C 0
Mass of water – 60 grams
Find the heat transferred - ?

4. Question 2 Heat Formula: Q = mcp∆t
A copper mass is placed in water and changes the water’s temperature from 60 0 C to 55 0 C. The water has a mass of 50 grams and a specific heat capacity of J/ g0 C
What was the amount of heat transferred from the water to the copper mass?

5. Question 3 Formula for specific heat: cp = Q/m∆t
Heat transferred – 30 Joules
Mass of substance – 100 grams
Change in temp C
Find the specific heat of this substance

6. Question 4
A substance with a mass of 10 grams is heated to C. The substance is placed in cold water and reaches equilibrium with the water at 50 0 C. The amount of heat transferred from the substance to the water is 500 Joules. Calculate the specific heat capacity of the substance
