📚 Part 1: Understanding Specific Heat Capacity

1. What is specific heat capacity?

How fast something moves

The amount of energy needed to raise 1 kg of a substance by 1°C

How heavy something is

The temperature of a material

2. Which unit is used for energy in the specific heat capacity formula?

Kilograms (kg)

Degrees Celsius (°C)

Joules (J)

Metres (m)

3. In the formula c = E/(m × Δθ), what does 'c' represent?

Energy

Mass

Temperature change

Specific heat capacity

4. What does Δθ (delta theta) mean in the formula?

Starting temperature

Final temperature

Temperature change

Room temperature

✏️ Part 2: Fill in the Blanks

Word Bank: energy, mass, temperature, joules, specific heat capacity, kilograms, temperature change, formula, Celsius

5. Complete the sentences using words from the word bank:

a) Specific heat capacity is the amount of _____________ required to raise the temperature of 1 _____________ of a substance by 1 degree _____________.

b) Energy is measured in _____________ and mass is measured in _____________.

c) The _____________ for specific heat capacity is c = E/(m × Δθ).

d) Δθ represents the _____________ in the substance.

🔢 Part 3: Simple Calculations

6. Use the formula c = E/(m × Δθ) to solve these problems. Show your working:

Example: E = 2000 J, m = 2 kg, Δθ = 5°C

c = 2000 ÷ (2 × 5) = 2000 ÷ 10 = 200 J/kg°C

Problem A: Calculate c when E = 1500 J, m = 3 kg, Δθ = 10°C

Problem B: Calculate E when c = 400 J/kg°C, m = 2 kg, Δθ = 8°C

Hint: Rearrange the formula to E = c × m × Δθ

7. Real-life application: A 0.5 kg block of metal needs 1200 J of energy to increase its temperature by 6°C. What is the specific heat capacity of the metal?
