Question

How much energy would it take to heat a section of the copper tubing that weighs about 665.0 g, from 15.71 ∘C to 27.09 ∘C ? Copper has a specific heat of 0.3850 (J/g)⋅∘C.

Answer 1

2914 J

Step-by-step explanation:

Step 1: Given data

• Mass of the copper tubing (m): 665.0 g

• Initial temperature: 15.71 °C

• Final temperature: 27.09 °C

• Specific heat of copper (c): 0.3850 J/g.°C

Step 2: Calculate the temperature change

ΔT = 27.09 °C - 15.71 °C = 11.38 °C

Step 3: Calculate the energy required (Q)

We will use the following expression.

Q = c × m × ΔT

Q = 0.3850 J/g.°C × 665.0 g × 11.38 °C

Q = 2914 J
