How much energy would it take to heat a section of the copper tubing that weighs about 535.0 g , from 15.29 ∘C to 21.30 ∘C ? Copper has a specific heat of 0.3850 (J/g)⋅∘C.

Respuesta :

Answer:

1238 J

Explanation:

Step 1: Given data

  • Mass of copper (m): 535.0 g
  • Specific heat of copper (c): 0.3850 J/g.°C
  • Initial temperature: 15.29°C
  • Final temperature: 21.30°C

Step 2: Calculate the change in the temperature

We will use the following expression.

ΔT = 21.30°C - 15.29°C = 6.01°C

Step 3: Calculate the energy required to heat the temperature of the copper tubing (Q)

We will use the following expression.

Q = c × m × ΔT

Q = 0.3850 J/g.°C × 535.0 g × 6.01°C

Q = 1238 J
