Question

How much heat is required to raise the temperature of a 175 g piece of aluminum from 37.0 oC to 92.0 oC?

Answer 1

2.07 × 10³ cal

Step-by-step explanation:

Step 1: Given and required data

• Initial temperature: 37.0 °C

• Final temperature: 92.0 °C

• Mass of aluminum: 175 g

• Specific heat capacity of aluminum (c): 0.215 cal/g.°C

Step 2: Calculate the change in the temperature experienced by the aluminum piece

ΔT = 92.0 °C - 37.0 °C = 55.0 °C

Step 3: Calculate the heat required (Q)

We will use the following expression.

Q = c × m × ΔT

Q = 0.215 cal/g.°C × 175 g × 55.0 °C

Q = 2.07 × 10³ cal
