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

2.07 × 10³ cal

Explanation:

Step 1: Given and required data

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

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence

frequency, z, and the collision density, z, in carbon dioxide (co2), r 180 pm at 30 °c and 120 kpa
