Question

A 295 g aluminum engine part at an initial temperature of 13.00 °C absorbs 75.0 kJ of heat. What is the final temperature of the part (c = 0.9J / g * K)

Answer 1

To calculate the final temperature of the aluminum engine part, you can use the equation Q = mcΔT, where Q is the heat absorbed, m is the mass of the aluminum part, c is the specific heat capacity of aluminum, and ΔT is the change in temperature. The final temperature is 299.3°C.

Step-by-step explanation:

To calculate the final temperature of the aluminum engine part, we can use the equation Q = mcΔT, where Q is the heat absorbed, m is the mass of the aluminum part, c is the specific heat capacity of aluminum, and ΔT is the change in temperature.

First, we need to convert the mass of the aluminum part from grams to kilograms: 295 g = 0.295 kg.

Next, we can rearrange the equation to solve for ΔT: ΔT = Q / (mc).

Plugging in the values, we get: ΔT = (75.0 kJ) / ((0.295 kg)(0.9 J/g°C)).

Calculating this, the final temperature of the aluminum part is 299.3°C.
