Temperature and Heat

Question 96846 • 25-26 CHEMISTRY IN THE EARTH SYSTEM S1

Which factors are needed to determine the amount of heat absorbed by an aluminum cube after it is warmed? Check all that apply.final temperature of the cubeinitial temperature of the cubemass of the cubemelting point of aluminumspecific heat of aluminumvolume of the cube

Answer
A
final temperature of the cube
B
initial temperature of the cube
C
mass of the cube
D
melting point of aluminum
E
specific heat of aluminum
F
volume of the cube

Explanation

The heat absorbed is calculated with Q = mcΔT, where m is the cube’s mass, c is aluminum’s specific heat, and ΔT is the temperature change. The temperature change requires both the initial and final temperatures. The melting point and the cube’s volume are not needed for this calculation.
