Question

Equal amount of heat are added to equal masses of aluminum and alcohol (ethyl) at the same initial temperature which substance will have the higher final temperature?

Expert Solution

Step 1

When heat is added to a substance, the transferred heat depends on three factors,

1 . temperature change

2. mass of the substance.

3. size and phase of the substance.

When heat is added to the substance its temperature increases.
Heat transfer is directly proportional to the mass of the system. If we require 1J of heat energy to increase 1⁰c of temperature with mass m, then we require 2J of heat energy to increase 1^o c of temperature with mass 2m.
