true or false: changing the temperature of a substance does not depend on the material the substance is made out of.
true
false

Explanation:

First Question (Melting Ice Cube and Glacier)

To determine which object had more thermal energy added, we consider the concept of heat required for a phase change (melting). The amount of thermal energy needed to melt a substance depends on its mass (and the latent heat of fusion). A glacier has a much larger mass than a single ice cube. So, to melt the glacier, more thermal energy must be added compared to melting a single ice cube.

The change in temperature of a substance when heat is added or removed depends on its specific heat capacity, which is a property of the material (the substance it is made of). Different materials have different specific heat capacities. For example, water and metal have different specific heat capacities, so the temperature change for the same amount of heat added/removed will differ. Thus, changing the temperature of a substance does depend on the material it is made of, so the statement is false.

Answer:

the glacier
