High specific heat means a material needed more energy to heat up. there are 2 objects started from the same temperature(25degree) and material a got to 73degrees c and material b got to 33 degrees c in the same amount of time. a had 48 degrees of temp. change and b had 8 degrees of temp change. which one has the highest specific heat?

The material B has the highest specific heat

Explanation:

Specific heat is defined as the amount of energy needed to increase by one degree the temperature of a unit mass of a certain substance.

Let's understand this problem better using numeric values and interpreting the results.

The amount of heat a body or substance receives is defined by the following expression:

If both bodies are receiving the same amount of heat Q = 15,000 [J], and both have the same mass, m=20[kg]

We will have:

In this way we can interpret that those materials with high specific heat value will require more energy to increase their temperature.
