Answer:
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:
[tex]Q=m*c_{p}*(t_{f}-t_{i} ) \\where:\\m=mass[kg]\\c_{p}= specific heat [\frac{J}{kg*C} ][/tex]
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:
[tex]Material A\\15000=20*C_{p} *(73-25)\\C_{p}=\frac{15000}{(20*48)} \\C_{p}=15.6[\frac{J}{kg*C} ]\\\\Material B\\15000=20*C_{p} *(33-25)\\C_{p}=\frac{15000}{(20*(8))} \\C_{p}=93.8[\frac{J}{kg*C} ][/tex]
In this way we can interpret that those materials with high specific heat value will require more energy to increase their temperature.
