Question

4. By what quantity must the heat capacity be divided to obtain the specific heat of that material? (I poin

Answer 1

Answer:

its mass

its temperature

Explanation:

The heat capacity of a body is the amount of heat needed to raise that temperature of a body by 1k or 1°C.

It is expresses as:

              H = m c Ф

where m is the mass of the body

           c is the specific heat of the body

           Ф is the temperature change of the body

Specific heat capacity is that heat content needed to raise the temperature of a unit mass of a substance by 1k or 1°C

Heat capacity is also known as heat content;

 To solve the problem:

 since H = m c Ф

  we make the unknown c the subject of the expression;

                c = $\frac{H}{m (t_{2} - t_{1} )}$ = H / mФ

So to obtain the specific heat capacity, divided the heat capacity by mass and its temperature change.
