Heat Capacity vs Specific Heat Capacity - Class 10 Physics

1. What is the relationship between heat capacity (C) and specific heat capacity (c)?

C = c × Volume
C = c × Mass
C = c / Mass
C = c + Mass

Correct Answer: C = c × Mass

2. Which of the following statements is true about specific heat capacity?

It is the heat required to raise the temperature of 1 kg of substance by 1°C.
It is the total heat required to heat an object.
It depends only on the volume of the object.
It is expressed in Newtons.

Correct Answer: It is the heat required to raise the temperature of 1 kg of substance by 1°C.

3. Which of the following is true about heat capacity?

It is a constant value for all substances.
It depends only on the type of material.
It depends on both mass and specific heat capacity of the substance.
It is measured in Pascals.

Correct Answer: It depends on both mass and specific heat capacity of the substance.

4. What is the SI unit of specific heat capacity?

J/kg°C
J/Kg
N/m²
Watt

Correct Answer: J/kg°C

5. If the specific heat capacity of iron is 450 J/kg°C and the mass is 10 kg, what is its heat capacity?

4500 J/°C
45 J/°C
4.5 J/°C
45000 J/°C

Correct Answer: 4500 J/°C
