Two metallic blocks P and Q having masses in ratio 2 : 1 are supplied with the same amount of heat. If their temperatures rise by same degree, compare their specific heat capacities.

Explanation

To solve the problem, we need to compare the specific heat capacities of two metallic blocks P and Q, given that their masses are in the ratio 2:1 and they are supplied with the same amount of heat, causing their temperatures to rise by the same degree.

### Step-by-Step Solution:

1. **Define the Masses**:
Let the mass of block P be \( m_P \) and the mass of block Q be \( m_Q \). According to the problem, the ratio of their masses is given as:
\[
\frac{m_P}{m_Q} = \frac{2}{1}
