In a mixture of gases, the pressure exerted by the individual gas is called

Options

A. total pressure
B. partial pressure
C. individual pressure
D. osmotic pressure

Answer

To solve the question, "In a mixture of gases, the pressure exerted by the individual gas is called," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Concept of Gas Mixtures**:
- In a mixture of gases, multiple gases are present, and each gas contributes to the total pressure of the mixture.

2. **Defining Individual Gas Pressure**:
- Each gas in the mixture exerts its own pressure, which is the pressure that it would exert if it occupied the entire volume alone at the same temperature.

3. **Introducing the Term 'Partial Pressure'**:
- The pressure exerted by an individual gas in a mixture is referred to as its "partial pressure."

4. **Mathematical Representation**:
- If we denote the partial pressures of gases A, B, and C as \( P_A \), \( P_B \), and \( P_C \) respectively, the total pressure \( P_{total} \) of the gas mixture can be expressed as:
\[ P_{total} = P_A + P_B + P_C \]

5. **Conclusion**:
- Therefore, the pressure exerted by the individual gas in a mixture is called "partial pressure."

### Final Answer:
The pressure exerted by the individual gas in a mixture of gases is called **partial pressure**.
