The pressure measured by a constant volume gas thermometer is 40 kPa at the triple point of water. What will be the pressure measured at the boiling point of water `(100^@ C)`?

Explanation

To solve the problem, we need to find the pressure measured by a constant volume gas thermometer at the boiling point of water (100°C) given that the pressure at the triple point of water is 40 kPa.

### Step-by-Step Solution:

1. **Identify the Known Values:**
- Pressure at the triple point of water, \( P_t = 40 \, \text{kPa} \)
- Temperature at the triple point of water, \( T_t = 0^\circ C = 273.16 \, K \)
- Temperature at the boiling point of water, \( T_b = 100^\circ C = 373.16 \, K \)
