A constant volume gas thermometer using helium records a pressure of 20.0k Pa at the triple point of water, and a pressure of 14.3 k Pa at the temperature of 'dry ice' ( solid `CO_(2)` ) . What is the temperature of dry ice?

Explanation

To solve the problem of finding the temperature of dry ice using the given pressures from a constant volume gas thermometer, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the relationship between pressure and temperature**:
Since the gas thermometer operates at constant volume, we can use the formula:
\[
\frac{P_1}{T_1} = \frac{P_2}{T_2}
