The pressure of the gas in a constant volume gas thermometer is 70 kPa at the ice point. Find the pressure at the steam point.

Explanation

To solve the problem, we will use the relationship between the pressure of a gas at two different temperatures in a constant volume gas thermometer. The steps are as follows:

### Step-by-Step Solution:

1. **Identify the Given Data:**
- Pressure at the ice point (P_ice) = 70 kPa
- Temperature at the ice point (T_ice) = 0°C = 273 K
- Temperature at the steam point (T_steam) = 100°C = 373 K
