A given amount of gas A is confined in a chamber of constant volume. When the chamber is immersed in a bath of melting ice, the pressure of the gas is 100 cm Hg.
What is the temperature when the pressure is 10 cm Hg ?

Explanation

To solve the problem step by step, we will use the ideal gas law, which states that for a given amount of gas at constant volume, the pressure of the gas is directly proportional to its temperature in Kelvin.

### Step-by-Step Solution:

1. **Identify Given Values:**
- Initial Pressure (P1) = 100 cm Hg
- Initial Temperature (T1) = 273 K (temperature of melting ice)
- Final Pressure (P2) = 10 cm Hg
