A sample of gas is found to occupy a volume of `900 cm^(-3)` at `27^(@)C`. Calculate the temperature at which it will occupy a volume of `300 cm^(3)`, provided the pressure is kept constant.

Explanation

To solve the problem, we will use Charles's Law, which states that for a given mass of gas at constant pressure, the volume of the gas is directly proportional to its temperature in Kelvin. The formula for Charles's Law is:

\[ \frac{V_1}{T_1} = \frac{V_2}{T_2} \]

### Step 1: Identify the given values
- Initial volume, \( V_1 = 900 \, \text{cm}^3 \)
