# If the initial temperature of an ideal gas at 2.250 atm is 62.0 degrees C, what final temperature would cause the pressure to be reduced to 1.750 atm?

##### 1 Answer

The final temperature would be

#### Explanation:

This question is an example of Gay-Lussac's law relating temperature and pressure. This law states that the pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature. This means that if the pressure increases, the temperature also increases, and vice versa. The equation for this law is:

The temperature must be in Kelvins. To convert degrees Celsius to Kelvins, add

**Organize the data:**

**Known**

**Unknown**

**Solution**

Rearrange the equation to isolate

To convert Kelvins to degrees Celsius, subtract
