# A volume of 50.0 milliliters of an ideal gas at STP increases to 100 milliliters. If the pressure remains constant, what must the new temperature be?

##### 1 Answer

#### Answer:

The final temperature will be 500 K rounded to one significant figure.

#### Explanation:

This question involves **Charles' law** , which states that the volume of a given amount of gas varies directly with its temperature, as long as pressure and amount are kept constant. This means that if the volume increases, so does the temperature, and vice versa.
