# Is gas volume of 444 mL at 273K and 79.0 kPa. What is the final kelvin temperature when the volume of the gas is changed to 1880 mL and the pressure changed to 38.7 kPa?

##### 2 Answers

#### Answer:

#### Explanation:

We're asked to calculate the final absolute (Kelvin) temperature of a gas system when it is subdued to known pressure and volume changes.

To solve this problem, we can use the *combined gas law*:

For this equation to work, the units have to be *consistent*; for example, we can't plug in two values for pressure if one is measured in

Since all the units are consistent, here, solving the problem is straightforward enough: we simply plug in the known variables and solve the equation for the final temperature,

rounded to

Thus, the final Kelvin temperature after the changes in pressure and volume is

#### Answer:

The final temperature will be

#### Explanation:

This a question involving the Combined Gas Law. You can know that this involves the Combined Gas Law, because the variables are pressure, volume, and temperature, and they are the variables in the Combined Gas Law. The equation used to solve questions involving the Combined Gas Law is:
