Explanation:Please see attachment for explanation
The problem applies Charles' law since constant pressure with varying volume and temperature are given. Assuming ideal gas law, the equation to be used is

=

. We make sure the temperatures are expressed in Kelvin, hence the given added with 273. The volume 2 is equal to 25.2881 liters.
Answer:
yes its correct, temperature is a measure of energy particles have, the more energy the faster they move and the higher the temp
