Answer : The new absolute pressure is, 
Explanation :
Gay-Lussac's Law : It is defined as the pressure of the gas is directly proportional to the temperature of the gas at constant volume and number of moles.

or,

where,
= initial pressure of gas
= final pressure of gas
= initial temperature of gas = 
= final temperature of gas = 
Now put all the given values in the above equation, we get:



Therefore, the new absolute pressure is, 
Answer:
<h2>The answer is 1.5 L</h2>
Explanation:
The new volume can be found by using the formula for Boyle's law which is

Since we are finding the new volume

From the question we have

We have the final answer as
<h3>1.5 L</h3>
Hope this helps you
This change in pressure is caused by changes in air density, and air density is related to temperature. Warm air is less dense than cooler air because the gas molecules in warm air have a greater velocity and are farther apart than in cooler air.
Hydrogen has the lowest density.
