Consider a gas at 1.00 atm in a 5.00-L container at 20.0 °C. What pressure does the gas exert when transferred to a volume of 2.00 L at 43 °C?

The pressure is 2.696 atm

Explanation:

Boyle's law relates pressure and volume inversely proportionally and is expressed mathematically as:

P * V = k

Charles's law consists of the relationship between the volume and temperature of a certain amount of ideal gas, which is maintained at a constant pressure, by means of a proportionality constant that is applied directly and is expressed mathematically as follows:

Gay-Lussac's law indicates that the gas pressure is directly proportional to its temperature and is expressed mathematically as:

Combined law equation is the combination of three gas laws called Boyle's, Charlie's and Gay-Lusac's law:

When you want to study two different states, an initial and a final one of a gas, you have the expression:

In this case, you know:

Replacing:

Solving:

P2= 2.696 atm

The pressure is 2.696 atm

the product of the pressure and volume is also constant
