a sample of helium gas occupies 14.3 L at 23 degrees C and 0.956 atm. What volume will it occupy at 40 degrees C and 1.20 atm

The volume will be 12.05 L

Explanation:

Boyle's law says that "The volume occupied by a certain gaseous mass at constant temperature is inversely proportional to pressure" and is expressed mathematically as:

P * V = k

Charles's law states that the volume of a gas is directly proportional to the temperature of the gas. That is, Charles's law is a law that says that when the amount of gas and pressure are kept constant, the ratio between the volume and the temperature will always have the same value:

Finally, Gay-Lussac's law states that at constant volume, the pressure of the gas is directly proportional to its temperature. This is expressed mathematically as:

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

Analyzing an initial state 1 and a final state 2, this law can be expressed as:

In this case:

Replacing:

Solving for V2:

V2= 12.05 L

The volume will be 12.05 L

i think a, hope it .

explanation:

a boiling water reactor does not boil the water. a pressurized water reactor boils the water faster. a pressurized water reactor is heated directly by the core. a pressurized water reactor does not use fission.
