Variables that are involved in the gas laws

par Leticia López

What is atmosferic preassure?

It is the force exerted on a surface by the air inside a balloon.

It is the force exerted on a surface by the air above it as gravity pulls it to Earth.

It is the force exerted on a surface by the mercury inside a balloon.

Which are the factors or variables that affect the pressure of a gas?

Amount of moles and volume

Temperature and amount of moles

Amount of moles, volume and temperature

What is the unit of temperature in which a gas should be measured?

Kelvin and Celsius

Celsius and Farenheit

Farenheit and Kelvin

Kelvin

Kelvin, Farenheit and Celsius

In Boyle's Law, what is the correlation between the variables?

The volume is inversely proportional to its pressure

The volume is directly proportional to its pressure

The pressure is inversely proportional to its temperature

The volume is directly proportional to the moles

Kelvin, Farenheit and Celsius

Pressure and volume

Volume and temperature

Temperature and moles

Kelvin, Farenheit and Celsius

In the Combined Gas Law, what is the factor that remains constant?

Volume

Pressure

Moles

Temperature

Kelvin, Farenheit and Celsius

Which of the following formulas is correct to express the Ideal Gas Law?

P1V1/T1 = P2V2/T2

P1V1 = P2V2

PV = nTR

V1/T1 = V2/T2

P1/T1 = P2/T2

Explanation

It is the force exerted on a surface by the air above it as gravity pulls it to Earth.

The pressure of a gas changes with the effect of temperature, volume and amount of moles of the gas

Gas temperature should always be measured in Kelvin

In Boyle's Law, the volume of a gas is inversely proportional to its pressure

In Gay-Lussac's law, pressure is directly proportional to temperature

In Charles Law, the factors that remain constant are the pressure and the number of moles

In the Combined Gas Law, the factor that remains constant is the amount of gas measured in number of moles

The Ideal Gas Law is expressed by the formula: PV = nTR
