Pressure and Temperature of a Gas at Fixed Volume: Understanding the Relationship and Solving Calculations

The video tutorial explains the relationship between the pressure and temperature of a gas at a fixed volume, using the pressure law. It demonstrates how pressure and temperature are proportional and provides examples of calculating initial pressure and final temperature using the pressure law equation.

What happens to the pressure of a gas when its temperature increases at a fixed volume?

• The pressure decreases.

• The pressure fluctuates randomly.

• The pressure increases.

• The pressure remains constant.

What is the relationship between pressure and temperature for a gas at fixed volume?

• They are equal.

• They are unrelated.

• They are directly proportional.

• They are inversely proportional.

What does the pressure law equation P1/T1 = P2/T2 represent?

• The relationship between mass and volume.

• The relationship between initial and final pressures and temperatures.

• The relationship between pressure and volume.

• The relationship between volume and temperature.

In the pressure law equation, what units are used for measuring pressure?

• Newtons

• Watts

• Joules

• Pascals

If a gas has an initial temperature of 300 Kelvin and a final temperature of 400 Kelvin, what is the final pressure if the initial pressure is 305,000 Pascals?

• 140,000 Pascals

• 350,000 Pascals

• 305,000 Pascals

• Cannot be determined

How do you calculate the initial pressure of a gas using the pressure law?

• By multiplying the final pressure by the final temperature.

• By dividing the final pressure by the initial temperature.

• By adding the initial and final temperatures.

• By using the equation P1/T1 = P2/T2 and solving for P1.

What is the final temperature of a gas if its initial pressure is 370,000 Pascals and it is cooled to a pressure of 148,000 Pascals?

• 1000 Kelvin

• 3000 Kelvin

• 5000 Kelvin

• 2000 Kelvin
