Temperature Scales and Gas Laws

The video tutorial covers the concept of a constant volume gas thermometer, explaining how pressure and temperature are related in a constant volume system. It discusses the concept of absolute zero and different temperature scales, including Celsius, Kelvin, and Fahrenheit. The tutorial also covers temperature conversion and relative changes in temperature, and concludes with a comparison of temperatures of different materials.

What is the primary function of a constant volume gas thermometer?

• To calculate the density of a gas

• To measure pressure changes at constant volume

• To maintain a constant temperature

• To measure the volume of a gas

What happens to the pressure of a gas in a constant volume gas thermometer when it is placed in boiling water?

• The pressure remains constant

• The pressure decreases

• The pressure increases

• The pressure becomes zero

At what temperature do all gases extrapolate to zero pressure according to the constant volume gas thermometer?

• 273.15 degrees Celsius

• -273.15 degrees Celsius

• 100 degrees Celsius

• 0 degrees Celsius

What is the lowest temperature achieved experimentally in Kelvin?

• 10^-9 Kelvin

• 10 Kelvin

• 1 Kelvin

How is the Celsius temperature related to the absolute temperature?

• Celsius temperature is equal to absolute temperature times 273.15

• Celsius temperature is equal to absolute temperature minus 273.15

• Celsius temperature is equal to absolute temperature plus 273.15

• Celsius temperature is equal to absolute temperature divided by 273.15

How do you convert a Celsius temperature to Fahrenheit?

• Multiply by 5 and divide by 9

• Multiply by 1.8 and add 32

• Multiply by 9 and divide by 5

• Add 273.15

If the Celsius temperature increases by 5 degrees, how much does the Kelvin temperature increase?

• 1 degree

• 0 degrees

• Ice cube at -20°C and flames at 233°C

• Water at 0°C and steam at 100°C

• Boiling water at 100°C and glass of water at 50°C

What is the Kelvin temperature of an ice cube at -20°C?

• 273 Kelvin
