Understanding Temperature Scales

What is temperature defined as in terms of particle motion?

• The gravitational force on particles

• The total mass of particles

• The average kinetic energy of particles

• The speed of light in a vacuum

Which temperature scale is most commonly used in chemistry?

• Fahrenheit

• Celsius

• Kelvin

• Rankine

At what temperature does water boil in Celsius?

• 212 degrees

• 0 degrees

• 32 degrees

• 100 degrees

What is the freezing point of water in Kelvin?

• 0 Kelvin

• 100 Kelvin

• 273 Kelvin

• 373 Kelvin

How do the increments of Celsius and Kelvin scales compare?

• Kelvin increments are larger

• Celsius increments are larger

• They have no relation

• They have identical increments

What is absolute zero in Celsius?

• 273 degrees

• -100 degrees

• -273 degrees

• 0 degrees

Why can't Kelvin temperatures be negative?

• Kelvin is only used in physics

• Kelvin is a man-made scale

• Kelvin measures absolute particle motion

• Kelvin is based on water's boiling point

How do you convert a Celsius temperature to Kelvin?

• Multiply by 2

• Add 273

• Subtract 273

• Add 100

What is the Kelvin equivalent of 25 degrees Celsius?

• 273 Kelvin

• 298 Kelvin

• 100 Kelvin

• 0 Kelvin

Why does Kelvin not use a degree symbol?

• Kelvin is not a real scale

• Kelvin is always positive

• Kelvin is based on water's freezing point

• Kelvin is used only in chemistry
