Temperature Scales

Define the term temperature.

Temperature is the measure of the mean translational kinetic energy of a body of particles.

True or False: The Kelvin Scale is based on water, so 0K is the freezing point and 100K is the boiling point.

False

Which of the following is not true about absolute zero:

a) It’s the lowest temperature on the Kelvin scale.

b) It’s when particles stop moving.

c) It’s the lowest temperature possible.

d) Lower temperatures are achieved in space.

d

True or False: A scientist invents a new temperature scale °X to solve a new problem in physics. In this scale −100°X is absolute zero and 100°X is the boiling point of water.

In this scale, 0°X is the melting point of water.

False

How can you convert from Celsius to Kelvin?

add 273.15

In the Fahrenheit scale, 32°F is the melting point of water and 212°F is the boiling point of water.

Which of the following statements is correct?

a) It takes more energy to heat water by 1°C than by 1°F.

b) It takes more energy to heat water by 1°F than by 1°C.

c) It takes the same amount of energy to heat water by 1°C as it does 1°F.

d) The energy to heat water in different temperature scales cannot be compared.

a

True or False: Instead of measuring temperature, an instrument is used to measure the average velocity of gas particles in two containers. It's found that the particles in container A are, on average, moving faster than the particles in container B.

The temperature of container A is greater than the temperature of container B.

True

An object has a temperature of 280.35 K.

What is its temperature in Celsius?

7.20°C

True or False: There is a point where the temperature in Kelvin is equal to the temperature in degrees Celsius.

False

-459.67°F
