Reorder the following temperatures from highest to lowest:

• 400 ^oC

• 400 ^oC

• 440 ^oF

• -223 ^oC

• 0 K

​ (a)   measures the average kinetic energy of a sample of matter.

• Temperature
• Heat
• Absolute Zero

The ​ (a)   is a scientific theory that states that gases are composed of tiny particles that are in constant, continuous, random motion

• kinetic molecular theory
• absolute zero
• law of conservation of mass

The ​ (a)   temperature scale that sets its zero point at -273.15 degrees Celsius

• Kelvin
• Celsius
• Farhenheit
• Fahrenheit

The temperature at which a substance exists in both the liquid and solid forms is called the ​ (a)   .

• melting point
• boiling point
• proportionality constant

The temperature at which the liquid and gas phase of a single substance are in equilibrium is called the (a)   .

• boiling point
• melting point
• heat

According to the kinetic molecular theory of gases, which statement is NOT true for all gases?

• Gas particles are always moving.

• All particles in a gas move at the same speed.

• Gas particles do not collide with each other and with the walls of their container.

• Gas particles move randomly and in straight lines.

Below is a graph showing degrees Celsius versus degrees Fahrenheit. Is their relationship proportional?

• yes, because the graph is a straight line

• no, because the graph does not contain the point (0,0)

Which relationship explains how a thermometer works?

• As the temperature goes up, the volume of liquid inside the tube goes down.

• As the temperature goes down, the volume of liquid inside the tube stays the same.

• As the temperature goes up, the volume of liquid inside the tube goes up.

• As the temperature goes down, the volume of liquid inside the tube goes up.

When the temperature of a gas decreases, what happens to its density?

• increases, because the volume increases

• decreases, because the number of particles decreases

• decreases, because the number of particles decreases

• increases, because the volume decreases
