The diagram below represents the path of a ray of light as it passes from air into the water in a pond.

The change in the direction of the ray of light as it enters the water is called

• absorption

• refraction

• reflection

• transmission

The diagrams below represent four simple

machines. The arrows in each diagram indicate

the direction of the force being applied.

Which machine is changing the direction of the force being applied by the person?

• 
• 
• 
• 

Which graph best shows the general relationship between the temperature of a gas and the speed of the molecules in that gas

• 
• 
• 
• 

As a candle burns, the chemical energy stored in the wax is transformed into

• heat and light

• heat and magnetism

• electricity and light

• electricity and magnetism

Warm air rising in the atmosphere is an example of heat being transferred by

• absorption

• convection

• conduction

• radiation

The diagram below represents two cans of water at the same temperature. One can is painted black and the other can is painted white. The cans are placed on a sunny windowsill, and a thermometer is placed in each can to measure the water temperature.

After four hours in the sunlight, the temperatures of the water in the cans will most likely be

• the same as when the cans were placed there

• higher, with the same temperature in both cans

• higher in the white can than in the black can

• higher in the black can than in the white can

The diagram below represents a thermometer. Which principle best explains how this thermometer works?

• A liquid changes to a gas when heated.

• A gas changes to a liquid when heated.

• A liquid expands when heated and contracts when cooled.

• A liquid contracts when heated and expands when cooled.
