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

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.
Which form of energy is almost always produced during energy transformations?
heat
light
electricity
sound
As water is heated, the motion of the water molecules will generally
decrease
increase
remain the same
The diagrams below represent the same two magnets placed in four different positions. The North (N) and South (S) poles are labeled.
At which position will the force of attraction between these two magnets be greatest?
The diagram below represents a weightlifter holding a barbell above his head.
The force of gravity pulling down on the barbell is 756 newtons (N). How many newtons of force are exerted by the weightlifter to hold the barbell up?
0 N
756 N
378 N
1512 N
Which force will decrease if the surface of the ramp is made smoother?
gravity
magnetism

A student added some sugar to a glass of water, but it did not dissolve quickly. What could the student do to increase the rate at which the sugar dissolves in the water?
freeze the water
heat the water
add salt to the water
filter the water
A substance in the solid phase (state) of matter has
a definite shape and a definite volume
a definite shape, but no definite volume
no definite shape, but a definite volume
no definite shape and no definite volume

If the temperature of the water in cup A continues to decrease as shown on the graph, what will the approximate temperature of the water in cup A be at the end of 25 minutes?
25°C
78°C
30°C
80°C
If the aluminum bar were shorter, the cool water in cup B would increase in temperature at a faster rate because
less heat would be produced by the water
less heat would be lost to the surrounding air
more heat would be produced by the water
more heat would be lost to the surrounding air
People often wear sunglasses in polar regions because most of the sunlight that strikes a snow-covered surface is
reflected
refracted
absorbed
transmitted
Which process transfers heat when particles collide in a solid?
convection
radiation
conduction
evaporation
In a car accident, a seat belt helps prevent injuries by applying a force
less than the force of the moving passenger
greater than the force of the moving car
in the same direction as the car’s motion
in the opposite direction of the passenger’s motion
