Marie has a glass of water. The temperature of the water is 40°C. Then Marie adds some ice cubes to the water. After 10 minutes, what would the temperature of the water most likely be?
50°C
45°C
40°C
35°C
Lisa stirs some hot, apple cider with a metal spoon. Which sentence explains what happens to the spoon?
Heat from the hot liquid will warm the spoon until the spoon is hotter than the liquid.
Heat from the hot liquid will warm the spoon until they are both the same temperature.
Heat from the hot liquid will warm the spoon, but the liquid will remain hotter than the spoon.
Heat from the hot liquid will not have any effect on a metal spoon so the spoon will remain cool.
As Elba walks barefoot on the sand, her feet feel very hot. What is the reason for this?
Her feet have a higher temperature than the sand.
Her feet and the sand are the same temperature.
Heat is passing from her feet to the sand.
The sand is transferring heat to her feet.
Andrew observes the change of temperature of an object. Its temperature goes from 40°C to 20°C. What is Andrew’s most likely conclusion about the object?
It is losing energy as heat.
It is changing its color.
It is getting larger.
It is melting.
One form of energy is heat. Heat always flows between objects. What happens to the object into which the heat flows?
Its temperature falls.
Its temperature rises.
It changes from a gas into a liquid.
It changes from a liquid into a solid.
Energy can flow between objects as heat. Look closely at the picture. What is one way heat is flowing in the picture?
from the fire to the pot
from the person’s hand to the pot
from the person’s hand to the fire
from the water in the pot to the fire

Material 1
Material 2
Material 3
Material 4
Carmen wears wool socks with her winter boots to keep her feet warm. How is the wool important to heat flow?
Wool is an insulator that keeps Carmen’s feet from losing heat.
Wool is an insulator that provides heat to keep Carmen’s feet warm.
Wool is a conductor that transfers heat from Carmen’s feet to her boots.
Wool is a conductor that transfers heat from the socks to Carmen’s skin.
