Heat System

Heat would best be transferred by conduction between

• a candle and the air.

• an oven and a glass dish.

• a stove and a copper pot.

• water and a wooden spoon

Sasha drops some of her ice cream sundae on a hot sidewalk. Which of the following correctly describes what happens next?

• The temperature of the sidewalk and the ice cream both remain unchanged.

• The temperature of the ice cream increases as it sends cold into the sidewalk.

• Heat from the sidewalk is transferred to the ice cream, increasing the temperature of the ice cream.

• Cold from the ice cream is transferred to the sidewalk, decreasing the temperature of the sidewalk.

Erin places some ice cubes into freshly made tea that is still quite warm. Which of the following correctly describes what happens to the ice cubes?

• Some of the heat from the tea is transferred to the ice cubes and causes them to melt.

• The temperature of the ice cubes remains the same as the temperature of the tea drops.

• The cold from the ice cubes is transferred into the tea and causes the cubes to warm up and melt.

• Heat is transferred between the ice cubes and the tea, which causes the temperature of the tea to increase.

On a particularly cold winter day, Kurt takes a plate of hot food outside to eat lunch. His mother calls him back inside and he forgets the plate outside. Which of the following will happen next?

• Cold from the air gets inside the food until the food is the same temperature as the air.

• Heat from the food transfers to the surrounding air until the food reaches the same temperature as the air.

• Cold from the air moves into the food until the temperature of the food drops below the temperature of the air.

• Heat from the food increases the temperature of the surrounding air until the air is the same temperature as the food.

Georgia places a pot of cold water on a hot stove. She accidentally turns the stove off. What will most likely happen after about 30 minutes?

• The temperature of the stove will decrease, but the temperature of the water will remain the same.

• The temperature of the water will continue to increase until some of it is changed to a gas and evaporates into the surrounding air.

• The temperature of the water will increase, and the temperature of the stove will decrease until they are both room temperature.

The temperature of a clay ball is 10ºF and the temperature of the water in a bucket is 30ºF.  A student places the clay ball into the bucket of water.  Which of the following describes how thermal energy is transferred between the ball and the water?

• Thermal energy is transferred from the ball to the water until they are both at 25ºF.

• Thermal energy is transferred from the water to the ball until they are both at 25ºF.

• Thermal energy is transferred from the water to the ball until the ball is at 30ºF and the water is at 10ºF.

• No thermal energy would be transferred between the ball and the water, so the ball will stay at 10ºF and the water will stay at 30ºF.
