Luke is about to start cooking. He places some butter in a pan and heats up the pan. As the pan heats up, the butter begins to melt.  How is the heat energy  moving?

• The cold is moving from the pan and into the butter

• The heat is moving from the pan and into the butter

• The cold is moving from the butter and into the pan

• The heat is moving from the butter and into the pan

Four containers made of different materials, each containing water at 30º C, were set out on a table. The initial temperature of the water was recorded.    The temperature of the water was also recorded 15 minutes later.   Which container was the most effective at preventing heat transfer from the water to the environment?

• Container P

• Container Q

• Container R

• Container S

A beaker with water is placed on a hot plate to increase the temperature of the water.    What forms of energy transfer occur while the hot plate is turned on?

• Radiation occurs where the hot plate touches the beaker. Convection occurs in the movement of the water.

• Conduction occurs where the hot plate touches the beaker. Radiation occurs in the movement of the water.

• Convection occurs where the hot plate touches the beaker. Conduction occurs in the movement of the water.

• Conduction occurs where the hot plate touches the beaker. Convection occurs in the movement of the water.

A 120° piece of iron was added to a beaker of 10°C water.  The temperature of the water was measured as time passed. After 9 minutes, the water temperature stopped increasing and stayed at 23°C. What would the temperature of the block be when the water temperature stabilized (stopped changing)?

• 10°

• 120°

• 23°

• 65°
