Task Cards

One end of a metal rod is placed over a flame during an investigation. A thermometer is touching the opposite end of the metal rod. Which BEST describes what is happening during this investigation?

• Convection carries heat to the thermometer.

• Radiant energy warms the thermometer.

• Mechanical energy from the flame carries heat to the thermometer.

• Heat from the flame is conducted through the metal rod to the thermometer.

The transfer of heat in the atmosphere by winds that circulate between the equator and the poles is an example of

• radiation

• insulation

• convection

• conduction

A student filled a glass with warm water. She measured the temperature, and it was 30°C. She left the glass on a table in a room that was 20°C. A few hours later, she measured the water temperature again, and it was 24°C. Which BEST explains why the water temperature changed?

• Energy in the air removed heat from the water.

• Heat energy in the water was destroyed by the glass.

• Heat energy in the water was transferred to the cooler air.

• Energy used by evaporation caused the water temperature to decrease.

Why is covering up with a thick, fluffy blanket a good way to stay warm on a cold night?

• The blanket produces heat that warms your body.

• The blanket transfers thermal energy from the room to your body.

• The blanket decreases the transfer of thermal energy from your body to the air.

• The blanket increases the amount of thermal energy that your body produces.

A student bruised her knee. She applied an ice pack to the bruised area. When she removed the ice pack from the injured knee, she noticed that the temperature of her skin was lower than the rest of her body. What is the MOST likely reason this occurred?

• Increased blood flow due to the ice pack caused the skin to be cooler.

• The cooling energy of the ice pack was transferred to the skin.

• Heat energy from the skin was transferred to the ice pack.

• The air surrounding the ice pack cooled the skin.

Sunlight passes through the windows of a car and causes the car seats to get hot. Which type of energy flow is involved in heating the seats?

• conduction

• convection

• insulation

• radiation

Hot objects begin to cool as

• cooler air is transferred to the object.

• energy in the object is transferred to the surrounding air.

• atoms in the object react with the oxygen in the air.

• energy in the object cancel out energy in the air.
