Which of these energy transfers occurs in a solar panel?

• Mechanical energy is transferred to the panel when waves from the sun push against the panel and move it.
• Electromagnetic energy is transferred to the panel when light waves from the sun are absorbed by the panel.
• Thermal energy is transferred to the panel when it is connected with an electrical source in a complete circuit.
• Electrical energy is transferred to the panel when it is connected with an electrical source in a complete circuit.

The picture shows a hurricane over the ocean. Which statement best describes the energy flow in the formation of a hurricane?

• Energy is released as water freezes and absorbed as clouds condense.
• The sun’s energy is absorbed as water evaporates and released as it falls as rain.
• Energy is released as clouds condense and absorbed as rain falls to cause a hurricane.
• The sun’s energy is absorbed as water evaporates and released as it condenses into hurricane clouds.

A glass of ice water is shown below before and after it reaches room temperature. Which statement explains something that occurred in the time between these two images?

• As water vapor condensed on the glass, it absorbed energy.
• The ice cubes expanded in volume as they melted into liquid water.
• The water droplets outside the glass absorbed energy as they evaporated.
• Some liquid water inside the glass sublimated into water vapor in the air.

Tai grows plants in a container called a terrarium, as shown. He keeps the terrarium on a sunny windowsill. The terrarium is completely closed, so Tai cannot add water to the plants. However, the plants have enough water to grow. Which statement best explains why the plants always have enough water?

• The air cannot hold all of the water vapor.
• Water is unable to evaporate from the soil.
• The plants take up water and store it in their stems and leaves.
• Energy from the sun cycles water through the soil, the plants, and the air.
