A beach condo developer in Galveston is trying to decide what kind of windows to install in her condos. She wants the windows to provide the most comfortable environment for her renters. Which statement below is NOT a factor in choosing the windows?

• Windows that allow radiation from sunlight to warm the inside

• Windows that prevent outside air from entering via convection

• Windows that prevent inside air from escaping via convection

• Windows that block any thermal exchange

The table below lists the properties of the three types of energy transfer. Identify the type of energy transfer described in each column by matching each description to its type.

• Radiation

• Thermal energy transfers through a liquid or gas; Energy moves from hot, high energy to cool, low energy; Ex. Boiling rice

• Convection

• Thermal energy transfers through waves or rays; No matter is needed for thermal energy to travel; Ex. Energy from the Sun

• Conduction

• Thermal energy transfers through contact; Ex. Holding an ice pack to cool down your skin

The graph shows the thermal energy transfer in a liquid over time. Eventually, the energy transfer will enter equilibrium when the temperature stops decreasing and remains constant. At what time does the thermal energy transfer begin to slow down?

• 150 seconds

• 175 seconds

• 225 seconds

• 300 seconds

A student investigates the thermal energy transfer of two liquids. The student graphs the temperature of the liquids over time. Which statement best describes the thermal energy transfer of the liquids?

• Thermal energy from the cooler liquids is transferred to the warmer environment until the liquids reach thermal equilibrium.

• Thermal energy from the warmer liquids is transferred to the cooler environment until the liquids reach thermal equilibrium.

• Thermal energy from the environment is increasing the temperature of the liquids.

• Thermal energy from the warm liquids is decreasing the temperature of the environment.

The insulated tumbler shown in the image provided was designed to prevent thermal energy transfer. The tumbler comes in light colors for outdoor use, but this tumbler is dark-colored. It is constructed with a vacuum layer between the inner wall and the outer wall—there is no air between the two walls. How is the tumbler affected by the transfer of heat through conduction, convection, and radiation?

• Conduction and convection are reduced by the vacuum layer, while the dark exterior absorbs more radiation and can increase heat gain from sunlight.

• Conduction is increased by the vacuum layer, convection increases due to the air gap, and radiation is completely blocked.

• Conduction and convection occur easily through the air between the walls, and radiation is unaffected by the color of the tumbler.

• Conduction and convection are reduced by the vacuum layer, and the dark color reflects radiation to prevent heat gain.
