A student grabs a skillet by the handle from the stove without gloves. What method of thermal energy transfer is the student experiencing?

• Convection

• Conduction

• Radiation

• Condensation

A boy sits in front of a campfire on a camping trip, warming his hands. Which best describes how most of the heat energy from the campfire reaches the boy?

• As the campfire warms the ground in front of the boy, the heat is conducted through his legs

• The heat from the fire produces convection currents through the open air and within the log her sits on

• As the fire burns, heat transfers to the boy's body through waves known as radiation

• The heat diffuses through layers of the atmosphere in alternating patterns until it reaches the boy's hands

Imagine that you live in a community where a company is proposing to build a hydroelectric power plant. Half of the community supports building the plant, and half is against the idea.

What is the best counter argument to "I support the hydroelectric plant because hydroelectric energy would help clean up the city's water source."

• I disagree because the hydroelectric plant will not provide the community with the number of needed water towers for each neighborhood.

• I disagree because the hydroelectric plant is an alternative energy source that is nonrenewable and scarce

• I disagree because the hydroelectric plant would most likely not help clean up the city's water source and this type of alternative energy causes a decrease in a town's population and an increase in wind erosion.

• I disagree because the hydroelectric plant would most likely not help clean up the city's water source, but this type of alternative energy causes less pollution and it renewable.
