Energy and Waves Review

Your solar oven was the most efficient of the designs in class and your s'mores were ready much faster than any other group's. What design features helped transfer heat energy efficiently and directly to the grahams and marshmallows?

• The aluminum foil walls conducted heat energy toward the tin pan holding the s'mores. The tin pan radiated heat waves up towards the s'mores, causing them to absorb heat energy.

• The aluminum foil walls reflected incoming solar energy to the pan and the s'mores. The tin pie pan heated up quickly because it is metal and conducted heat energy to the grahams.

• The aluminum foil walls conducted heat energy toward the tin pan holding the s'mores. The tin pan, being metal and a good conductor, heated up quickly and melted the marshmallows.

• The aluminum foil walls reflected incoming solar energy to the s'mores and the tin pie pan. The tin pie pan, because it is metal, quickly reflected the heat energy to the s'mores.

If the temperature of a balloon were to decrease suddenly, the volume of the balloon would also decrease. What explains this phenomenon?

• Removing thermal energy decreases the kinetic energy of the gas molecules and the molecules move closer together, making the balloon smaller. 

• Removing thermal energy decreases the kinetic energy of the gas molecules and the molecules move farther aparat, making the balloon smaller.

• Removing thermal energy increases the kinetic energy of the gas molecules and the molecules move farther apart, making the balloon smaller. 

• Removing thermal energy increases the kinetic energy of the gas molecules and the molecules move closer together, making the balloon smaller.

You have been studying heat energy transfer in science class. Your task today is to design a solar oven to make s'mores: graham crackers, marshmallows, and melted chocolate. When you have successfully completed your oven, you can eat the s'mores. Your group has constructed the solar oven you see here. How is the solar energy transferred into the oven and directed to the s'mores on the pan?

• Solar energy is transferred via radiation.

• Solar energy is transferred via convection.

• Solar energy is transferred via conduction.

• Solar energy is transferred via reflection.
