Students are given the assignment of improving a standard Styrofoam cup to create the best device to keep a cup of ice cold. They are allowed to use only the materials provided and are given a data table with each material’s specific heat.
Based on the descriptions, which student makes the best insulator?
Use air between an inner and outer Styrofoam cup because the specific heat is high (1005 J/Kg-oC) and will take a long time to transfer thermal energy.
Use water between two styrofoam cups because the specific heat is high (4182 J/Kg-oC) and will take a long time to transfer thermal energy.
Use a glass cup (753 J/Kg-oC) in addition to the styrofoam cup (1131 J/Kg-oC) to combine the two specific heats to slow the transfer of thermal energy.
Wrap the styrofoam cups in aluminum foil because the specific heat is low (897 J/Kg-oC) allowing the thermal energy to transfer quickly.

TRUE
FALSE.
A metal spoon was placed in a dish of hot soup and became warm. Which correctly describes the heat transfer process that resulted in the warming of the spoon?
Conduction, because the spoon was in contact with the hot soup.
Convection, because the spoon was in contact with the hot soup.
Conduction, because hot air currents affected the temperature of the spoon.
Convection, because hot air currents affected the temperature of the spoon.

When you boil water in a copper pot (with a specific heat of 385 J/kgoC) on the stove, which heats faster, the metal or the water (with a specific heat of 4182 J/kgoC)?
The water will heat faster because it requires more energy to heat it up due to the higher specific heat
The metal will heat slower because it requires more energy to heat it up due to the lower specific heat.
The metal will heat faster because it requires less energy to heat it up due to the lower specific heat.
The water and the metal will heat up at the same rate due to receiving the same amount of energy.

Why is it dangerous to leave an animal in a car with the windows closed in bright sunlight?
The air inside the car will absorb heat energy through conduction from the sun, increasing the temperature inside the car.
The air will become dangerously cold as heat energy is transferred out of the car by radiation.
The temperature inside the car will remain equal to the air temperature outside due to a state of equilibrium that could be dangerous.
The air inside the car will absorb and hold radiation the sun, increasing the temperature inside the car.
