If a hot cup of coffee is left on a table in a room that is 70 degrees, what would the final temperature be when heat stops transferring?

• The final temperature is 90° because there is more coffee than air.

• The final temperature is 70° because the air warms the coffee to the temperature of the air.

• The final temperature is between 90° and 70° because energy is transferred from the coffee to the air

• The final temperature is between 90° and 70° because most of the thermal energy is lost to the air around the substances

A glass of water is a room temperature in an isolated system.  What will happen if one ice cube is added to the system?

• Heat will be added to the system, causing the liquid water to increase in temperature but retain its state.

• Heat will be added to the system, causing the liquid water to increase in temperature and change state.

• Heat will be removed from the system, causing the liquid water to decrease in temperature and change its state.

• Heat will be removed from the system, causing the liquid water to decrease in temperature but retain its state.
