Hola Senoritas y Senores,Please read each question carefully and remember that I can see your computer screen from my computer (Don't Diana your test). :) Good luck and do your best. Mr. Darnell

• 1.
Jorge's family has large dog that they feed outside.  During the winter Jorge is in charge of bringing in the water bowl any time that it is really cold.  One night he forgot to bring in the water bowl.How does the thermal energy of the freezing water change while the water is freezing?
• A.

The thermal energy stays the same.

• B.

The thermal energy increases.

• C.

The thermal energy decreases.

• D.

There is not enough information to answer the question

• 2.
Which of the following systems is a closed system for mass?
• A.

Your milk container at lunch that you opened to drink. The system is the milk container.

• B.

A pop can that you shake up without your friend knowing. The system is the pop can.

• C.

Some guy eating thirteen burritos. The system is the guy.

• D.

You playing basketball and sweating. You are the system.

• 3.
You put a can of pop in the freezer.  The freezer is closed.  What happens to the energy before the pop starts to freeze.
• A.

The pop (source) decreases in thermal energy and transfers heat energy tot the freezer (receiver), which increases in thermal energy.

• B.

The pop (source) decreases in thermal energy and transfers cold energy tot the freezer (receiver), which increases in thermal energy.

• C.

The freezer (source) decreases in thermal energy and transfers heat energy to the pop (receiver), which increases in thermal energy.

• D.

The freezer (source) decreases in thermal energy and transfers cold energy to the pop (receiver), which also decreases in thermal energy.

• 4.
Your car is able to drive all over D-town because it burns gasoline which gives motion (kinetic) energy to the engine parts.  The engine parts rub against each other and create a lot of heat through a friction interaction.  You want to find out if you can cook some food by wrapping it in foil and placing it under the hood of the car.  The food begins to cook.  Why is it cooking?
• A.

The food is undergoing a friction interaction which is causing it to increase in thermal energy.

• B.

The food is a warmer object near a cooler object and is cooking because of an infrared radiation interaction.

• C.

The food is a cooler object touching a warmer object and is cooking because it is increasing in thermal energy during a heat conduction interaction.

• D.

The food is a warmer object touching a cooler object and is cooking because it is increasing in thermal energy during a heat conduction interaction.

• 5.
LOOK AT THE GRAPH ON THE DOCUMENT CAMERA.What is happening to the oxygen during the time interval between (1) and (2)?
• A.

The temperature of gaseous oxygen is decreasing.

• B.

Gaseous oxygen is becoming a liquid.

• C.

The temperature of liquid oxygen is decreasing.

• D.

Liquid oxygen is becoming a solid.

• 6.

• A.

The temperature of gaseous oxygen is decreasing.

• B.

Gaseous oxygen is becoming a liquid.

• C.

The temperature of liquid oxygen is decreasing.

• D.

Liquid oxygen is becoming a solid.

• 7.
You have a glass of water that you filled up in the sink.  You set the glass on the table and leave it there for 15 minutes.  What happens to the stored phase energy of the water while it is sitting there?
• A.

The stored phase energy stays the same.

• B.

The stored phase energy increases.

• C.

The stored phase energy decreases.

• D.

There is not enough information to answer the question.

• 8.
You have some delicious horchata filled with ice on a hot summer day.  Describe the interaction while the ice is melting in the cup.
• A.

The overall temperature is decreasing as the liquid increases in thermal energy as the ice decreases in thermal energy during a heat conduction interaction.

• B.

The overall temperature is decreasing as the liquid increases in thermal energy as the ice decreases in thermal energy during an infrared radiation interaction.

• C.

The overall temperature stays the same as the liquid decreases in thermal energy as the ice increases in stored phase energy during a heat conduction interaction.

• D.

The overall temperature stays the same as the liquid decreases in thermal energy as the ice increases in stored phase energy during an infrared radiation interaction.
