4. Two cups (A & B) with hot water are placed on the table side by side, which way will the heat flow when the substances have the same temperature?

5. Sophio Danielo places some room-temperature strawberries into his freezer. Which of the following correctly describes what happens to the strawberries?

Respuesta :

Answer:

1. C

2. D or C

3. B

4.  Heat will be transferred through molecular collisions from the hotter system to the cooler system.The thermal energy will flow in that direction until the two objects are at the same temperature.

5. The strawberries will start to get colder and freeze.  

Hope this helps

Answer:

1. - A

2. - D

3. - B

Explanation:

1. Answer:

A) the total amount of thermal energy

Reason:

Heat transfer is the flow of the heat, (meaning thermal energy) because of the temperature difference and the subsequent temperature distribution and changes. The study of the transport phenomena is defined by the exchange of momentum, energy, and mass in the form of conduction, convection, and radiation.

2. Answer:

D) The lid is used to reduce heat loss by convection

Reason:

The heat will not be able to move through the cup as well. This means that the heat will not be as strong because of the lid. Then we conclude that the lid is reducing the heat.

3. Answer:

B) from the boiling water to the aluminum cube

Reason:

The boiling water's heat will go through the aluminum cube. (I swear teacher's just add writing to confuse us humans.)

***4 and 5 are written by me however, I suggest you add onto it.***

4 Answer:

Even though both cups have the same substance temperature the heat will flow any where. This means that we would not be able to predict the heat flow. This also means that we would not be able to predict which way the heat would flow in order for both substances to have the same temperature.

5 Answer:

After Sophio places the room temperature strawberries in the fridge the temperature will rise. This is causes the surrounding frozen items thaw and refreeze which can alter the taste and texture of some foods. You would prevent this by placing the food in a shallow, wide container and refrigerate, uncovered, until cool.

I hope this helps! Sorry that I can't help any further!
