Answer 1

Answer these with VERY VERY short and simple sentences please

What is convection?


What type of matter does convection occur within?


Explain how convection works when you boil water on a stove. Feel free to draw/add a diagram to support your answer.



What is density?


Is warm air or cold air more dense and why?


What is a convection current?


Hot air or water
Falls
Rises
Stays in place

What is conduction?


Explain one example of conduction that you have experienced in the last week.


What is radiation?


Give two examples of radiation.

Answer 2

Here's the completed chart for the phase changes regarding kinetic energy and potential energy:

| State of Matter | Kinetic Energy | Potential Energy |
|--------------------|----------------|-------------------|
| Liquid to Gas | Increase | Increase |
| Liquid to Solid | Decrease | Decrease |
| Solid to Liquid | Increase | Decrease |
| Solid to Gas | Increase | Increase |
| Gas to Liquid | Decrease | Decrease |
| Gas to Solid | Decrease | Increase |

### Explanations:
1. **Liquid to Gas:** Kinetic energy increases because the molecules move faster, and potential energy also increases as the molecules spread apart.
2. **Liquid to Solid:** Kinetic energy decreases as the molecules slow down, and potential energy decreases as the molecules come closer together.
3. **Solid to Liquid:** Kinetic energy increases as heat is added, causing molecules to move more freely, while potential energy decreases as the molecules are moving closer together.
4. **Solid to Gas:** Kinetic energy increases significantly as the molecules gain energy and move apart, and potential energy also increases due to increased separation.
5. **Gas to Liquid:** Kinetic energy decreases as gas cools and molecules lose energy, and potential energy decreases as they come closer together.
6. **Gas to Solid:** Kinetic energy decreases significantly as particles lose energy and come close to each other, while potential energy increases as the structure becomes more ordered.

Feel free to ask any follow-up questions or for further clarifications!

Answer 3

Sure! Here are the answers in very short and simple sentences:

### What is convection?
Convection is the movement of heat through liquids and gases.

### What type of matter does convection occur within?
Convection occurs in liquids and gases.

### Explain how convection works when you boil water on a stove.
Hot water rises, cool water sinks. This creates a circular motion.

### What is density?
Density is how much mass is in a certain volume.

### Is warm air or cold air more dense and why?
Cold air is more dense. It has more mass for the same volume.

### What is a convection current?
A convection current is a flow of fluid caused by temperature differences.

### Hot air or water
Falls: Cold water
Rises: Hot air or water
Stays in place: Cool air

### What is conduction?
Conduction is the transfer of heat through direct contact.

### Explain one example of conduction that you have experienced in the last week.
I touched a hot stove and felt the heat.

### What is radiation?
Radiation is the transfer of heat through electromagnetic waves.

### Give two examples of radiation.
1. Sunlight warming your skin.
2. A microwave heating food.
