Educational worksheet featuring science questions on water properties, states of matter, and weather concepts.

Let's go through each of the questions in your image and solve them one by one, with explanations:

---

#1) At what temperature does water freeze?

Options:
a) 75° Fahrenheit
b) 35° Celsius
c) 32° Fahrenheit
d) 26° Celsius
e) 26° Fahrenheit
f) none of these

✔ Correct Answer: c) 32° Fahrenheit

Explanation:
Water freezes at 0°C (32°F) under standard atmospheric pressure. This is a key point in the Celsius and Fahrenheit scales. So, 32°F is the correct freezing point.

#2) The amount of water vapor in the air is called:

Options:
a) condensation
b) precipitation
c) humidity

✔ Correct Answer: c) humidity

Explanation:
- Humidity refers to the amount of water vapor present in the air.
- Condensation is the process where water vapor turns into liquid (like dew or clouds).
- Precipitation is when water falls from the sky (rain, snow, etc.).

So, "humidity" is the correct term for the amount of water vapor in the air.

#3) What kind of air rises faster, hot or cold?

✔ Correct Answer: Hot air

Explanation:
Hot air is less dense than cold air because the molecules move faster and spread out. Because it's less dense, it rises more quickly. Cold air is denser and sinks. This principle is important in weather systems and convection currents.

#4) A cloud is a collection of millions of tiny water droplets, true or false?

✔ Correct Answer: True

Explanation:
Clouds form when water vapor in the air condenses into tiny water droplets or ice crystals. These particles are so small they remain suspended in the air, forming visible clouds. So yes, a cloud is made up of millions of tiny water droplets (or ice crystals in colder conditions).

#5) Water can be in all 3 states of matter. It can be a solid, liquid, or ________?

✔ Correct Answer: gas

Explanation:
The three states of matter are:
- Solid (ice)
- Liquid (water)
- Gas (water vapor)

So, the missing state is gas.

*(Note: The image shows icons for solid (ice), liquid (water), and gas (steam/cloud).)*

#6) When something gets colder, do the particles in that substance start to slow down or speed up?

✔ Correct Answer: Slow down

Explanation:
Temperature is a measure of the average kinetic energy of particles. As a substance cools, its particles lose energy and move slower. When it heats up, particles gain energy and move faster.

So, when something gets colder, particles slow down.
