The water molecules increase their speed.

This is because when an object is in its solid form, the molecules are packed closely together, restricting movement.

On this table;

Solid

Liquid

Gas

Liquid is the next step on the ladder, and going from up to down, the molecules speed up and desperate.

**Answer:**

**Explanation:**

The Bernoulli equation is:

**(1)**

**P** is pressure related to the fluid**ρ** is the density of the fluid (ρ(air)=1.23 kg/m³)**v** is the speed of the fluid**h** is the displacement from one position to the other

Now let's apply the equation (1), for our case:

**(2)**

here we assume that h is the same in both cases so it canceled out.

- <u>subscript 1</u> is related to the upper surface of the wings
- <u>subscript 2</u> is related to the low surface of the wings

Solving the equation for v₁ we have:

**(3)**

Now, we know that pressure P=F/A (force over area)

**(4)**

Combining (3) and (4), we can find v1.

I hope it helps you!

**Answer:**

Water is the solvent, therefore (B

**Explanation:**

Water is called the "universal solvent" because it is capable of dissolving more substances than any other liquid.

This has to do with the polarity of each water molecule. The hydrogen side of each water (H2O) molecule carries a slight positive electric charge, while the oxygen side carries a slight negative electric charge. This helps water dissociate ionic compounds into their positive and negative ions.

A bolt of lightning<span>, which can reach temperatures of roughly 30,000 kelvins (53,540 degrees Fahrenheit). The sun, on the other hand, is eclipsed in this case, its surface temperature is just 6,000 kelvins (10,340 degrees Fahrenheit)
