By start heating the water so,
1- the physical changes to the water will begin by going through different states of matter such as solid, liquid and gas vapor.
2- Water is a compound, not an element (H2o).
3- It will change according to the temperature change also:
a- At zero C° it is at a freezing temperature.
b- when it starts to be heated from 0C° to 100 c°, it starts to change from freezing to the liquid state.
c- At 100C° the water starts to change from liquid to vapor state until it disappears.
The answer is (3) moles of solute per liter of solution. That is what the definition of molarity of a solution means. The equation is concentration = mol number of solute/ volume of solution.

Answer:
The answer to your question is 6.72 x 10²⁰ atoms
Explanation:
Data
Avogadro's number = 6.022 x 10²³ atoms
Volume = 22.4 L
Volume 2 = 25 ml
Number of atoms = ?
Process
1.- Convert mL to L
1000 mL ----------------- 1 L
25 mL ------------------ x
x = (25 x 1) / 1000
x = 25 / 1000
x = 0.025 L
2.- Use proportions and cross multiplication to find the answer.
22.4 L ----------------- 6.023 x 10²³ atoms
0.025 L -------------- x
x = (0.025 x 6.023 x 10²³) / 22.4
x = 1.51 x 10²² / 22.4
x = 6.72 x 10²⁰ atoms
