<h2>It can happen when liquids are cold or when they are warm. ... It turns out that all liquids can evaporate at room temperature and normal air pressure. Evaporation happens when atoms or molecules escape from the liquid and turn into a vapor. Not all of the molecules in a liquid have the same energy.</h2>
Answer:
Number of valence electrons
Explanation:
The recipe for an omelet are:
<u>Ingredients</u>
- 1 Egg
- Salt and pepper ( 1 tablespoon )
- Butter ( 1 tablespoon )
<u>Recipe:</u>
- Turn on the heat and place a pan on it.
- Add butter to the pan.
- Crack the egg and whisk it properly.
- Add the whisked omelet onto the pan and stir.
- Add salt and pepper.
<h3>How to illustrate the information?</h3>
When we turn on the heat and place the pan, a heat transfer takes place and heat transfers from one body to another.
When we add butter to the pan, then the temperature of the pan was more than that of the butter.
Since the melting point of butter was less than the temperature of the pan, the the melting of butter takes place.
When we add the egg, the evaporation of the liquid present in the egg yolk and the egg white takes place.
These are the chemical reactions depicted.

<span>Answer:
The dilution formula is V1M1 = V2M2.
We need 3 of the values to calculate the 4th.
We have the original volume (2 mL of copper ion solution) and the final volume (20 mL), but we don't have the concentration of either the original or the final copper solution,
All we can say is the resulting solution is 10 times as dilute as the original was-
V1M1 = V2M2
2Ă—0.200 = 20Ă—M2, so M2 = 0.400/20 = 0.020M</span>
