I NEED HELP PLEASE WITH THESE QUESTIONS :

1. Lighting a match is .
2. The evaporation of water is .
3. Cooking an egg is .
4. The condensation of water from vapor in the air is

1. Lighting a match uses chemical energy.

2. The evaporation of water is created from thermal energy.

3. Cooking an egg uses thermal energy to cook.

2. The condensation of water from vapor in the air uses thermal energy.

Explanation:

1. Lighting a match uses chemical energy which is then converted into thermal energy.

2. Evaporating water can be cause by hot items like the Sun which plays the most important role in our water cycle by evaporating water.

3. Cooking an egg uses thermal energy because it take the heat away from the object used to cook with it.

4. The condensation of water from vapor in the air is from cool surfaces.

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
