<span>Physical change, heat caused this.
Water molecules that only vibrate are in solid form. If heat energy is added, the molecules will speed up their vibrations until they can break loose from the organized pattern of a solid and begin to slide over each other, changing to liquid state. If more heat energy is added, the molecules will speed up more and move randomly in all directions as a gas/vapor. Removing heat energy will reverse these changes.

This would be false. Water is a liquid at room temperature... The hottest vaporization temperature would be something that is solid at room temperature.

Explanation:
Generally Speaking...
Atoms are basically LEGO blocks of matter that are composed of protons, neutrons, and electrons.
Both protons and neutrons are located in the nucleus of an atom. As protons are are positivley charged and neutrons simlply have no charge, the identity (atomic number) of an element is characterized by the quantity of protons located in the nucleus.
Electrons on the other hand are negatively charged and are located on the outside of the nucleus. The atomic mass of an element is the total number of protons and neutrons found within the nucleus of the atom.

The answer for the following problem is explained below.
<u>The specific heat of oil is 7.98 J/gram °C</u>
Explanation:
Given:
heat (q)=878 J
mass of oil (m) =5 grams
initial temperature (
) =34°C
final temperature (
) = 56°C
To solve:
specific heat of the oil (c)
We know;
<u><em>c =q÷(mΔT)</em></u>
ΔT= () - ()
ΔT = 56°C - 34°C
ΔT = 22°C
c =
c =878÷ 110
<u>c =7.98 J/gram °C</u>
<u>Therefore the specific heat of oil is 7.98 J/gram °C</u>
