Question

when heat is liberated by matter the energy of its molecule____ and they come closer...."fill in the blanks"

Answer 1

Blank 1 - "Decreases"
Blank 2 - "to stability"

Answer 2

When heat is liberated by matter the energy of its molecule decreases and they come closer.

• Heat energy liberation is the loss of heat energy. This is seen as a decrease in the kinetic energy of the particles due to a drop in velocity.
• Since there is a loss of kinetic energy, the molecules do not move fastly and apart. Rather they come closer.
• Thus, heat energy liberation is associated with the closeness of molecules.
• The temperature gradient results in the transfer of heat energy or thermal energy .
• The matter is most commonly defined as anything that occupies space and has matter.
• Molecules are a group of atoms that may be made of the same atom or made of different atoms.
• Example of molecule is oxygen gas, hydrogen chloride, etc.
