Answer:
Thermal energy (also called heat energy) is produced when a rise in temperature causes atoms and molecules to move faster and collide with each other. The energy that comes from the temperature of the heated substance is called thermal energy.

Answer: Out of the given options bonds connecting atoms in reactants break, and bonds connecting atoms in products form are the changes which takes place when a chemical change occurs.
Explanation:
A change that leads to the change in chemical composition of a substance is called a chemical change.
For example,
Here, bond between the reactant atoms nitrogen and hydrogen is broken down.
On the other hand, bond connecting the products that is and is formed.
Thus,, we can conclude that out of the given options bonds connecting atoms in reactants break, and bonds connecting atoms in products form are the changes which takes place when a chemical change occurs.
Answer: neutral
Explanation: An atom is made up of three major sub-atomic particles namely protons, electrons and neutrons. The electrons form a cloud around the nucleus and are bound to the nucleus by electromagnetic forces.
Hello!
The molecule with the strongest intermolecular forces is CO₂ (Carbon Dioxide)
All the listed substances are nonpolar molecules, meaning that there isn't a dipolar moment (a difference in polarity resulting from the arrangement of atoms and electronegativity differences). Nonpolar molecules only have intermolecular interaction in the form of London dispersion forces.
London Dispersion Forces are stronger as the molecule size is bigger, so of the listed substances the biggest is CO₂, and it has the strongest intermolecular forces. This is evidenced by the fact that this substance has the highest boiling point of them all.
Have a nice day!
