Secondary 2 Science Fun

4. - The force that attracts two bodies towards one another, due to their mass.
6. - The study of heat and energy transfer between systems.
7. - A protein that acts as a biological catalyst to speed up chemical reactions in cells.
10. - The tendency of an object to resist changes in its state of motion.
11. - The transfer of heat through a fluid (liquid or gas) caused by molecular motion.
13. - The repetitive back-and-forth movement in a regular rhythm, such as a pendulum or wave motion.
16. - A measure of disorder or randomness in a closed system.
20. - Relating to the interrelation of electric currents or fields and magnetic fields.
21. - A substance that increases the rate of a chemical reaction without undergoing any change.
22. - Variants of a particular chemical element that differ in neutron number.
23. - The process where water is absorbed by plants and released as vapor through small pores in the leaves.

1. - Refers to concepts and laws defined by Sir Isaac Newton, especially in mechanics and motion.
2. - Organelles found in cells, known as the powerhouse of the cell where respiration and energy production occur.
3. - The quantity of motion an object has, calculated as the product of its mass and velocity.
5. - The combining power of an element, especially in forming compounds or molecules.
7. - A condition in which all acting influences are balanced in a stable system, particularly in chemical reactions.
8. - The phase transition of a substance directly from a solid to a gas without passing through the liquid state.
9. - A measure of a fluid's resistance to flow.
12. - The ability of an object to float in a fluid due to the upward force exerted by the fluid.
14. - The process where light energy is converted to chemical energy in plants.
15. - A chemical reaction that involves the gain of electrons, often associated with the loss of oxygen.
16. - The chemical decomposition produced by passing an electric current through a liquid or solution containing ions.
17. - The process by which molecules spread from areas of high concentration to areas of low concentration.
18. - The process by which plants convert light energy into chemical energy.
19. - The process in which a substance loses electrons, often associated with the gain of oxygen.
