Chemistry Vocab

3. The standard unit of temperature in the metric system of units
5. The Standard International ( SI ) unit of thermodynamic temperature
6. A substance that takes part in and undergoes change during a reaction.
11. The quantity of heat necessary to change 1 g of a solid to a liquid with no temperature change.
12. The movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.
15. Energy that comes from a source and travels through space at the speed of light.
17. Used to measure amounts of heat transferred to or from a substance.
18. The energy that comes from motion

1. Accompanied by the release of heat.
2. The heat required to raise the temperature of the unit mass of a given substance by a given amount
4. The amount of heat needed to turn 1 g of a liquid into a vapor, without a rise in the temperature of the liquid.
7. The branch of chemistry concerned with the quantities of heat evolved or absorbed during chemical reactions.
8. The result of the movement of tiny particles called atoms, molecules or ions in solids, liquids and gases.
9. The chemical substances which are formed due to a chemical reaction between two or more chemical substances
10. The amount of energy needed to warm 1 g of H2O by 1°C
13. The energy contained within a system that is responsible for its temperature
14. The process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material.
16. The SI unit of energy, work, and heat
19. Accompanied by or requiring the absorption of heat.
