Properties of Matter- Part 1
Term | Definition |
---|---|
matter | Anything that has mass and takes up space (has volume). |
mass | the amount of matter in an object. It is measured on a balance in grams/ kilograms. |
volume | the amount of space an object takes up. It is measured with a ruler or graduated cylinder/beaker |
state of matter | the classification of matter as a solid, liquid, or gas. |
solid | a type of matter with tightly packed particles that keep their shape and can vibrate |
liquid | a type of matter with loosely packed particles which can move and take the shape of the container they are in; Liquids are ‘pour-able’ |
gas | a type of matter with very scattered particles that move very fast; it can take the shape of a container. |
temperature | the measure of thermal energy’s motion (movement) in an object; more moving thermal energy = hot less moving thermal energy = cold |
physical property | are characteristics of matter that can be observed and measured, such as mass, volume, state of matter, density, magnetism, solubility, and conduction. |
particles; atoms | the smallest part of matter; what all matter is made of |
freeze | changes in the physical property of a liquid when heat is taken away and it becomes a solid. (liquid changes to a solid) |
melt | changes in the physical property of a solid when heat is added and it becomes a liquid. (solid changes to liquid) |
boil | changes in the physical property of a liquid when heat is added and it becomes a gas at a specific temperature. (liquid becomes a gas) |
condensation | changes in the physical property of a gas when heat is taken away and it becomes a liquid. (gas changes back to a liquid) |
evaporation | the process of changing liquid water into water vapor (gas) when thermal (heat) energy is present-(which is always) |
water vapor | the gas state of water |
physical change | when substances go through a change and no new substance is created. (Ex. water has a physical change when it is cooled and changes into ice... it is still water, just a solid now) |
