Matter
| Question | Answer |
|---|---|
| Define matter. What are some of its properties? | Something that has mass and volume. It cannot be created or destroyed. |
| Define mass. How do you measure it? | Mass is the amount of matter in something. Measure using a balance. |
| Define volume. How do you measure it? | Volume is the amount of space something takes up. Measure using a beaker. |
| Define temperature. How do you measure it? | Temperature is a measure of the energy of motion of the particles in matter. Measure with a thermometer |
| Define density. | Density is found by dividing an object's mass by its volume. A gas with less density than another will float on top. |
| Define liquid. | A liquid is a substance that has a definite volume but does not have a definite shape. Particles in a liquid move slower than particles in a gas and they slide past each other. |
| Define gas. | A gas is a substance that does not have a definite shape or volume. Particles move very quickly and are far apart from each other. |
| Define solid. | A solid is a substance with a definite shape and volume. the particles are very close to each other. they don't move but they vibrate in place. |
| What does the CONSERVATION OF MASS say? | during physical and chemical changes, matter can change appearance or identity but the total mass of matter is the same before and after the change. |
| What is a mixture? | A mixture is a combination of 2 or more substances that keep their identities. They DO NOT undergo a chemical change. This is a PHYSICAL CHANGE. |
| What is a solution? | A solution is a mixture that has same composition throughout. One substances dissolves in another. |
| When temperature increases, the speed of a chemical change _________. | When temperature increases, the speed of a chemical change INCREASES. |
| What has a larger volume? A) 1 L of water at room temperature B) 1 L of water that started at room temperature and then has been put into the freezer for 24 hours | What has a larger volume? B) 1 L of water that started at room temperature and then has been put into the freezer for 24 hours Ice or frozen water takes up more volume than liquid water |
| What is a chemical reaction? | A chemical reaction is the process in which new substances are formed during a chemical change. |
| solubility | the ability of a substance to dissolve in another substance |
| ductility | the ability of a substance to be pulled into a wire |
| conductivity | the ability of a material to allow heat or electricity to flow through it |
| buoyancy | the ability to float |
| viscosity | the property of a fluid that shows resistance to flow |
| malleability | The ability of a metal to be flattened into thin sheets |
| magnatism | a physical property produced by the motion of electric charge, resulting in attractive and repulsive forces between objects (so that some object can attract iron) |
