MYP 1 Matter Study Stack
| Term | Definition |
|---|---|
| Matter | Matter is anything that has volume and mass |
| Mass | Mass is the amount of matter found in an object The unit of mass is grams (g) |
| Volume | Volume is the space occupied by an object. The unit of volume is centimeter cubed ( cm3) |
| Matter is made up of | particles called atoms, molecules or ions |
| States of Matter | solid, liquid and gas |
| Density | The mass of matter found in one cm3 of a substance |
| Absolute temperature | The temperature at which particles stop moving |
| Movement of particles | Particles of solids vibrate in one place Particles of liquids vibrate, rotate and move around Particles of gases vibrate, rotate and move around |
| Flow | Solid particles cannot flow Liquid particles can flow from one place to another Gas particles can flow from one place to another |
| Compression and Volume | Solids have a fixed volume. They cannot be compressed. Liquids have a fixed volume. They cannot be compressed. Gases have a changeable volume. They can be compressed. |
| Shape | Solids have a fixed shape. Liquids take the shape of the bottom of the container Gases take the shape of the whole container |
| How do you measure mass of a solid | Use a digital balance |
| How do you measure the mass of a liquid | Measure the mass of an empty beaker. Add the water and measure the mass. Subtract the the mass of the empty beaker from the beaker+water. |
| How do you measure the volume of water | Use a measuring cylinder |
| How do you measure the volume of a cube or cuboid | length x height x width (l x h x w) The unit is cm3 |
| How do you measure the volume of an irregular solid? | Put the solid in a measuring cylinder filled with a known volume of water. The change in volume is equal to the volume of the solid. |
| What is the equation for density? | mass/volume |
| What is the unit of density? | g/cm3 |
| What is the density of water? | 1 g/cm3 |
