S1 Matter
Solids, Liquids and Gases
| Question | Answer |
|---|---|
| What are the three states of matter | Liquid, Solid , Gas |
| Give an example of a liquid | One could be: Water, Milk etc |
| Give an example of a solid | Could be: Rock, Iron, Wood etc |
| Give an example of a gas | Could be: Carbon Dioxide, Oxygen, Hydrogen |
| What is matter | All of the stuff in the world is matter. anything that takes up space is matter. |
| What is a measuring cylinder used for? | It meaures the volume of liquids |
| How is a measuring cylinder used to measure the volume of a solid object? | You put the object into the measuring cylinder and compare the water level before and after. The increase is the volume of the object. |
| The curved water line in a graduated cylinder is called….. | A meniscus |
| How do you calculate the volume of a solid? | Length x width x height |
| How do you calculate density? | Mass divided by volume |
| Define volume. | How much space matter takes up |
| Define density. | Relates the mass of an object to its volume |
| Define Mass. | The amount of matter in an object |
| What unit do you use to measure matter? | Grams |
| What unit do we use normally use to measure volume? | Centimetres cubed |
| Matter is anything.... | which occupies space and has mass |
| Mass is the ... | amount of matter in anything |
| Mass is measured in ... | grams |
| Solids have a….. | fixed shape and volume |
| Liquids have a fixed… | Volume |
| Liquids have no fixed… | Shape |
| Gases have no fixed… | Volume OR Shape |
| Why can gases be compressed? | Because there are large spaces between its particles. |
| What word do Scientist use to describe the change that takes place in the size of substances when they are heated? | Expansion |
| Are gas particles are free to move? | Yes |
| When a solid changes to a liquid this is called… | Melting |
| When a liquid changes to steam this is called.. | Boiling |
| When steam changes to water this is called…. | Condensing |
| When water changes to ice this is called…. | Freezing |
| If a liquid changes to a gas slowly this is called…. | Evaporating |
| Diffusion is the movement of particles from an area of…. | high concentration to an area of low concentration until it is evenly spread. |
| Can liquids be compressed? | NO |
| Can gases be compressed? | YES |
| What word do Scientist use to describe the change that takes place in the size of substances when they are cooled? | Contraction |
| Do the particles of a substance increase in size when they are heated? | No - the spaces between the particles increase in size. |
| Do the spaces between the particles of a substance decrease in size when they are cooled? | Yes |
| In which state of matter does Diffusion take place fastest? | Gases |
