Kiewit Middle CH2
Kiewit Middle Chapter 2, "States of Matter"
| Question | Answer |
|---|---|
| What are the basic building blocks of matter called? | atoms |
| Two or more atoms bonded together are called a | molecule |
| The three states of matter are | solid, liquid, and gas |
| What are the invisible forces that hold matter together called? | bonds |
| This state of matter has strong, rigid bonds. | solid |
| This type of solid has atoms in a 3-D, repeating pattern. | crystalline |
| This type of solid lacks an orderly arrangement of atoms. | amorphous |
| This state of matter has neither definite shape nor volume. | gas |
| When this increases, the motion of atoms and molecules increases. | temperature |
| Clowns can make balloon animals because air can be | compressed |
| How can two identical balls have different pressures inside? | one has more gas in it |
| This gas law says that as the pressure around a gas goes down, the volume of the gas goes up. | Boyle's law |
| Charles' law states that | as the temperature of a gas increases, its volume increases |
| You can change the boiling point of water if you | change the air pressure around it |
| In order for the molecules in liquid water to escape | they must increase in heat energy |
| If a stinky liquid is left open in a room, the room will end up stinking because the liquid can | evaporate |
| How do the molecules of water vapor vary from liquid water? | they are faster and less orderly |
| In order for a liquid to evaporate, what has to happen? | bonds must break |
| Alcohol makes flatter droplets than syrup because it has lower..... | surface tension and viscosity |
| True or false: a liter of water boils at the same temp. as a milliliter of water. | true |
| In order for dry ice to sublimate, the CO2 gas has to....... | gain heat energy |
| Which changes of state are exothermic? | freezing, condensing, deposition |
| What is easy to do to a gas but difficult to do to a liquid? | compress it |
| Exothermic means.... | to lose heat |
| To gain heat is the definition of..... | endothermic |
| Shape and volume are definite in which state of matter? | solid |
| Only volume is defnite in which state of matter? | liquid |
| Of volume and shape, which is definite in a gas? | neither |
| Viscosity is..... | a liquid's resistance to flow |
| Which changes of state are endothermic? | melting, evaporation, sublimation |
| What force at the surface of a liquid allows a spider to walk across it? | surface tension |
| The change from solid to liquid is? | melting |
| The change from liquid to solid is? | freezing |
| The change from liquid to gas is.... | evaporation |
| The change from gas to liquid is..... | condensation |
| The change from solid to gas is... | sublimation |
| The change from gas to solid is... | deposition |
| Boiling happens when.... | the gases inside a liquid are greater than those outside the liquid |
| Vapor pressure is.... | the gas pressure inside the bubbles of a boiling liquid |
