Phase change
Question | Answer |
---|---|
evaporation | particles at the surface change from a liquid to a gas |
condensation | change of state from a gas to a liquid |
melting | change of state from a solid to a liquid |
freezing | change of state from a liquid to a solid |
sublimation | change of state from a solid directly to a gas |
boiling | change of state from a liquid to a gas |
melting - exothermic or endothermic? | endothermic |
freezing - exothermic or endothermic? | exothermic |
boiling - exothermic or endothermic? | endothermic |
condensing - exothermic or endothermic? | exothermic |
sublimation - exothermic or endothermic? | endothermic |
speed of molecules | temperature |
heat energy is released released | exothermic |
heat energy is absorbed | endothermic |
force per unit area | pressure |
property of liquids affected by attraction between molecules at the surface | surface tension |
viscosity | a property of liquids which describes its resistance to flow |
