What must be added or taken away for a change in the state of matter to occur?
I believe "heat"To change from one state of matter to another state of matter heat is added or taken away.I think that makes sense!
Does boiling an egg increase its mass?
as long as the shell doesn't crack no. Adding heat to something wont change its mass unless something is added or taken away from the egg
What is the complete subject of the sentence - To change a liquid to a solid heat must be taken away?
heat
Is sublimation exothermic or endothermic?
Sublimation is an endothermic phase transition from solid to gaseous state.
When heat is taken away from matter it loses energy and its temperature decreases?
yes
Is heat taken away or added in evaporation?
Taken away. As a liquid evaporates, it loses heat to the atmosphere.
Heat being added or taken away from a substance may cause?
more or less heat

Is energy gained during sublimation?
Energy is added when sublimation occurs, because it skips the liquid sates and goes strait from a solid to a gas. And to break particles apart, you must add heat, so energy is gained.
What has to be taken away to turn ice into water?
heat
What are affected by an increase in intermolecular forces?
Capillary attraction, Melting point, Heat of vaporization Sublimation temperature, Surface tension, Vapor pressure, Heat of fusion Boiling point, Viscosity, Density, Heat of sublimation Apex: Boiling point, viscosity, heat of sublimation, density.
What is common between melting and evaporation?
they either take away heat or heat is added.
What happens to water when heat is taken away?
It becomes cold.
When heat is taken away what happens to the speed of the molecule?
It slows.
