Q. What are all the exothermic techniques that change the state of matter?
A. freezing and condensation
Q. What is a melting point?
A. a temperature at which a solid turn into a liquid
Q. What is a pure substance?
A. A substance with a single chemical element that is free from impurities
Q. which state of matter do these characteristics describe? volume is fixed, density is high, has a
definite shape, does not flow particles, are packed close together tightly in a regular pattern
A. solid
Q. what describes the property of how easily a liquid evaporates and boils due to weak intermolecular
forces?
A. Volatility
Q. what are all the endothermic techniques that change the state of matter?
A. melting, evaporation and boiling
Q. which state of matter do these characteristics describe? volume is fixed, density is between
moderate and high, doesn't have a definite shape as it expands to take the shape of the container,
flows very easily, particles are packed close together in a random pattern
A. liquid
Q. What is condensation?
A. the change of state from gas to liquid at below freezing point temperatures note: freezing point is a
temperature at which a liquid turn into solid
