Matter (Physics)

the temperature of a substance remains unaffected during state change

• true

• false

• sometime true,
  sometime false

water evaporates at boiling point

• true

• false

boiling takes place at all temperatures

• true

• false

the change of state that happens at all temperatures

• evaporation

• boiling

• condensation

• freezing

the change of state which is reverse of melting

• sublimation

• boiling

• condensation

• freezing

boiling point is

• the change of liquid to gaseous state

• all liquids boil at 100^o C

• the temperature at which a liquid changes to gas

the intermolecular space is maximum in

• liquids

• gases

• solids

molecules of a substance in any state are in constant motion because they have

• kinetic energy

• potential energy

• intermolecular force of attraction

• intermolecular spaces

the state of matter in which particles vibrate

• gases

• solids

• liquids

rapid conversion of water into steam is an example of

• melting

• evaporation

• vaporization

• freezing
