The three states of matter can be represented by the particle model. This model explains the properties of substances in their different states, as well as changes of state.
In which state of matter are the particles furthest apart?
Which state of matter has a fixed volume but no fixed shape?
Which of these describe the particles in a solid?
Flying about in all directions
Slowly moving over each other
Vibrating around a fixed point
Which change represents evaporating?
Gas to liquid
Liquid to gas
Liquid to solid
Which of these changes occur at the same temperature for the same substance?
Melting and condensing
Melting and boiling
Freezing and melting
Which of these changes could be caused by heating a substance?
Which of the following changes involves the absorption of energy by the particles of matter?
The melting point of sulfur is 113°C and its boiling point is 445°C. What state would sulfur be in at 200°C?
The melting point of methanol is -94°C and its boiling point is 65°C. What state would methanol be at -100°C?
The melting point of oxygen is -218°C and its boiling point is -183°C. What is the state of oxygen at -200°C?
