Matter and Its Interactions

A student notices that an inflated balloon gets larger when it is warmed by a lamp. Which best describes the mass of the balloon as a result of this change? 

• The mass of the balloon increases because the size of the balloon has increased. 

• The mass of the balloon increases because the temperature of the balloon has increased. 

• The mass of the balloon stays the same because the gas inside the balloon still has the same mass after it warms up. 

• The mass of the balloon stays the same because warming decreases the mass enough to cancel out the effect of increasing the size.

The four states of matter are shown with these illustrations. 

Differentiate between these four states of matter by completing the chart. Click and drag each description to its correct state of matter.

• conforms to the shape of its container but retains a nearly constant volume independent of pressure

• Plasma

• maintains a fixed volume and shape.

• Liquid

• has both variable volume and shape; expands to fill container.

• Solid

• electrically conductive, produce magnetic fields and electric currents

• Gas

A student drew a representation of the atoms of a solid. The illustration shows closely packed atoms vibrating, but remaining in the same relative positions. Which of the following changes must the student make to the illustration to accurately represent the same substance in the liquid phase?

• Each individual atom should be much larger

• There should be very wide spaces between the atoms

• The illustration should show increased movement of the atoms

• The shape of each atom must reflect the shape of the container
