Both substances lose their physical properties completely

Each substance maintains its own physical properties

The iron filings turn into sand

The sand becomes magnetic

Matter is destroyed and disappears

Matter changes into energy

Matter is conserved and the total amount remains the same

Matter increases in amount

Only a battery and a light bulb

A power source and wires connected in a closed path

Only wires and a switch

A battery and an open gap in the wires

Object A has a lower density than water, and Object B has a higher density than water

Object A is more dense than water, and Object B is less dense than water

Both objects have the same density as water

Density cannot be determined by sinking or floating

The sand dissolves completely and can no longer be seen

The water evaporates when it touches the sand

The sand and water each keep their own properties; the sand can still be seen and the water remains liquid

The sand and water combine to form a new solid substance

100 grams, because the sugar disappears

10 grams, because only the sugar matters

110 grams, because matter is conserved in the solution

90 grams, because some mass is lost during dissolving

Air particles are too large to fit inside a balloon

Air particles are too small to be seen with the naked eye

Air inside a balloon has no particles

Air particles only appear when heated

Thermal energy is being transformed into electrical energy

Light energy is being transformed into motion

Electrical energy is being transformed into motion

Sound energy is being transformed into electrical energy
