Surface Tension & Matter

Surface tension is the property of water in which...

• water molecules at the surface tend to stick together.

• water spills easily.

• water tends to be see-through.

• water tends to push up into a dome over a container before it finally spills.

Because of surface tension, you can put things into a full glass of water and...

• the water will immediately spill.

• the water won't spill for quite a while.

• the water will never spill.

• when the water spills, whatever you put in will also spill.

Matter is anything that...

• has no weight.

• has mass.

• takes up space.

• exists.

Physical properties of substances can be observed...

• by trying to change the substance into something else.

• by touch.

• by observation.

• without trying to change the substance into something else.

Chemical properties of substances can be observed...

• by trying to change the substance into something else.

• by touch.

• by observation.

• without trying to change the substance into something else.

An example of a physical property is...

• luster (shininess).

• hardness.

• translucence (light passing through.)

• flammability.
