100
freezing
What is it called when a liquid turns into a solid?
100
motion
The particles that make up matter are in a constant state of?
100
Divide mass by volume. 5g divided by 10cc is 0.5g/cc
How would you calculate the density of 10cc of a substance that weighs 5grams.
100
The water molecules on the surface do not have molecules above to be attracted to therefore they bond to those next to them like people interlocking arms this causes a "net" affect to the surface.
Explain how polarity causes surface tension.
