Name one solid that is less dense than it's liquid state.
What is water.
200
What is kinetic energy?
What is the energy of motion.
200
What is density and it's formula?
What is the mass in a given volume and mass/volume.
200
How dense is hydrogen?
What is 0.00009g/mL.
300
What are the measurements used for liquids?
What is milliliters (mL), liters (L), or cubic centimeters (cm3)

What is thermal expansion and contraction?
What is basically expanding and contracting when temperature changes. Any matter that expands when the temperature increases is called thermal expansion. Any matter that contracts when the temperature decreases is called thermal contraction.

What is matter, mass and volume.
What is matter is anything that has a mass and a volume. Mass is the quantity a substance or object contains. Volume is the amount of space taken up by a substance or object.

What is the difference between heat and temperature?
What is the energy transferred from one material or object to another as a result of a difference in temperature or a change in state and the average kinetic energy of its particles.
400

What happens to melted sugar that has been hardened again?
What is that it will become even more dense than before it was heated.
500
List all the changes of states plus if heat is added or removed.
What is Evaporation, Condensation, Melting, Solidification, Sublimation and Deposition. Evaporation is heat added. Condensation is heat removed. Melting is heat added. Solidification is heat removed. Sublimation is heat added and Deposition is heat removed.

What are the 4 main points of the Kinetic Molecular Theory?
What is all matter is made up of very small particles (atoms and molecules), there is empty space between particles, particles are constantly moving and energy makes particles move.
500
