What is thermal conductivity?
Thermal conductivity is the rate at which a substance transfers heat.

What is matter and what is mass?
Matter is anything that has mass and takes up space. Mass is the amount of matter in an object.
100
What is a physical change?
A physical change is change that affects one or more physical properties. Physical changes do NOT affect the identity of the substance.

If a desk has a mass of 200 g, and a volume of 20 cm^3. What is it's density?
The density of the desk is 10g/cm^3.
200
What is density and what is it's equation?
Density is the amount of matter in a given volume d=m/v
200
What is volume?
Volume is the amount of space an object takes up.
200
What is a chemical change? Provide an example.
A chemical change is when one or more substances change into NEW substances. An example of a chemical change is rusting or combustion.

What the density of a boat that has measurements of 600 cm^3 and 1800 g
The density of the boat is 3g/cm^3.
300
What is ductility? What is malleability?
Ductility is the ability of a substance to be pulled into wire. Malleability is the ability of a substance to be rolled or bent into various shapes without breaking.

The liquid you have is 0.80 g/mL. Would the following blocks sink of float? Block A = 2 g/cm^3 Block B = 0.65 g/cm^3 Block C = 0.82 g/cm^3
Block A would sink. Block B would float. Block C would sink.
400
What is reactivity?
Reactivity is an objects ability to react or change because of a chemical change.
400
What are the units for solid volume and liquid volume? What are the units for solid density and liquid density.
Solid volume: cm^3 Liquid volume: mL Liquid Density: g/ml Solid Density: g/cm^3
400
Is changing from a solid to a liquid a physical or chemical change? Why?
It is a physical change, since the identity of the substance is not changing.
400
What is the volume of the rock that is 32 g and 2 g/cm^3 ?
The volume of a rock is 16 cm^3.
500
What is combustion? What is oxidation?
Combustion is flammability. Oxidation is rusting.

What is the density of water? Make sure to add units.
The density of water is 1.00 g/ml.
500
Frying an egg is an example of a ___________ change.
Frying an egg is a chemical change.

I poured three liquids into a glass. Their densities were: 10g/mL, 0.25g/mL, and 0.5g/mL. The red liquid went to the bottom of the glass, blue to the middle, and the orange floated on the top. What is the density of each of the liquids?
red=10g/mL, blue= 0.5g/mL, orange= 25g/mL.
