Object A is least dense, object C is denser than Object B but more dense than object A. Which will float?
Object A is least dense so it will obviously float.
100
This is the gravitational pull on an object measured with a scale?
What is weight

This physical property is how you make cool aid or dissolve one substance into another?
What is solubility?
100
Which state of matter has particles that vibrate in place and are very close to one another, very attracted to one another.
What are solid particles?
100
Which types of changes observe the law of conservation of mass?
Both physical and chemical
200
What is the density of an object with a mass of 14g and a density of 28ml cubed?
What is .5gml 14g/28ml=
200
This is dependent upon the amount of matter in an object and the distance from an object
What is weight?
200
These are properties that do not create a new substance such as malleability, luster or electrical conductivity?
What are physical properties?
200
What is this state of matter most likely? https://drive.google.com/file/d/0Bzmek4asbTYgUEpqUXVkTTQyU0U/view?usp=sharing
What is Liquid?
200
During a chemical change, often some of the mass appears to disappear? What happens to it?
It is changed into a gas.
300
What is the mass of an object with a volume of 14ml cubed and a density of 28ml cubed?
What is 14ml x 28ml cubed = 392g
300
This is how you measure the amount of matter in an object (mass) which can never change?
Balance
300
This property does not change into a new substance and is observed when heat is transferred from one substance to another?
What is the physical property of thermal conductivity.
300
Which particles move at high speeds and have little to no attraction to one another?
What are gas particles?
300
A burned down tree has the same mass, more mass or less mass than the tree when it was still standing.
The same. The mass of the ash and gas equals the mass of the tree.
400
How can you make a substance become less dense?
What is heat it up or add temperature?
400
Where might you have more weight than you currently do and less weight than you currently do?
On another larger planet for more weight, on a smaller planet or moon for less weight.
400
This chemical property is often labeled on aerosol sprays such as hair spray with a warning label?
What is flammability?
400
The fact that these particles expands continually means that you are describing the ______ of a ____ particle.
What is volume of a gas particle?
400
A reaction speeds up when you are gaining kinetic energy. What does this mean you are doing?
Adding temperature.
500
Name both rules for calculating density?
Only multiply when finding mass. Always divide putting mass first.
500
What of different elements combine to form compounds?
Atoms of different elements combine to form compounds.
500
Can water boiling ever be considered a chemical property? Explain
No, it can never be considered a physical property because no new substance is being created. It is always going to be H20 (water)
500
Going from a liquid to a gas would mean that you did what to the kinetic energy?
What is sped it up? or Increased it.
500
This is the law of conservation of mass.
Mass is not created or destroyed but changed from one form to another.
