definitions
particles vibrate in place, lined up and close together, so they hold their shape and volume
What is a solid?
What is the density of an object that floats just below the surface of water?
The object is 1 g/cm³
An instrument which uses the change in density with the introduction of heat to measure temperature
Hint: tool that MEASURES TEMPERATURE
What is a thermometer?
the density of 10 grams of a substance which is 5 cubic centimeters
What is 2 g/cm³?
Particles sliding past each other, moving, and less dense than a solid. Because the particles 'slip and slide,' this state of matter does not hold its shape but it does hold its volume
What is liquid?
An object has a mass of 50 grams and volume of 10 cm³. This object will _____ in water.
What is sink?
A term for several properties that stay the same no matter how much you have of a substance, which might help you identify an unknown element
What is a characteristic property?
If you have a piece of wood that is 48 g and 2 cm³, and you cut it in two pieces measuring 12 g and 36 g: Tell the density of each piece
What is 24 g/cm³?
Particles are far apart, moving very quickly and with very low density. Because the particles are as far apart as they can be, this state of matter will not hold its own shape or volume
What is gas?
A cube sinks in water. It raises the water from 10 mL to 25 mL. The size of the cube is...
15 cubic centimeters
If I add heat to a balloon, the particles will get more energy and move further apart. How will the affect the density?
What is... the density will decrease?
The the force of gravity as measured in Newtons or grams of force.
What is weight?
The 2 cm³ of iron which is 8.76 g/cm³ would have what mass?
What is 17.52 g
Energy produced or transferred from one substance to another in any way other than as "work"
What is heat?
The physical law that states that an object is pushed upward by a force equal to the weight of fluid it displaces.
What is Archimedes Principle/Buoyancy?
If I add salt to a cup of water, the density will...
what is increase, because I have increased the mass in the same amount of space?
A characteristic property defined as the amount of mass in a given volume.
What is density?
This is a metal which you calculated the density to be 2.7 g/cm³
What is the density of aluminium? (you do not need to memorize this or any densities other than the density of water)
A 25 cm³ block sinks in water. Its mass must be...
Greater than 25 g
