States of Matter
What are the three states of matter?
Solid, Liquid, and Gas.
What is physical change?
When the shape, size, or state changes but not the substance.
What is Density?
Density is a comparison of an object's mass to its volume.
What is Volume?
A measure of the space an object occupies.
What is Mass?
A measure of the amount of matter in an object.
What is a Boiling Point?
When a liquid boils into a gas.
What is chemical change?
When a substance changes into a new substance.
What do Denser objects do in water.
Sink
What is Volume measured in?
Cubic Centimeters and Millimeters.
What is mass measured in?
Grams and Kilograms.
What is a Melting Point?
When a solid melts into a liquid.
What is the law of conservation of mass?
Matter can neither created or destroyed.
What do less dense objects do in water?
Float
What is volume measured by?
Graduated Cylinder.
What is mass measured by?
Triple beam balence.
What is Condensation?
Gas turning into the liquid state.
Physical change.
What is the density formula?
D=M/V
What are irregular objects volume measured by?
Water Displacement.
True or False: Gravity affects Mass.
True.
What is Sublimation?
When a solid turns into a gas.
Contrast Physical and Chemical Change?
A physical change does not change a substance, a chemical change does change a substance forming a new substance.
A rectangular block of copper metal has a mass of 1869 g. The dimensions of the block are 8.4 cm by 5.5 cm by 4.6 cm. From this data, What is the density of copper?
8.9 g/cm3
If the volume is 30 ML and a rock gets added and it goes up to 40 ML what is the volume of the rock?
10 ML
Why does gravity not affect mass?
The amount of matter does not change no matter where it is.
