Matter- Test 10/16/15 Flashcards
How do I measure volume ?
You measure and calculate water displacement
Units of volume
ML, liters, Cm 3 (cubed)
What is mass
Mass is the amount of stuff in an object
What’s the difference between weight and mass
Mass never changes, weight changes depending on location.
How do you find mass
Triple beam balance
Units of mass
KG, GRAMS
What is weight
Weight is how much gravity pulls on an object
How do you measure weight
Spring scale
Units of weight
Newtons
What is density
Density is how tightly matter is packed in a space
How do you find density
Mass/volume
What are the units for density
G/cm 3 (cubed)
Example of intrinsic properties
Melting point, solubility, density
Examples of chemical properties,
Reactivity, flammability
What are physical properties
Physical properties are properties you can observe with your 5 senses.
What are chemical properties
Chemical properties are when matter interacts with another matter and it changes.
What are general properties
Every form of matter has general properties
What are Intrinsic properties
Intrinsic properties are properties that dont change
The best way to find the volume of an irregular shape is to…
Use the water displacement method.
What is volume
Volume is the amount of space a thing (matter) takes up.
