MT.6 LT.2 Flashcards
What are physical properties? Then give examples
Properties that can be observed directly or measured without change the chemical identity of the substance. Ex. mass, volume, shapes, size, color, luster, hardness
Describe melting point
Temperature at which a solid become a liquid
Explain Boiling point
Temperature at which a liquid becomes a gas
What is viscosity? What are high and low viscosity?
A fluids resistance to flow. Syrup high water low
Solubility is?
A measure of how well a solute dissolve in a solvent
Explain Solute, Solvent, and Solution
Solute what is being dissolved, Solvent is what is doing the dissolving, the solution is the result
What is density?
Measure of compactness or consistency of a material?
What is density’s equation and measurement
Mass divide by Volume. g/ML or g/cm3
volume of a solid equations
Rectangle shape V=L x W x H. Cylinder V= pie R 2 H. measured in cm3
Volume of liquid
used for irregular shapes not cube or cylinder
How to use volume of liquid in a equation
final volume - initial volume = volume
Explain chemical properties and give examples
Properties that can only be observed or measured by changing the chemical identity of a substance Ex. Toxicity, flammability, combustibility, radioactivity
Describe Combustibility
how flammable a substance is
Describe reactivity
how easily a substance reacts, usually with acid or base
Describe oxidation
How easily a substance reacts to oxygen and moisture which will rust of time
What is physical change and examples
A change in a substance that only affects its physical properties Ex. Cutting, Coloring, Crushing, Melting, Boiling
what is chemical change and examples
A change in a substance that affects its chemical properties thus a CHEMICAL REACTION occurs and a new substance is formed
Explain Chemical Reaction
Process by which the atoms of one or more substance are rearranged to form different substance
