Question | Answer |
---|---|
Kind of mixture where one substance dissolves into another. Examples would be sugar water, salt water | Solution |
Kind of mixture where "suspended" particles settle to the bottom over time. Examples would be muddy water and salad dressing. | Suspension |
A substances resistances to flow. The thicker the liquie, the slower it pours. | Viscosity |
A subtance that is bendable or moldable. It can be hammered into a sheet | Malleability |
The temperature that a substance melts. | Melting point |
The temperature that a substance boils. | Boiling point |
Property where heat or electricity can travel through a substance. This is mostly metals | Conductivity |
A substances mass per unit of volume(mass divided by volume). | Density |
This process separates a mixture based on boiling point and condensing | Distillation |
This process separates a mixture based on the size of the particles | Filtration |
A change to a substance that DOES NOT change what the substance is. Examples would be tearing paper, mowing the lawn, melting butter | Physical change |
Change to a substance when the substance changes to a new one. Examples would be burning paper, rust on a car, melting a candle | Chemical change |
Three kinds of chemical changes. How do you know there is a new substance? | 1. a change in color----banana 2.production of a gas---mixing baking soda and vinegar 3. formation of a precipitate---chunky milk |
The ability of a subance to burn in the presence of oxygen | Flammability |
A solid that forms and separates from a liquid mixture | Precipitate |
Two types of pure substances | elements and compounds |
A substances made of only one kind of atom. CANNOT be broken down | Element |
A substance made of two or more simple substances. CAN be broken down | Compound |
A mixture is classified as a solution, colloid, or suspension based on....... | The size of its particles |
Temperature that water melts/freezes | 0 degress Celsius |
Temperature that water boils | 100 degress Celsius |
Compounds that form when a candle burns | Water and carbon dioxide |
