Solids
How are particles in a solid arranged?
Tightly packed together
How are the particles in a gas arranged?
Far apart and move quickly
What type of solid has structured and ordered particles? When solids like this break, they break in clean, predictable lines
Crystalline Solids
What is it called when a liquid becomes a gas? When a gas becomes a liquid?
Evaporation/Condensation
Name three examples of gasses.
Carbon dioxide, methane, oxygen, any of the noble gasses
What type of solid has particles that are arranged randomly and break at points where there is more stress?
Amorphous Solids
On the pH scale, what numbers are acids and what numbers are bases?
0-6 are acids and 8-14 are bases; 7 is neutral
What is the gas produced when people bake muffins, bread, etc?
Carbon dioxide
What is called when a solid turns into a liquid? When a liquid turns into a solid?
Melting/Freezing
Windex has a pH of 11. Is it an acid or a base?
Base
Name three areas where gasses will behave irregularly because of cold temperatures.
North pole, south pole, high altitudes like Mount Everest
What is it called when a solid turns directly into a gas? When a gas turns directly into a solid?
Sublimation/Deposition
Acids- vinegar, juice, milk, battery acid
Bases- ammonia, Windex, soap
Under what circumstances do gases behave irregularly? (we would need to use the van der Waals equation rather than the ideal gas law)
high pressure, low temperatures
