States of Matter
How many states of matter are there?
3 (4 including Plasma)
What is defined as the amount of space an object takes up?
Volume
What is it called when a solid turns to a liquid?
Melting
How do you calculate density?
Mass/Volume
Increasing the mass of an object does what to density?
Increases Density
What state forms Lattice Structures?
Solids
What is defined as the amount of matter an object has?
Mass
What is it called when a liquid turns into a gas?
Evaporation
What are the units of density?
kg/mL or g/cm^3
Increasing Volume of an object does what to Density?
Decreases Density
What state has a fixed volume, but is the shape of its container?
Liquid
How fast particles move is determined by what?
Temperature
What is the boiling point of water in Celcius?
100
What is the density of pure water?
1 g/mL
Does changing the density of a liquid change whether an object floats or sinks?
Yes
What state has no fixed shape or volume?
Gas
What is defined as the ability for electricity or heat to flow through an object?
Conductivity
What 2 things can cause a phase change?
Temperature and Pressure
Find the density if the mass is 60g and the volume is 10mL
6 g/mL
Which has a higher density, an object with a high mass or an object with a low mass. Both objects have the same volume.
Higher Mass
What state has charged particles floating around at high temperatures?
Plasma
What is the point called where an object can be all 3 states of matter at the same time?
Triple Point
What is it called when a solid turns into a gas?
Sublimation
If an object sinks in a liquid, is the density of the object greater or less than the liquid?
Greater
Will an object with a mass of 5g and a volume of 2mL sink if placed in water?
Yes (Density of object = 2.5g/mL which is greater than 1)
