Density
What is the Formula for Density?
D= M/V
What do Protons represent?
The Identity of an Element.
What do groups look like in the Periodic table?
Vertical Columns
In what direction does heat flow?
From warm to cool
Which state(s) of matter has a fixed volume?
Liquid and solid
If Liquid A is more dense than Liquid B where would Liquid A be if they were put into a glass?
Liquid A would be at the bottom or under liquid B
What do atoms make up?
Matter or Everything
What do Periods look like in the Periodic table?
Horizontal Rows
True or false. It is possible to lose heat from an object to the surrounding air.
True
What do molecules in a solid do?
They vibrate.
How would you find the Volume of a liquid if given the density and mass.
V = M/D
What is the middle of the atom called that contains the protons and neutrons?
The Nucleus
True or false. Elements in the same group have similar chemical properties.
True
If a ball that is 50°F is dropped in a bucket of water that is 100°F what will happen?
The heat will transfer from the water to the ball.
True or False. Gas has a definite volume.
False
What is the unit for density?
Mass per volume. ex. g/cm3.It is not definitive and can change based on what units are being used.
What charge does an electron have and does its mass contribute to the overall weight of the atom?
Negative. No, it does not contribute to the weight of the atom.
True or false there are 6 periods.
False. There are 7.
If you drop ice in hot tea what direction(s) can the heat flow?
The heat from tea to the air or tea to the ice.
What do the molecules of water do?
Slide past one another
Explain in your own words the steps that you would take to find the density of an object given the volume and mass. Also include units. (you can make up your own units)
divide the mass by the volume
Name all the parts of the atom and their charges.
Neutron- Neutral
Proton- Positive
Electron- Negative
What are the vertical columns and horizontal rows called?
Column-Group
Row-Period
If you are holding a cold piece of metal in your hand will the metal become warm? why or why not?
Yes because the heat from your hand will transfer to the cool metal.
What are 2 things that can happen to a substance when temperature decreases?
Condensation or freezing.
