All About Matter
Anything that has mass and takes up space.
Matter
Transfer of thermal energy at different temperatures.
Heat
The thickness of the air is measured by its _________.
Density
What are the parts of an atom?
In the nucleus there is the proton and neutron. Circling the nucleus are electrons.
2 or more elements chemically combined.
Compounds
Everything is made up of _________.
Particles/atoms.
Pure water melts at what temperature?
0o Celsius
As the elevation increase, the boiling point ________.
What are the two types of atomic bonds? How do they work?
Ionic bonds give an electron to another element. Covalent bonds share electrons with each other.
Diatomic molecule
Gases have an _____________ shape and volume.
What state is a substance in if the temperature of a substance is between its melting and boiling points?
Liquid
True or False: There are less molecules of air at higher elevations so air pressure is less.
Crystals.
True or False: The properties of compounds are different from the properties of the elements in it.
True.
State of matter where it has indefinite shape but definite volume.
Liquid
Would the boiling point of a substance increase or decrease if it is impure?
Increase
Water at sea level boils at a _________ temperature than water at the top of Mt. Everest
Higher
What is the relationship between elements and atoms?
The different types of atoms are called elements.
Pure sodium and pure chloride are both dangerous. However when they combine they produce ___________.
A solid crystal that is safe to touch.
How can particle interactions explain the properties and behavior of dry ice?
As a solid, the particles are packed tight. Once energy is added however, these particles instantly lose their attraction and move independently, turning it into gas.
How is it possible that liquid nitrogen can boil when it is very cold?
Because it's melting and boiling point is low (it is only cold in relation to us)
Increasing pressure allows particles to boil with less or more energy?
More
How do the particles interact when burning a match?
Chemical bonds are broken, atoms are rearranged, and new bonds are formed.
What the periodic table show?
How atoms combine to form molecules.
