Lesson 1 Vocab
This type of energy is the energy an object has due to its motion.
What is kinetic energy?
A change from a liquid or solid state to a gas state is called this.
What is vaporization?
Combining 1 atom of oxygen and 2 atoms of hydrogen yields this substance.
What is water (H2O)?
This occurs when matter changes state when it gains or loses enough thermal energy.
What is melting?
A bowl of hot soup transfers this to your hands as well as the air above when removed from the microwave.
What is thermal energy?
This gives you the measure of the average kinetic energy of the particles in a material.
What is temperature?
This only occurs at the surface of a liquid.
What is evaporation?
This state of matter can be compressed.
What is gas?
This is the result of a solid converting to a gas while avoiding the liquid state.
What is sublimation?
There are two types of energy a particle can have.
What are kinetic energy and potential energy?
This type of energy is stored energy due to the interaction between particles or objects.
What is potential energy?
You get this when an amount of force per unit area is applied to an object' surface.
What is pressure?
The element ratio of this compound include 40% hydrogen, 40% oxygen and 20% magnesium.
What is 2:2:1?
This is the result of a gas converting to a solid while bypassing the liquid state.
What is deposition?
H2O2 is an example of this.
What is chemical formula?
Atoms make these up. It's matter with a composition that is always the same.
What is a substance?
Transferring thermal energy from a region of higher temperature to a region of lower temperature gives you this.
What is heat?
The particles that make up this state of matter are very close to one another in a rigid structure.
What is a solid?
This is the opposite of melting.
What is freezing?
The structure of this substance tells me that for every one atom of carbon, there are twice as many atoms of oxygen.
What is CO2 (carbon dioxide)?
This is the building block of matter.
What is an atom?
You get this when volume decreases as its temperature decreases.
What is thermal contraction?
The symbol for this element is Au.
What is gold?
Charle's law states that the volume of a gas increases with increasing temperature.
What is volume-temperature law?
This idea describes how water moves from oceans to the atmosphere.
What is evaporation?
