Energy and Transformations
The ability to do work
What is energy?
Temperature is described as the average this of particles.
What is kinetic energy?
a pure substance that CAN NOT BE BROKEN DOWN; into simpler substances.
What is an element?
Joe drinks lemonade, eats wheat thins, and jumps on a trampoline, somersaulting through the air. This is the liquid in the previous sentence.
What is lemonade?
This describes all the light we can and cannot see.
What is the electromagnetic spectrum?
A push or a pull on an object
What is force?
Heat transfers this.
What is thermal energy?
two or more types of elements; that are "CHEMICALLY" combined.
What is a compound?
An airlike fluid substance which expands freely to fill any space available, irrespective of its quantity.
What is a gas?
This refers to electromagnetic radiation of any wavelength, whether visible or not OR electromagnetic radiation, particularly radiation of a wavelength that is visible to the human eye.
What is light?
When a battery charges your phone, this kind of energy transformation occurs
What is chemical potential to electrical to chemical potential?
Adding heat to a liquid could cause this change.
What is evaporation?
Two or more pure substances combined together
What is a mixture?
This has particles that are more densely packed than other phases of matter.
What is a solid?
A wave of compression and rarefaction, by which sound is propagated in an elastic medium such as air.
What are sound waves?
If you throw a mouse into the air, it has the most gravitational potential energy at this point.
What is at the highest point?
Removing heat from a gas could cause this change.
What is condensation (or deposition)?
Give an example of a mixture
Answers may vary
In this phase of matter, particles can jiggle back and forth but not change places.
What is a solid?
These waves compress and rarify the medium they move through.
What are compression waves?
This happens to energy when a gas becomes a liquid.
What is releases?
How are elements, compounds, and mixtures related to one another?
All are made of atoms. Elements are one type of atom, compounds are two or more elements chemically combined, and mixtures are two or more elements or compounds in the same area.
This is the smallest unit of matter in chemistry.
What is an atom?
This part of a wave describes the distance from one wave to the same point on the next wave.
What is the wavelength?
