1st law of Thermodynamics |
IF the mechanical energy of a system is constant, the increases in thermal energy of that system equals the sum of the thermal energy transfer into that system and the work done on that system |
|
|
2nd law of Thermodynamics |
Energy spontaneously spreads from reasons of higher concentration to regions of lower concentration |
|
|
Thermodynamics |
The study of the relationships between thermal energy ,heat,and work |
|
|
Distillation |
the action of purifying a liquid by a process of heating and cooling. |
|
|
Electron Dot Diagram |
Use chemical Symbol of a element surrounded by dots to represent the number of electron in the atom |
|
|
Nuclear Reactor |
uses energy from controlled nuclear reactive to generate electricity |
|
|
Petroleum |
Flammable liquid formed from the decay of ancient organism such as a microscopic plankton/algae |
|
|
Geothermal Energy |
Thermal energy that is contained in and around magma |
|
|
Frequency |
Number of wavelength that pass a fixed point each sound |
|
|
Medium |
Matter through which a wave travels |
|
|
Isotope |
each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties; in particular, a radioactive form of an element.
|
|
|
Allotrope |
each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties; in particular, a radioactive form of an element.
|
|
|
Heterogeneous Mixture |
mixture in which different materials remain distinct |
|
|
Homogeneous mixture |
Mixture that remains constantly and unfailingly mixed and has particles so big, they cant be seen by microscope |
|
|
Charles law |
at constant pressure the volume of a gas increases as the temperature increases |
|
|
Boyle's law |
Constant temperature, a change in volume results in the pressure on the container |

What is Buoyancy? |
The ability or tendency to float in water or air or some other fluid.
|
|
|
Law of conservation of energy |
Energy can cannot be created or destroyed |
|
|
Group |
The column up and down |
|
|
perioid |
The column to the sides |

|
What is a colloid |
Heterogeneous mixture with particles that never settle |
|
|
how do you know how many newtons an element has? |
Atomic mass divided by Atomic Number |
|
|
How can you tell how many protons an element has |

|
|
What are the three types of subatomic particles |
Protons and newtons and electrons |
