Environmental Engineer Flashcards
Lower than 7PH is BLANK and higher than it is BLANK.
acidic, basic
Higher than normal PH levels can cause BLANK to water and cause mineral build-up on the pipes.
The more BLANK, the more ions, and the better the water will conduct electricity.
saltiness
One way to remove unwanted material is through a process called BLANK.
coagulation
BLANK is produced from enzymes breaking down crops such as wheat or corn. It can be found in alcoholic beverages.
Ethanol
BLANK - As certain types of agricultural waste, like manure, decay, they can release what’s known as biogas. These are gases like methane that can be burned as a source of fuel.
Biomass
BLANK - chemically separate water into hydrogen and oxygen, and just store the hydrogen.
Electrolysis
In BLANK , an atom splits in two, releasing a lot of energy in the process.
fission
BLANK : an extremely hot gas made up of ions, or atoms with an electric charge.
Plasma
A BLANK’s job is to provide a voltage, or energy supply, to push a current through a circuit in the form of negatively charged electrons.
battery’s
Negative terminal
Anode
Positive terminal
Cathode
In BLANK, the cathode absorbs the electrons, which is what makes it the positive terminal in the power supply. Meanwhile, inside the battery, other charges are moving.
reduction
BLANK – another name for disposables.
Primary battery
BLANK – the technical term for the kind that can be recharged.
Secondary batteries
BLANK actually describes a whole class of batteries, but they all tend to have a cathode or anode based on a lithium compound.
Lithium-ion
In engineering terms, a BLANK is a machine designed to interact with its environment, make an appropriate decision based on those surroundings and then carry out the jobs related to its goal, all automatically.
robot
3 Common features in all robots:
BLANK
- Occupy Physical Space
- Sensing features. sensing features of their environment, usually by measuring light, sound, or force feedback.
- Third, to interpret the signals they receive from their environment and coordinate some sort of response, robots have computers built somewhere into their design.
The main mechanical parts used by most industrial robots are called actuators and effectors.
actuators and effectors
BLANK - acts as the robot’s muscles.
Actuators
BLANK, meanwhile are the parts that actually have an effect on the robot’s environment – basically, the robot’s hands. In other words, they give the robot an artificial sense of touch, perhaps with force-sensitive electrodes on the effector’s surface.
