Environmental Engineer

Question 1

Lower than 7PH is BLANK and higher than it is BLANK.

Answer 1

acidic, basic

Question 2

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.

Answer 2

saltiness

Question 3

One way to remove unwanted material is through a process called BLANK.

Answer 3

coagulation

Question 4

BLANK is produced from enzymes breaking down crops such as wheat or corn. It can be found in alcoholic beverages.

Answer 4

Ethanol

Question 5

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.

Answer 5

Biomass

Question 6

BLANK - chemically separate water into hydrogen and oxygen, and just store the hydrogen.

Answer 6

Electrolysis

Question 7

In BLANK , an atom splits in two, releasing a lot of energy in the process.

Answer 7

fission

Question 8

BLANK : an extremely hot gas made up of ions, or atoms with an electric charge.

Answer 8

Plasma

Question 9

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.

Answer 9

battery’s

Question 10

Negative terminal

Answer 10

Anode

Question 11

Positive terminal

Answer 11

Cathode

Question 12

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.

Answer 12

reduction

Question 13

BLANK – another name for disposables.

Answer 13

Primary battery

Question 14

BLANK – the technical term for the kind that can be recharged.

Answer 14

Secondary batteries

Question 15

BLANK actually describes a whole class of batteries, but they all tend to have a cathode or anode based on a lithium compound.

Answer 15

Lithium-ion

Question 16

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.

Answer 16

robot

Question 17

3 Common features in all robots:

BLANK

Answer 17

1. Occupy Physical Space
2. Sensing features. sensing features of their environment, usually by measuring light, sound, or force feedback.
3. Third, to interpret the signals they receive from their environment and coordinate some sort of response, robots have computers built somewhere into their design.

Question 18

The main mechanical parts used by most industrial robots are called actuators and effectors.

Answer 18

actuators and effectors

Question 19

BLANK - acts as the robot’s muscles.

Answer 19

Actuators

Question 20

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.

Answer 20

Effectors
