EGEE 101 Exam 2025 Questions and
Answers
Radiation - Correct Answer✔️✔️-how the "warmth" of the sun is transferred to you when you're
out or how you warm your hands in front of the fire.
- it can travel through space
Convection - Correct Answer✔️✔️-how the water becomes hot
-The water molecules are free to roam about as they are not fixed in relative positions (unless
frozen) like the metal atoms.
-So as a water molecule heats up it has more energy and travels further.
-The molecules moving around have lots of collisions but this molecular billiards occurs without
energy loss and so they will keep on colliding until there is a distribution of energy.
heat pump - Correct Answer✔️✔️-a device that moves heat
heat flows from... - Correct Answer✔️✔️-hot to cold
compressor - Correct Answer✔️✔️-pressurize the gas so the heat is concentrated and thus the heat
exchange will be more efficient

, - cools the gas down so it will turn back into a liquid
Solar Energy Extractions - Correct Answer✔️✔️-- directly taking solar energy from the sun
1) Photovoltaic
2) 2 Thermal Systems
* Reflecting mirrors
* Parabolic mirrors
Thermal System - Correct Answer✔️✔️-- concentrating solar rays onto a boiler or focal point w/
oil flowing through and heat oil up
- heat transfer process produces steam and steam produces electricity
Photovoltaic - Correct Answer✔️✔️-- energy from sun is in small packages (photon)
- put photon w/ a positive and negative electron
- electron makes connection
Typically as coal gets older what happens... - Correct Answer✔️✔️-1) The rank of the coal
increases
2) Decrease in the moisture content
3) Increase in the carbon content
List fossil fuels - Correct Answer✔️✔️-1) Oil
2) Coal
