Laws First Law of Thermo. Second Law of Thermo. Two things happen when energy is transferred from one object to another. Heat is transferred and WORK is done. Not work like sitting in front of the computer doing research, but real work, like lifting and moving things.
Work is linked to the expansion and compression of gases.
When an object heats up, some heat is given off and heats the air around it. That gas expands, and starts things moving around. When scientists measure work the look at the system at the beginning and the end of the project. When everything is said and done they total all the measurements together to figure the total work done. Andrew Rader Studios, All rights reserved.
