Melting is a process that causes a substance to change from a solid to a liquid. Melting occurs when the molecules of a solid speed up enough that the motion overcomes the attractions so that the molecules can move past each other as a liquid.
The Purpose of Work. âWe work to have leisure, on which happiness depends.â So said Aristotle, quoted by Notre Dame philosopher Gary Gutting to explain âWhat Work Is Forâ in a recent article for The New York Times. Luther countered this medieval view of workâwhich is coming back into style in our consumerist cultureâwith his doctrine of vocation.
Definition Of Work. Work is the transfer of energy. In physics we say that work is done on an object when you transfer energy to that object. If you put energy into an object, then you do work on that object (mass).If a first object is the agent that gives energy to a second object, then the first object does work on the second object.The energy goes from the first object into the second object.f you put energy into an object, then you do work on that object (mass). If a first object is the agent that gives energy to a second object, then the first object does work on the second object. The energy goes from the first object into the second object.
