Question

An egg, initially at rest, is dropped onto a concrete surface and breaks. With the egg treated as the system:

a) What is the sign of W?
b)What is the sign of ?Ep?
c) what is ?Ek?
d) what is ?Ut?
e) what is the sign of Q?
In modeling this process, assume the passage of sufficient time for the broken egg to return to its initial temperature. What is the origin of the heat transfer of part (e)?

Answer 1

a) Negative
b) Negative
c) Positive
d) 0
e) Positive

The origin of heat transfer is the conversion of potential energy of the egg to heat energy.
