A reversible engine works between between two
temperatures whose difference is 100°C. If it
absorbs 746 J of heat from the source and rejects
546 J to the sink, calculate the temperature of the
source and the sink.
A) 100°C, 20°C
B) 100°C, 0°C
C) 80°C, 0°C
D) 80°C, 20°C

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.

it would be c. predictability
