Question

In an isolated system, two copper bars at different temperatures transfer energy until both are at the same temperature. How would the transfer of energy be different if the bars were in an open system?
A. Energy transfer would occur only between the copper bars.

B. Energy transfer would occur between the copper bars and the surroundings.

C. No energy transfer would occur between the copper bars or the surroundings.

D. Energy transfer would occur only with the surroundin

Answer 1

Answer is: B. Energy transfer would occur between the copper bars and the surroundings.

Closed system is a physical system that does not allow transfer of mass and energy in or out of the system.

Open system is a physical system that does allow transfer of mass and energy in or out of the system, have input and output flows.

Thermal conductuction is the transfer of heat through physical contact. Thermal conduction is the transfer of heat by microscopic collisions of particles.

Heat spontaneously flows from a hotter to a colder body.
