True False A work done by the system is outflow of energy inflow of energy flow work of energy The law conservation of energy states that energy is neither created nor destroyed, T or F True Falsearrow_forwardWhich of the following statement(s) is(are) correct? Thermal energy with some effort, can only be partially converted to mechanical energy. If a system's work is positive, work is done to the system; work done by the system is negative. N. For a closed system operating adiabatically, work is obtained from the direct conversion of internal energy of the fluid to work. Work or mechanical energy can spontaneously be converted to heat.arrow_forward

During an interaction, energy can change from one form to another but the total amount of energy remains constant. Energy cannot be created or destroyed. The first law is an expression of the conservation of energy principle. B. If two bodies are in thermal equilibrium with a third body, they are also in thermal equilibrium with each other. C. It asserts that energy has quality as well as quantity, and actual processes occur in the direction of decreasing quality of energy.arrow_forwardApplied heat transferarrow_forward
