The first law of thermodynamics states that △E = Q-w. is this also a statement of the principle of conversation of energy? A. The heat that flows into the system is transformed into work and a change in internal energy B. The energy that flows into the system is transformed into heat and work C. The work that is done by the piston is transformed into heat and a change in internal energy D. A change in internal energy causes work to be done and heat to flow into the system

Its A. The heat that flows into the system is transformed into work and a change in internal energy

Answer : The correct option is, (B) The energy that flows into the system is transformed into heat and work.

Explanation :

According to the first law of thermodynamic, the energy cab be transformed from one form of energy to the another form of energy but the energy can neither be created nor be destroyed. It is also called as the law of conservation of energy.

ΔE = Q - W

or,

Q = ΔE + W

where,

E = internal energy

Q = net heat transferred into the system

W = work done by the system or on the system

So, we can say that the heat that flows into the system is transformed into work and a change in internal energy.

Thus, the correct option is, (B)
