Answer 1

Question

Chapter 15, Problem 1FC

To determine

What positive value of Q and positive value of W represents in the first law of thermodynamics.

Expert Solution & Answer

Answer to Problem 1FC

Positive value of Q represents the (c) system gains heat and positive value of W represents the work is done by the system.

Explanation of Solution

The expression of the first law of thermodynamics is,

ΔU=Uf−Ui=Q−W

Whenever the system gains the heat, the value of Q is positive. Similarly, the value of Q is negative whenever the system loses the heat.

If the work is done by the system, the value of W is positive. Similarly, the value of W is negative when the work is done on the system.

Conclusion:

Hence, the positive value of Q represents the (c) system gains heat and positive value of W represents the work is done by the system.

Students have asked these similar questions

A capacitor with a capacitance of C = 5.95×10−5 F is charged by connecting it to a 12.5 −V battery. The capacitor is then disconnected from the battery and connected across an inductor with an inductance of L = 1.55 H . At the time 2.35×10−2 s after the connection to the inductor is made, what is the current in the inductor? At that time, how much electrical energy is stored in the inductor?

Can someone help me with this question. Thanks.
