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

An object is placed 24.1 cm to the left of a diverging lens (f = -6.51 cm). A concave mirror (f= 14.8 cm) is placed 30.2 cm to the right of the lens to form an image of the first image formed by the lens. Find the final image distance, measured relative to the mirror. (b) Is the final image real or virtual? (c) Is the final image upright or inverted with respect to the original object?

Concept Simulation 26.4 provides the option of exploring the ray diagram that applies to this problem. The distance between an object and its image formed by a diverging lens is 5.90 cm. The focal length of the lens is -2.60 cm. Find (a) the image distance and (b) the object distance.
