Derive a control volume form of the second law of thermo-dynamics. Suggest some practical uses for your relation in analyzing real fluid flows.

Restate the first two laws of thermodynamics in your own words.

In your own words, state the first and second laws of thermodynamics.

Describe the first and second laws of thermodynamics.

A glass tube is closed at one end. The air column it contains has a length that can be varied between 0.50 m and 1.50 m. A tuning fork of frequency 306 Hz is sounded at the top of the tube. Predict the lengths of the air column at which loud sounds would be heard from the tube. (Take the speed of sound to be

$$340 \mathrm { ms } ^ { - 1 }$$

.)

An air-standard Diesel cycle has a maximum temperature of 1800 K. At the beginning of compression, $p_1 = 95 kPa$ and $T_1 = 300 K.$ The mass of air is 12 g. For compression ratios ranging from 15 to 25, plot a. the net work of the cycle, in kJ. b. the thermal efficiency. c. the mean effective pressure, in kPa.

Use a graphing utility to graph the equation. Use the trace feature of the graphing utility to approximate the unknown coordinate of each solution point accurate to two decimal places. (Hint: You may need to use the zoom feature of the graphing utility to obtain the required accuracy.) $y=\sqrt{5-x}$ (a) (3, y). (b) (x, 3)

What is a basic requirement that a scientific hypothesis must have?

A baseball is thrown from the upper deck of a stadium 128 ft above the ground. The function

$$h(t) = - 16t^2 + 32t + 128$$

gives the height of the ball t seconds after it is thrown. How long will it take the ball to reach the ground?

Why would you expect glucose storage as glycogen to be an energy-requiring process?

In the postabsorptive state, glycogen is hydrolyzed to liberate glucose. This process is called _____.

The process of converting excess glucose to glycogen in the liver and muscle is referred to as __________.

Supply the missing term.

In the postabsorptive state, glycogen is hydrolyzed to liberate glucose. This process is called ___________.

$\rule{2cm}{1pt}$ is the conversion of glucose into glycogen. $\rule{2cm}{1pt}$ is the conversion of glycogen into glucose. $\rule{2cm}{1pt}$ is the conversion of amino acids into glucose.
