Solutions

Chapter 2.3, Problem 51E

(a)

To determine

To sketch: The graph of the function E(T)=(5.67×108)T4 for temperature T between 100 K and 300 K.

Expert Solution

Explanation of Solution

The given function is E(T)=(5.67×108)T4 ,

Where,

  • E is the energy radiated per unit of surface area measured in Watts.
  •  T is the absolute temperature in Kelvin.

Use graphing calculator to draw the graph of the Function E with values of T between 100 K and 300 K as shown below in Figure 1.

Figure (1)

From Figure (1), it is noticed that the value of E(T) increases as T increases.

(b)

To determine

To explain: The change in Energy E as the temperature increases.

Expert Solution

Explanation of Solution

From Figure (1), it is clearly visible that the graph rises for all the values of T between 100 K and 300 K. It means that the function E is increasing on the interval (100,300) . Therefore, the energy radiated per unit of surface area increases as the temperature increases.
