To sketch: The graph of the function for temperature T between 100 K and 300 K.
The given function is ,
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.
From Figure (1), it is noticed that the value of increases as T increases.
To explain: The change in Energy E as the temperature increases.
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 . Therefore, the energy radiated per unit of surface area increases as the temperature increases.
