You can use the applet below to **sketch the shape** of the Maxwell-Boltzman energy distribution for the **same molecule** at a **lower** and at a **higher temperature**.

The curves are best drawn as a **series of small lines** as shown in the **diagram on the left**. A maxiumum of **50 discrete lines** are allowed for each curve.

**Step 1**: select the lower temperature of 1000 K and sketch a distribution curve.

**Step 2**: select the higher temperature of 2000 K and sketch a second distribution curve.

**Step 3**: press Analyse for the program to make an analysis of your sketch.

If you have drawn the two distribution curves correctly, the **maximum** for the distribution curve at the **lower temperature** should be at a **lower kinetic energy**, but at a **greater fraction of molecules**, than the maximum for the higher temperature distribution.

The applet **analysis** should help you recognise this feature in your sketching.
