create js applet the display a box with random dots that represent molecules and a slider that represent temperature that can be controlled by the user. changing the slider increase the temperature which display as dots shaking more rapidly and change color from blue to red
  Sure! Here is an example of a simple JavaScript applet that displays a box with random dots that represent molecules and a slider that represents temperature:
```
<!DOCTYPE html>
<html>
  <head>
    <meta charset="UTF-8">
    <title>Molecule Simulator</title>
    <style>
      #molecule-box {
        position: relative;
        width: 500px;
        height: 500px;
        border: 1px solid black;
        background-color: #f0f0f0;
      }
     .molecule {
        position: absolute;
        width: 10px;
        height: 10px;
        border-radius: 50%;
        background-color: #333;
        animation: move 3s infinite linear;
      }
      @keyframes move {
        from {
          transform: translate(0, 0);
        }
        to {
          transform: translate(random(0), random(0));
        }
      }
    </style>
  </head>
  <body>
    <div id="molecule-box">
      <div class="molecule"></div>
     
<html>
  <head>
    <title>Molecules</title>
  </head>
  <body>
    <applet code="Molecules.class" width=400 height=400>
    </applet>
