Notes:
When a beaker of water containing a thermometer is heated over a flame, the rapidly moving gas particles in the flame transfer kinetic energy to the atoms in the glass beaker, which vibrate faster and transfer kinetic energy to the molecules of water. The faster-moving water molecules collide more energetically with the atoms in the thermometer bulb, which in turn transfer kinetic energy to the atoms of mercury, causing the mercury to rise.
