I1-22: WATER DENSITY VS TEMPERATURE

Additional Info

  • ID Code: I1-22
  • Purpose: Demonstrate the change in the density of water with temperature.
  • Description:

    A calibrated thin spherical metal shell with air and shot inside sinks in water at approximately 115-120 degrees F. The water is then cooled by a fan, whereupon the sphere rises to the top of the water when a temperature of about 100-110 degrees F is reached (this cooling can take up to 15 minutes depending on room temperature and humidity).

    The water can be stirred continually to keep the temperature uniform using the digital thermometer probe, which simultaneously reads the temperature, which is displayed on a large scale. If the sphere starts out floating and is sunk by heating the water, the demonstration requires more time due to surface tension.
