4E10.11Galileo's thermometerH-3An inverted flask with a long slender stem is set in water. As the air in the flask cools, the water in the tube rises.
4E10.11thermal expansion of airDisc 14-12Hold the inverted flask of Galileo's thermometer with the hands to heat the entrained air and force the water in the tube down.
4E10.12capillary tube thermometer25-2.8A capillary tube with a bead on mercury is sealed at one end.
4E10.12horizontal thermometerH-4An air filled flask fitted with a long slender tube is held horizontally and a small globule of mercury moves in the tube as the air in the flask changes temperature.
4E10.13gas thermometer25-2.4A gas thermometer operated at reduced pressure.
4E10.14air thermometerH-2a.3Just an unclear picture - might be a balloon on a flask.
4E10.15change of volume with change of tempHk-2A flask with a balloon fitted on the neck is heated with hot water and immersed in dry ice/alcohol.
4E10.15balloon on a flask27-2.7A balloon on the neck of a large flask changes volume when the flask is placed into hot water or dry ice/alcohol.
4E10.16expansion of gassesH-34Two identical constant pressure gas thermometers are filled with different gasses and immersed in a water bath to show the same volume increase.
4E10.16expansion of gassesH-33Two bulbs connected by a "U" tube manometer are filled with different gasses and heated the same amount by immersing in a water bath to show pressure increase is the same on both sides.
4E10.20balloons in liquid nitrogenPIRA 200Pour liquid nitrogen over an air filled balloon until it collapses and then let it warm up again.

4E10.21balloon in liquid nitrogen27-2.8A balloon partially inflated on the end of a glass rod is immersed in liquid nitrogen.
4E10.22balloons in liquid nitrogenAJP 39(7),844Cool balloons filled with Carbon dioxide, argon, helium, pass them around the class.
4E10.30air pressure at low temperatureH-98Immerse the bulb of a small thermoscope in liquid air.
