| 4A20.00 | Liquid Expansion | | |
| 4A20.10 | Torchelli tube | PIRA 500 | |
| 4A20.10 | Torricelli tube | 4A20.10 | Immerse a Torchelli tube filled with red water in a boiling water bath. The fluid will drop before rising. |
| 4A20.10 | expansion of a tube by heating | Ha-9 | A flask with a long slender neck is filled with colored water and immersed in a hot water bath. |
| 4A20.10 | thermal expansion of water | Disc 14-13 | Fill a round bottomed flask with water, stick a slender tube in the neck, and heat with a burner. |
| 4A20.11 | Torricelli tube | H-32 | A small bulb with a capillary full of mercury is immersed in a bath of hot water. The meniscus falls, then rises. |
| 4A20.12 | Torricelli tube | 25-2.1 | A thermometer inserted in hot water shows a drop in temperature as the glass expands before the liquid warms. |
| 4A20.13 | water thermometer | H-2a.7 | A bulb with a small bore tube. |
| 4A20.20 | expansion of fluids | Ha-12 | A manometer is surrounded on one side with ice water and on the other by steam. |
| 4A20.25 | test tube set | H-27 | A number of test tubes filled with various liquids are immersed in a hot water bath. Expansion is magnified by small bore tubes. |
| 4A20.30 | maximum density of water | PIRA 1000 | |
| 4A20.30 | maximum density of water | H-28 | A flask with a narrow stem shows volume changes and a thermocouple shows temperature changes when water is allowed to warm from 0 C. |
| 4A20.30 | maximum density of water | H-29 | Refinements to H-28. Use a 100 ml quartz flask and 1 mm bore capillary tube for a meniscus drop of 5 to 6 mm. |
| 4A20.30 | negative expansion coefficient of wa | Disc 14-14 | Immerse a water thermometer in an ice bath |
| 4A20.35 | water at 4 C | Ha-13 | Water at the bottom of a cylinder remains at 4 C when surrounded by ice at the middle. |
| 4A20.35 | maxium density of water | H-31 | The familiar Hope apparatus. A tall cylinder of water with a collar of salt/ice around the middle will freeze at the top and remain at 4 C at the bottom. |
| 4A20.35 | maximum density of water | H-30 | In a jar of water 35 cm high with 15 cm of ice floating on top, the temperature at the bottom does not fall below 4 C. |
| 4A20.40 | coefficient of expansion of oil | TPT 2(7),338 | A hydrometer is used to measure the density of olive oil as it cools. |
