| 4C31.00 | Cooling by Evaporation | | |
| 4C31.10 | cryophorous | PIRA 500 | |
| 4C31.10 | cryophorous | 4C31.10 | One end of an evacuated glass tube with bulbs at each end is put in liquid nitrogen, water in the other end will freeze. |
| 4C31.10 | cryophorous | Hj-8 | One end of a tube is stuck in a cold trap and water in the other end freezes. |
| 4C31.10 | cryophorous | H-67 | Water in one end of an evacuated J tube will freeze when the other is placed in a ice-salt mixture, alcohol-dry ice mixture, or liquid air. |
| 4C31.10 | cryophorus | Disc 15-14 | Place a cryophorus in liquid nitrogen. |
| 4C31.11 | cryophorous | H-68 | Water in an evacuated sealed flask with a concave bottom freezes when it is inverted and a dry ice/alcohol mixture is placed in the concavity. |
| 4C31.12 | cryophorous | 26-5.10 | A Lucite assembly for the overhead projector with an evacuated chamber holding water and an area for a dry ice/acetone mixture. |
| 4C31.20 | freezing by evaporation | PIRA 1000 | |
| 4C31.20 | freezing by evaporation | AJP 32(11),xxii | Evacuate a chamber with water on the overheard between crossed Polaroids. |
| 4C31.20 | freezing by evaporation | AJP 35(9),x | For the overhead projector: make a hole for a small thermometer in the bottom of a small test tube and pump on a small amount of water. |
| 4C31.20 | freezing by evaporation | 26-5.9 | Pump down some distilled water in a chamber on an overhead projector until the water freezes. Crossed Polaroids make the effect more visible. |
| 4C31.20 | freezing by boiling | Disc 15-13 | Evacuate a chamber containing a small amount of water. |
| 4C31.21 | freezing by evaporation | H-70 | Freeze water in a watch glass over a dish of sulfuric acid in a bell jar. |
| 4C31.22 | freezing by evaporation | H-69 | Freeze water in a flask by pumping through a sulfuric acid trap. Supercooling up to 10 C is possible. |
| 4C31.30 | drinking bird | PIRA 200 | Cooling causes vapor to condense, lowering the center of gravity until the bird tips, raising the c. of g. |
| 4C31.30 | drinking bird | 4C31.30 | The drinking bird has a wet head which evaporates drawing liquid up his neck and tipping him over. |
| 4C31.30 | drinking bird | Hj-7 | Cooling causes vapor to condense lowering the center of gravity until the bird tips. |
| 4C31.30 | drinking bird | Disc 15-12 | Standard drinking bird. Includes animation. |
| 4C31.31 | CO2 cartridge cools | H-66 | Puncture a CO2 cartridge and the steel bulb will cool enough to form frost but there is not enough gas to produce snow. |
| 4C31.32 | evaporating carbon disulfide | H-64 | Evaporating carbon disulfide (highly inflammable and poisonous) is used to form frost. |
| 4C31.33 | evaporating ether | H-63 | Evaporating ether in a watch glass freezes a drop of water between the bottom of the glass and a cork. A method for burning off the ether is shown. Diagram. |
| 4C31.34 | evaporating ethyl chloride | H-62 | Ethyl chloride is used to freeze water in a small dish or cool a thermometer. |
| 4C31.35 | cooling by evaporation | 26-5.5 | An attached manometer shows cooling when several drops of ether are placed in a flask. |
| 4C31.37 | pulse-glass engine | H-73 | A pulse glass will oscillate when mounted in a stirrup so one side and then the other can contact a cool pad. |
