4B10.15 | water and oil | 4B10.15 | Heat two beakers on a single hot plate, each contains the same mass of either water or oil. |
4B10.16 | iron and water | H-35 | Iron and a vessel of water with the same mass and area are heated on identical Bunsen burners. Dip your hand in the water and sprinkle it on the iron plate where it will sizzle. |
4B10.20 | mixing water | H-39 | Different masses of hot and cold water are mixed in a large beaker and the final temp is compared to the calculated value. |
4B10.26 | calorimeter | Hb-1 | A calorimeter is used to measure the specific heat of lead. |
4B10.26 | hot lead into water | H-40 | Known masses of lead and copper are heated and poured into calorimeters with a known mass of water. Specific heats are computed from initial and final temperatures. |
4B10.27 | ice calorimeter | H-38 | Several different metals on the same mass are heated to the same temp and lowered into a line of crushed ice filled funnels. The melted water is collected in graduates. |

4B10.40 | differential thermoscope | H-41 | The jacket areas of two unsilvered unevacuated dewar flasks are connected to a U tube and equal masses of water and mercury at 100 C are poured in. The U tube shows the difference in heat capacities. |

4B10.55 | specific heat of a gas | AJP 33(1),18 | Heat a gas in a flask by discharging a capacitor through a thin constantan wire and measure the momentary increase in pressure on an attached water manometer. |
4B10.60 | Clement's and Desormes' experiment | PIRA 1000 | |
4B10.60 | Clement's and Desormes' experiment | 4B10.60 | A 10 L flask fitted with a mercury manometer is over pressured and then the valve is quickly opened and shut. The ratio of pressures is related to the specific heats. |
4B10.60 | Clement's and Desormes' experiment | Hg-3 | A large flask with an attached mercury manometer is overpressured and momentarily opened to the atmosphere. |
4B10.61 | comment on Cp/Cv with manometer | AJP 35(9),892 | Recommendation of an alternative statement of the problem and results. |
4B10.61 | Cp/Cv with water manometer | AJP 35(4),xvi | Replace the mercury in the oscillating column method with water provided the confined air is a large volume. |
4B10.65 | elastic properties of gases | 4B10.65 | A steel ball in a precision tube oscillates as gas escapes from a slightly overpressured flask. |

4B10.70 | elastic properties of gases | PIRA 1000 | |
4B10.70 | Ruchhardt's method for gamma | AJP 32(1),xiii | An ordinary glass tube is selected with a slight taper wider at the top. A throttle valve controls the inlet pressure and the oscillations of the ball in the tube are timed. |
4B10.70 | Ruchhardt's method for gamma | 27-6.5 | A ball oscillates in the neck of a flask filled with gas. The pressure is measured indirectly as the ball oscillates. |
4B10.72 | Ruchhardt's method - add mass | AJP 32(4),xvi | Add additional mass to the oscillating ball and plot period as a function of mass. |
4B10.72 | Ruchhardt's method for gamma | 27-6.6 | Ruchhardt's apparatus is driven by a slow flow of gas and the ball is loaded with additional mass. |
4B10.73 | syringe Ruchhardt's experiment | AJP 53(7),696 | A glass syringe replaces the precision ball in a precision tube and an accelerometer mounted on the syringe allows the oscillations to be displayed on an oscilloscope. |
