4B10.05specific heat of liquids problemAJP 52(9),856A note on the inexplicably high specific heat of liquids.
4B10.10water and aluminum on a hot platePIRA 500
4B10.10water and aluminum on the hot plate4B10.10One liter of water in a beaker water and aluminum of 1 Kg total mass in another beaker are heated on the same hot plate. Display temperatures of both.
4B10.10heat capacityHb-2Two beakers, one with 1 Kg water and the other with .5 Kg water and .5 Kg lead are heated at the same rate.
4B10.10specific heatDisc 14-17Heat lead, aluminum, and steel to 100 C and then warm cool water. Show temp on LED bar graph.
4B10.15water and oil on a hot platePIRA 1000
4B10.15water and oil4B10.15Heat two beakers on a single hot plate, each contains the same mass of either water or oil.
4B10.16iron and waterH-35Iron 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.
4B10.20mixing waterH-39Different masses of hot and cold water are mixed in a large beaker and the final temp is compared to the calculated value.
4B10.26calorimeterHb-1A calorimeter is used to measure the specific heat of lead.
4B10.26hot lead into waterH-40Known 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.
4B10.27ice calorimeterH-38Several 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.
4B10.28metals in waterH-37Heat metals of the same mass and lower them into beakers containing the same amount of water at room temperature.
4B10.30melting waxPIRA 1000
4B10.30melting wax4B10.30Five metals of the came mass are heated in boiling water and placed on a thin sheet of paraffin.
4B10.30melting waxH-36Several cylinders of the same metals with the same mass and diameter are heated in paraffin and transferred to a paraffin disc.
4B10.30specific heat with rods and waxDisc 14-18Heat equal mass cylinders of aluminum, steel, and lead and let them melt a path through honeycomb.
4B10.35specific heat at low temperatures26-2.1Cylinders of the same size of aluminum and lead heat up at the same rate after being cooled in liquid nitrogen.
4B10.40differential thermoscopeH-41The 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.
4B10.50heat of combustionH-42A bomb or continuous flow calorimeter is used to show heating value of foods and fuel.
4B10.55specific heat of a gasAJP 33(1),18Heat 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.
4B10.60Clement's and Desormes' experimentPIRA 1000
4B10.60Clement's and Desormes' experiment4B10.60A 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.
4B10.60Clement's and Desormes' experimentHg-3A large flask with an attached mercury manometer is overpressured and momentarily opened to the atmosphere.
4B10.61comment on Cp/Cv with manometerAJP 35(9),892Recommendation of an alternative statement of the problem and results.
4B10.61Cp/Cv with water manometerAJP 35(4),xviReplace the mercury in the oscillating column method with water provided the confined air is a large volume.
4B10.65elastic properties of gases4B10.65A steel ball in a precision tube oscillates as gas escapes from a slightly overpressured flask.
4B10.65elastic properties of gasesHg-4Gas escapes from a flask through a precision tube with a precision ball oscillator.
4B10.70elastic properties of gasesPIRA 1000
4B10.70Ruchhardt's method for gammaAJP 32(1),xiiiAn 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.
4B10.70Ruchhardt's method for gamma27-6.5A ball oscillates in the neck of a flask filled with gas. The pressure is measured indirectly as the ball oscillates.
4B10.72Ruchhardt's method - add massAJP 32(4),xviAdd additional mass to the oscillating ball and plot period as a function of mass.
4B10.72Ruchhardt's method for gamma27-6.6Ruchhardt's apparatus is driven by a slow flow of gas and the ball is loaded with additional mass.
4B10.73syringe Ruchhardt's experimentAJP 53(7),696A 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.
4B10.75Ruchhardt's experimentHg-5Measure the temperature in the flask with the oscillating balls.
