Inquiry-Oriented Student Performance Objectives:
9.1 Temperature
- Students will, using corresponding temperatures and graphical analysis,
determine the relationship between Celsius and Fahrenheit temperature scales.
- Students will, using a constant volume thermometer, liquid nitrogen, hot
water, etc., determine the Celsius temperature of absolute zero.
- Students will, using an immersion heater in a cup of water as well as voltmeter
and ampmeter, determine the electrical equivalent of heat.
- Students will, using a drop tube filled with lead shot, determine the mechanical
equivalent of heat.
- Students will, using an appropriate apparatus, determine the mechanical
equivalent of heat.
- Students will, using suitable temperature sensors and data recording instruments,
verify Newton’s law of heating/cooling.
- Students will, using a thermocouple, determine the relationship between
the electromotive force and the temperature differences of the junctions (Seebeck
effect).
9.2 Thermal Expansion
- Students will, using heat and appropriate measuring devices, determine
the coefficient of linear expansion for a known metal.
- Students will, using an inverted “fountain” (inverted, stoppered,
steam-filled flask with tube extending downward into water), determine the
change in volume of steam as it condenses back into liquid form.
9.3 Specific and Latent Heat
- Students will, using the method of mixtures, determine the specific heats
of various metals.
- Students will, using an immersion heater, determine the heat of vaporization
for liquid nitrogen.
- Students will, using ice, water, and the method of mixtures, determine
the heat of fusion of ice.
- Students will, using ice and an in-frozen immersion heater, determine the
heat of fusion of ice.
9.4 Heat Transfer
-
Students will,
9.5 Thermodynamics
- Students will, using an ideal Carnot engine and appropriate measuring devices,
trace out adiabatic and isothermal contours on a graph.
