Learners view illustrations showing the direct dependence of the volume of a gas on temperature and consider the relationship between the Kelvin and Celsius temperature scales.
Dietary Manager Training: Cooling Foods by Reducing the Quantity or Size of the Food
In this animated lesson, students read how reducing the thickness of a food is an important factor in cooling it. They also read FDA guidelines for food temperatures.
Learners read how they can make menus more pleasing to the senses by paying attention to shape, form, texture, temperature, color, flavor, and visual appeal.
Boyle's Law states that gas volume varies inversely with the pressure at constant temperature and is described by the equation PV = constant. An example of a sample of gas at two conditions of P and V is used to illustrate the law.
In this animated object, learners examine how gas volume varies directly with absolute temperature (K at constant pressure). An example of a sample of gas at two conditions of volume and temperature is used to illustrate the law.
Learners study the effect that pressure has on boiling temperatures. Once a liquid has reached a full boil, additional heat does not raise the liquid’s temperature; however, pressure can vary the boiling point of a liquid. A brief quiz completes the activity.
Learners observe that the melting of a solid and the freezing of its liquid occur at the same temperature. The melting point is an intrinsic property and is used to identify a substance.
Learners study animations to see the connection between temperature and resistance as they examine the operation of an RTD. A table is used to convert resistance readings to the corresponding temperatures. A brief quiz completes the activity.
Learners observe that the volume of one mole of any gas is 22.4 L at standard temperature and pressure. An illustration shows that only the mass of the molar volume differs with the identity of the gas.
Temperature Emissivity of Non-Blackbodies (Screencast)
Learners study the effect of reflected and transmitted energy on the measurement of emitted energy by a non-blackbody. A short quiz completes the activity.
