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 examine how vapor pressure is calculated. The vapor pressure of a liquid increases with increasing temperature. If the heat of vaporization and the vapor pressure at one temperature are known, the vapor pressure at a second temperature can be calculated.

Learners examine how a radiation pyrometer converts the frequency of electromagnetic waves to a temperature reading.

Learners study the process of mathematically converting temperatures between the Fahrenheit and Celsius scales.

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.

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 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.

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.

In this animated object, learners examine why and when the Kelvin scale is used. A brief quiz completes the activity.

In this animated object, learners examine the operation of a temperature alarm circuit that uses a thermistor in a Wheatstone Bridge.

Learners examine the fundamental operation of a difference operational amplifier. A brief quiz completes the activity.

In this learning activity you'll factor problems using the difference of two perfect squares.

In this animated object, learners examine the relationship between pressure and temperature in an air conditioning system.

Learners observe how an optical pyrometer is used to take temperature measurements without making physical contact with the object being measured.

In this animated object, learners observe the operation of a J thermocouple with a cold junction. A table is used to convert the voltage it produces to a corresponding temperature. A brief quiz completes the activity.

Learners study the theory of operation for a ratio pyrometer that measures temperature. A short quiz completes the activity.

In this learning activity you'll calculate problems using the negative both inside and outside of the parenthesis.

In this animated activity, learners explore three major methods of heat transfer and practice identifying each.

Learners examine the electronic components of a digital thermometer.

Learners view an animation showing how the volume of a given quantity of gas varies directly with its temperature.
