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 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.
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.
Conifers are well adapted to living in the cold. Because needles are retained for two to 15 years, they can begin photosynthesis in spring as soon as temperatures are warm enough.
