Cunningham; Mary Ann Cunningham), Business Law: Text and Cases (Kenneth W. Clarkson; Roger LeRoy Miller; Frank B. Design tab. Note that the difference in degrees between the freezing and boiling points is greater for the Fahrenheit scale than for the Celsius scale. surroundings by an imaginary boundary. This is because the amount of mass affects an object's ability to absorb thermal energy. Thermometers are devices used to measure temperature or a temperature gradient utilizing a temperature sensor and some other means to convert the physical change to a digital change. If you wanted, you could create your own temperature scale! This is because each substance has its own specific heat. Another thing to consider is the method of data collection, because the way data is collected can cause many issues including providing incorrect data. Thermistors are thermally sensitive resistors that display changes in electrical resistance when subjected to a temperature change. 1.8: Experiment 7 - Precipitation.
