Presentation transcript:

Temperature

(a) show an appreciation that thermal energy is transferred from a region of higher temperature to a region of lower temperature (b) show an understanding that regions of equal temperature are in thermal equilibrium (c) show an understanding that a physical property that varies with temperature may be used for the measurement of temperature and state examples of such properties (d) compare the relative advantages and disadvantages of resistance and thermocouple thermometers as previously calibrated instruments (e) show an understanding that there is an absolute scale of temperature that does not depend on the property of any particular substance (i.e. the thermodynamic scale and the concept of absolute zero) (f) convert temperatures measured in kelvin

By the end of this lesson you will be able to… Describe the transfer of thermal energy Describe and compare methods for measuring temperature including calibration. Use the absolute temperature scale Convert temperatures from K to oC and oC to K.

Thermometers The Perfect Temperature Sensor: Has no effect on the medium it measures Is precisely accurate Responds instantly (in most cases) Has an easily conditioned output
