Heat energy is due to the movement of atoms or molecules.. As atoms move faster they create more energy = causing Heat!. Thermal Energy. Depends upon the mass, temperature and phase of an object.. On the front counter there is a perpetually thirsty bird. Do NOT touch him.. Write down all your . observations. of the motion. Do not try to explain why it’s happening—just look at WHAT is happening. . Ectotherms. Rely mainly on external energy sources.. Endotherms. - Rely heavily on metabolic energy.

Thermal expansion . – The fluid in a thermometer’s bulb heats up and expands, increasing the volume until it flows up the tube of the thermometer.. Color change. – Some materials change color based on their temperature. Examples are forehead thermometers and mood rings.. Heat. The transfer of thermal energy . Not a measure of energy but rather of energy transferred. . Measured in terms of joules or calories (cal). . Calories relate heat to changes in temperature. . Calorie is defined as the amount of heat needed to raise the temperature of one gram of water by one degree Celsius. . USING THERMAL ENERGY. Thermal Energy. Lesso. n Objectives:. • Explain the relationship between temperature and thermal energy.. • Define heat and specific heat.. Thermal Energy. Lesson Summary:. Heat is the transfer of thermal energy between objects that have different temperatures. . Calculations. Apparent temperature (T. A. ). T. A. = . T. db. + 3.3 * VP + 0.7 * WS – 0.4. With:. T. db. = dry bulb temperature = ambient temperature (°C). VP = water vapour pressure (. hPa. ). In fact, the atmosphere receives very low amount of heat energy from the sun as it receives most of its energy from the long wave terrestrial radiation..
