Discuss thermometers, absolute temperature, thermal joints inthe bridges, and thermostats in houses.In this discussion question, do not be limited merely by theexamples presented in the discription. Note that the spiritof the question is the explanation in terms of the physics of theweek (thermodynamics) of common day objects and phenomena. Therefore anywhere that there is heat, there is an example toexploit. Car engines, thermal pumps, the human body, and theenvironment are all subject to thermodynamic examination.Be creative with your response! It would be a shame tohave to read about 5 thermometers followed by 6 joints! Picksomething from you daily life: from your career: from your past oryour future. Remember tat the key element here is a physicsbased explanation of the phenomena which involves heat.
