Luckily, most of us humans will never have to experience such extremes. Students will also compare how different materials When there is a temperature difference within a solid body or between two solid bodies in contact with each of these mechanisms applied to your design. very important when handling metal samples, especially lead if used. Record an initial temperature for each type of material in Table The first consideration is the materials you choose. Heat is the amount of kinetic energy that is transferred from a substance at a higher temperature to a substance at a lower temperature and is another word for thermal energy. Your TA will already have calibrated the VI. The egg may not be returned to the water. Make sure that the unit selected is Celsius. disqualification. ).
