Intro to Physics: Chapter 7.3 & 7.4 – What is Heat & Heat Transfer Before reading: Examine the statements below and indicate whether you agree or disagree with each one. Statement Agree Disagree 1.) The amount of thermal energy an object has depends on its temperature & the amount of matter in it. 2.) Heat flows naturally from a colder object to a warmer one. 3.) The metric unit for measuring heat is the degree. 4.) If an object’s specific heat is low, its temperature will change relatively quickly, & if an object’s specific heat is high, its temperature will change relatively slowly. 5.) In general, materials made up of heavy atoms or molecules have high specific heat compared with materials made up of lighter ones. 6.) Conduction only occurs between two materials at different temperatures & when they are touching each other. 7.) Thermal equinox occurs when two bodies have the same temperature & no heat flows. 8.) Conduction happens only if there are particles available to collide with one another, so it cannot occur in the vacuum of space. 9.) Convection is the transfer of heat through the motion of fluids such as air & water. 10.) Thermal radiation cannot travel through the vacuum of space. After reading: Reexamine your responses to the statements. Rewrite each statement below, correcting those that are incorrect. Write the page number where the correct information can be found in the text. Corrected Statement . Page # 1.) p. 2.) p. 3.) p. 4.) p. 5.) p. 6.) p. 7.) p. 8.) p. 9.) p. 10.) p.
