Based on what you have learned about the units for measuring thermal energy, complete the following passage. the unit often used in chemistry and physics to measure energy, such as for work or electrical current, is the . we can also use this unit, as we did in this lab, for measuring . this is a property that is quantified by the energy needed per of material to raise the temperature by one . the unit for this measure is therefore . 1 is joule 2 is specific heat 3 is gram 4 degree celsius 5 is j/g'c
