A student found an unknown substance. In an effort to identify the thermal properties of the substance, she isolated a specimen of 47 gram, and applied 290 J of heat energy to the specimen. If she measured the temperature of the specimen changed from 20 ° C to 25.7 ° C, what is the specific heat of the unknown substance?

How exactly do I do that?

  • AP Physics -

    Specific heat =

    =(heat added)/[temperature change)*mass)]

    = 290 J/[5.7 C *47 g] = 1.082 J/(C g)
