Question:

Howmuch heat is needed to raise the temperature of a 200g copper bar from 20c to 150c? The specific heat capac

physics

Answer:

HeatQm c Delta(t) Q200 c_of_copper (150-20) c_of_copper The specific heat capac
in ideal conditions it would take 150 c to do it, since the copper would heat to whatever temperature it was exposed to. this could take some time though.
Dear the heat capacity of Copper is 0.1 cal/(g.c) So the heat (H) needed to raise a 200 9 is H mass * specific heat * Delta(t) H (200)(.1)(150-20) 2600 cal H 4.18 * 2600 joule 1086.8 joule
