Equal amounts of heat are added to different quantities of copper and lead. The temperature of the copper increases by 5.0oC and the temperature of the lead by 10 oC.
(a) The lead has (1) a greater mass than the copper, (2) the same amount of mass as the copper, (3) less mass than the copper.
(b) Calculate the mass ratio of the lead to the copper to prove your answer to part (a).
