(b) How much would the temperature of a 190-kg tree rise if it absorbed the heat released in part (a)? Assume that the specific heat capacity of the ter tree is 3.8 X 105J/(kg . C.) and that no phase change occurs within the 60 tree itself. of 49. E (a) Objects A and B have the same mass of 6.0 kg. They melt when 6.0 x 10* J of heat is added to object A and when 18.0 x 104 J is added to object B. Determine the latent heat of fusion for the substance from which each object is made. (b) Find the heat required to melt object A when its mass is 6.0 kg. 50. E Find the mass of water that vaporizes when 3.20 kg of mercury at 265 .C is added to 0.2110 kg of water at 90.0 .C. 51. E A mass m = 0.074 kg of benzene vapor at its boiling point of 80.1 .C is to be condensed by mixing the vapor with water at 52 C. What is the minimum mass of water required to condense all of the benzene vapor? Assume that the mixing and condensation take place in a perfectly insulating container. 52. E A certain quantity of steam has a temperature of 100.0 .C. To convert this steam into ice at 0.0 C, energy in the form of heat must be removed from the steam. If this amount of energy were used to accelerate
