Solution: Two solids of equal mass, labeled X and Y, are placed in contact with each other. Solid X  has an initial temperature of 100°C and  Solid Y has an initial temperature of 25°C. After some time, both solids are at 40°C. Which statement is correct regarding the direction of heat transfer and specific heat capacity (Assume heat transfers only between X and Y):   Direction of heat transfer                       Specific heat capacity A.                From X to Y                                          X has greater heat capacity B.                From X to Y                                          Y has greater heat capacity C.                From Y to X                                          X has greater heat capacity D.                From Y to X                                          Y has greater heat capacity

Problem

Two solids of equal mass, labeled X and Y, are placed in contact with each other. Solid X  has an initial temperature of 100°C and  Solid Y has an initial temperature of 25°C. After some time, both solids are at 40°C. Which statement is correct regarding the direction of heat transfer and specific heat capacity (Assume heat transfers only between X and Y):

 

Direction of heat transfer                       Specific heat capacity

A.                From X to Y                                          X has greater heat capacity

B.                From X to Y                                          Y has greater heat capacity

C.                From Y to X                                          X has greater heat capacity

D.                From Y to X                                          Y has greater heat capacity
