A sample with a temperature of 106.51 degrees C is dropped into an insulated cup containing water whose mass is the same as the sample and whose temperature is initially 50 degrees C. The sample raised the temperature of the water to 60 degrees C. Specific heat, c = Q / m delta T
a. What is the specific heat of the sample?
b. What kind of material is it ?
