A cube of aluminum (Cp = 0.897 J/g•K) has a temperature of 325 K. It is placed in a beaker of cold water. If the aluminum cools to 301 K as the water absorbs 815.7 J of heat, what is the mass of the cube?Use the formula q = mCT. g

A sample of an unknown substance has a mass of 89.5 g. If 345.2 J of heat are required to heat the substance from 285 K to 305 K, what is the specific heat of the substance?Use the formula q = mCT. J/g•K

What is the heat of combustion for this sample? kJ

What is the specific heat of the metal? cal/g•°C
