3) A block of aluminum at a temperature of T1=30.5 ⁰C has a mass of m1=15kg. It is brought into contact with another block of aluminum that has a mass of m2=0.50m1 and temperature of T2=14 ⁰C. Heat is transferred such that the blocks come to thermal equilibrium. This aluminum has a heat capacity of c=898 J/kg⋅K. a) Input an expression for the final temperature of the blocks. b) What is the final temperature, in degrees Celcius, of the blocks? c) What was the heat, in joules, transferred to block 1?
