An aluminum ball weighing 100 g is heated and dropped into water. the amount of heat transferred to water is 6.3 kj. what could be the initial and final temperatures of the ball? (caluminum = 0.90 j/g°c)

To be able to answer the problem, it would have been easier if we were given with the initial temperature of the ball apart from the qualitative description of it being just hot. The equation that we could use to go through this problem is,
                               H = mcpdT
where H is the heat, m is mass, cp is the specific heat constant, and dT is the temperature difference. 

My answer is opptionc, just check with anyone else
