A.5 [kg] cube of aluminum at 10.0 [°c] is dropped into water at 30 [°c]. the specific heat of the water is 4186 [j/(kg °c)], the specific heat of aluminum is 900 [j/(kg °c)]. after a few minutes the final temperature of the water (with the aluminum cube in it) (a) assuming no heat is lost and assuming that the effects of the container can be neglected, what is the mass of the water just before the aluminum cube was dropped in? was measured as 28.98 [°c]. 1p (b) what was the volume of the aluminum cube in [m2] and in [em'] if the density of aluminum is 2830 (ko/m212 lp
