Jun 27, 2008· The radius of the steel ball is r = 2cm = and its specific heat is c = /kgK Analyzing the units of these given values, I thought simple unit analysis would work. For example, 1/c would give units of kgK/kJ. The volume of the ball is v = (4/3)pi(r)^3 which has units of m^3. I''m having a difficult time trying to relate these things and manipulate them to just get the mass of this ball.
