Equal volumes of three liquids of densities ρ1,ρ2 and ρ3 , specific heat capacities c1,c2 and c3 and temperatures, t1,t2 and t3 respectively are mixed together , What is the temperature of the mixture ? Assume no change in volume on mixing

Answer 1

heat= ρ1*V*c1*(T-t1) + ρ2*c2*(T-t2) + ρ3*c3*V*(T-t3)

but heat=0 as the sum of the heats iz zero (some gain, some lose).
solve for T
