Seven liters of a fluid with a specific heat of 2.93 kJ/(kg x K) or 0.700cal/(g x K) at 20C is mixed with three liters of the same fluid at 32C. Suppose that the fluid is insulated so that no energy can flow into it or out of it. What is the final temperature of the fluid? You do not know the density of the fluid, but you do know that the density is constant over this temperature range.

rho*7*2.93*293 + rho*3*2.93*305=rho*10*2.93*T

T=296.6K=23.6 degree celsius
