1. The problem statement, all variables and given/known data A molten metal is forced through a cylindrical die at a pressure of 168000 Kg per square meter. Given that the density of the molten metal is 2000 Kg per cubic meter and the specific heat of the metal is 0.03, find the rise in temperature during this process. Assume that the mechanical equivalent of heat is 420 Kg-meter per Kcal. 2. Relevant equations H=MCΔT and V/T =constant (probably) 3. The attempt at a solution I'm not able to understand which equations to use to solve the problem. The density is given but volume is missing, so I don't have the mass. Also, how do I find the total heat added to the molten metal in the process? Do we need more data to solve this or am I misunderstanding the question? This is not homework but a question from a competitive exam so I'm not sure what theory to be used to solve this.
