You are wrong. What is conserved is energy = work done There is a work mechanical equivalent to heat. 1 calorie = 4.1868 Joules The heat /mechanical equivalence is a pillar stone of thermodynamics, so that your are wrong because you miss that equivalence : 1 calorie = 4.1868 Joules The next step requires to know that different substances at a given temperature have different amounts of energy (calories). A metal at 300K temperature carries more energy that water at 300K. So metals can do more work then water, when both are placed in contact with the air atmosphere at a lower temperature, for instance.
