Question

A piece of stainless steel (specific heat =0.50 Jg^-1c^-1) is transferred from an oven at 191C^o into 125 mLof water at 23.6C^o. The water temperature rises to 50.5C^o. the mass of the steel is   M =200.3 g .)How precise is thismethod of mass determination? Explain.

Explanation / Answer

When the peice of steel is dropped into water temperaturerises and the steel temperature decreases. At thermal equilibrium q (steel) = q (water) q(water) = 125mL (1g /mL)*4.186J/g0C * (50.5 - 23.6)0C              = 14075.425J So q (steel) = 14075.425J = massof steel * 0.50J/g0C * (191 -50.5)0C           mass of steel = 14075.425J /(70.25J/g) = 200.3619g The calcualated result is more precise when there was no errorin measuring temperature. The calcualated result is more precise when there was no errorin measuring temperature.
