A 50 g sample of an unknown metal is heated to 90.0C. It is placed in a perfectly insulated container along with 100 g of water at an initial temperature of 20C. After a short time, the temperature of both the metal and water become equal at 25C. The specific heat of water is 4.18 J/gC in this temperature range. What is the specific heat capacity of the metal?

Question

Record your answer with two significant figures.

Answer 1

The sum of the heats gained is zero.

Heatgainedwater+heatgainedmetal=0
100*cw*(25-20)+50(cmetal)(25-90)=0
solve for cmetal.
