A 100g sample of each of the following metals is heated from 35C to 45C. Which metal absorbs the highest amount of heat energy?

Copper- 0.385J/(g x C)

Magnesium- 1.02J/(g x C)

Mercury- 0.138J(g xC)

Silver- 0.237 J/(g x C)

Lead- 0.129 J/(g x C)

Answer #1

q = msT

   = 100*0.385*10 = 385 J Copper

q = msT

   = 100*1.02*10 = 1020 J Magnesium

q = msT

   = 100*0.138*10 = 138 J Mercury

q = msT

   = 100*0.237*10 = 237 J Silver

q = msT

   = 100*0.129*10 = 129 J Lead

Magnesium absorbs the highest amount of energy.

An insulated container is used to hold 43.6 g of water at 20.6 °C. A sample of copper weighing 11.0 g is placed in a dry test tube and heated for 30 minutes in a boiling water bath at 100.0°C. The heated test tube is carefully removed from the water bath with laboratory tongs and inclined so that the copper slides into the water in the insulated container. Given that the specific heat of solid copper is 0.385 J/(g·°C), calculate...
