Question

1.)

A volume of 36.7 mL of H2O is initially at 28.0 oC. A chilled glass marble weighing 4.00 g with a heat capacity of 3.52 J/oC is placed in the water. If the final temperature of the system is 26.4  oC , what was the initial temperature of the marble? Water has a density of 1.00 g/mL and a specific heat of 4.18 J/goC.

Enter your answer numerically, to three significant figures and in terms of oC.

2.)

A 2.24 g lead weight, initially at 10.5 oC, is submerged in 7.90 g of water at 52.5 oC in an insulated container. clead = 0.128 J/goC; cwater = 4.18 J/goC.

What is the final temperature of both the weight and the water at thermal equilibrium?

Enter your answer numerically, in terms of oC and to three significant figures.

PLease show me how you got to the asnwer you chose as I am studying for a test!
