Question

Water has a specific heat that is 10 times greater than that of
copper. A 5.0-kg block of copper that is initially at 50
^{o}C is placed in 1.0 kg of water that is initially at 20
^{o}C. The copper and water are in a thermally isolated
container. When the copper and water come to thermal equilibrium,
what is the temperature?

Answer #1

In this question, assume that the specific heat of water is 4
×10^3 J/(kg degrees C) and the latent heat of vaporization pf water
is 2X10^6 J/Kg. If we mix 1.0 kg of water at 0 oC with
0.01 kg of steam at 100 oC, when the mixture comes to
thermal equilibrium.
A: a mixture of steam and water at 100 degrees C
B: All water at a temperature greater than 50 degrees C
C: All water at a temperature...

Part A
A copper pot of mass 2.5 kg contains 5.2 litres of water (i.e.
5.2 kg) at room temperature (200C). An iron block of
mass 9.4 kg is dropped into the water and when the system comes
into thermal equilibrium, a temperature of 380C is
measured. What is the initial temperature of the iron block? Give
your answer in oC to three significant figures.
Part B
Iron has a specific heat that is larger than that of copper. A...

The specific heat of a 90 g block of material is to be
determined. The block is placed in a 25 g copper calorimeter that
also holds 60 g of water. The system is initially at 20°C. Then 129
mL of water at 80°C are added to the calorimeter vessel. When
thermal equilibrium is attained, the temperature of the water is
54°C. Determine the specific heat of the block.

The specific heat of a 103 g block of material is to be
determined. The block is placed in a 25 g copper calorimeter that
