Using the values for the heat of fusion, specific heat of water,
and/or heat of vaporization, calculate the amount of heat energy in
each of the following:
A. joules needed to melt 90.0 g of ice at 0 ∘C and to warm the
liquid to 85.0
B. kilocalories released when 30.0 g of steam condenses at 100
∘C and the liquid cools to 0 ∘C
C. kilojoules needed to melt 26.0 g of ice at 0 ∘C, warm the
liquid...

Two identical bars, each of mass m and specific heat
c, are initially kept at temperatures
T0and 5T0respectively. The
bars are brought into contact until equilibrium is established.
Assuming the entire experiment took place in thermal insulation
from the surroundings; find the entropy change of the system.

In an experiment, 100 g of aluminum (with a specific heat of 900
J/kg·K) at 79.0°C is mixed with 80.0 g of water (with a specific
heat of 4186 J/kg·K) at 43.0°C, with the mixture thermally
isolated. (a) What is the equilibrium temperature?
What are the entropy changes of (b) the aluminum,
(c) the water, and (d) the
aluminum-water system?

Specific Heat
The heat capacity of an object indicates how much energy that
object can absorb for a given increase in that object's
temperature. In a system in which two objects of different
temperatures come into contact with one another, the warmer object
will cool and the cooler object will warm up until the system is at
a single equilibrium temperature.
Note the difference between the terms molar heat
capacity, which has units of J/(mol⋅∘C), and specific
heat, which has...
