How much energy (J) is contained in 1.2 kg of water if its
natural deuterium is used in the fusion reaction of 21H+21H?31H+
11H? Compare to the energy obtained from the burning of 1.2 kg of
gasoline, about 6.0×107 J .
(a)
In reaching equilibrium, how much heat transfer (in J) occurs
from 1.00 kg of water at 40.5°C when it is placed in contact with
1.00 kg of 23.0°C water?
J
(b)
What is the change in entropy (in J/K) due to this heat
transfer?
J/K
(c)
How much work is made unavailable (in J), taking the lowest
temperature to be 23.0°C?
J

How much energy, in Joules, is contained in the mass of a Helium
nucleus? You may need to look up the mass of a Helium nucleus.
Include references for any numbers you quote. What fraction of mass
is released as energy when Hydrogen fuses to Helium in the sun?
How much energy is produced when the sun converts 8 kg
into helium and energy?(hint: how does this problem differ from
when the sun converts 8 kg of mass into energy)
A vessel initially contains 5.0 kg of liquid water and 2.0 kg of
ice at 0 C. Energy is added until the ice has just melted. The
temperature at the boundary where heat transfer occurs is taken to
be the system temperature during the process. The enthalpy of
melting ice is 333.5 kJ/kg. Consider the following processes used
to melt the ice.
a.) Heat is added to from the environment at 20 C. Determine the
entropy flux and the total...
A mass of 5 kg of saturated liquid vapor mixture of water is
contained in a piston cylinder device at 100 kPa, initially 2 kg of
water is in the liquid phase and the rest is in the vapor
phase.Heat is now transferred to the water and the piston which is
resting on a set of stops, starts moving when the pressure in side
reaches 200 kPa, heat transfer continues until the total volume
increases by 20%, determine a. the...
