THERMODYNAMICS
A quantitative description of thermal phenomena requires
careful definitions of such important terms as temperature,
heat, and internal energy.
Temperature and the Zeroth Law of Thermodynamics
PROBLEMS
The concrete sections of a certain superhighway are designed to
have a length of 25.0 m. The sections are poured and cured at 10oC.
What minimum spacing should the engineer leave between the
sections to eliminate buckling if the concrete is to reach a
temperature of 50 oC?
The active element of a certain laser is made of a glass rod 30.0 cm
long and 1.50 cm in diameter. Assume the average coefficient of
linear expansion of the glass is equal to 9.0 X 10-6 (OC)-1. If the
temperature of the rod increases by 65.0 OC, what is the increase in
(a)its length,
(b) its diameter, and
(c) its volume?
A copper telephone wire has essentially no sag between poles 35.0 m
apart on a winter day when the temperature is 220.0C. How much
longer is the wire on a summer day when the temperature is 35 0C?
A combination of 0.250 kg of water at 20.0°C, 0.400 kg of
aluminum at 26.0°C, and 0.100 kg of copper at 100°C is mixed in an
insulated container and allowed to come to thermal equilibrium.
Ignore any energy transfer to or from the container. What is the final
temperature of the mixture?
What mass of water at 25.0°C must be allowed to come to thermal
equilibrium with a 1.85-kg cube of aluminum initially at 150°C to
lower the temperature of the aluminum to 65.0°C? Assume any
water turned to steam subsequently condenses.
How much energy is required to change a 40.0-g ice cube from ice
at -10.0°C to steam at 110°C?
A 3.00-g lead bullet at 30.0°C is fired at a speed of 240 m/s into a large block of
ice at 0°C, in which it becomes embedded. What quantity of ice melts?
An aluminum cup of mass 200 g contains 800 g of water in thermal equilibrium at
80.0°C. The combination of cup and water is cooled uniformly so that the
temperature decreases by 1.50°C per minute. At what rate is energy being removed
by heat? Express your answer in watts.
