THERMODYNAMICS UNIT 1 (HEAT
TRANSFER) EXAM QUESTIONS WITH
VERIFIED ANSWERS
Geothermal - ANSWER-Of or relating to the heat in the interior of the earth.
Thermal Equilibrium - ANSWER-When two systems have the same temperature at the
same time.
Specific Heat Capacity - ANSWER-The Heat required to raise unit of mass by one
degree of temperature.
Radiant Heating - ANSWER-The method of heating the walls, floors or ceilings in order
to transfer heat to the occupants of a room.
Zeroth Law of Thermodynamics - ANSWER-The zeroth law simply says there is no heat
flow between objects that are the same temperature.
First Law of Thermodynamics - ANSWER-The first law is that heat cannot be created or
destroyed. (This is also known as the law of conservation energy.) Heat can only flow
from place to place, or change form.
Second Law of Thermodynamics - ANSWER-When heat flows from a hot spot to a cold
spot, entropy INCREASES. Every time heat flows from a cold spot to a hot spot, entropy
DECREASES.
Thermal energy - ANSWER-Internal energy of a thermodynamic system that results in
the system's temperature.
Macroscopic - ANSWER-Measurable and observed with the naked eye
Microscopic - ANSWER-Samples and objects that cannot be seen with the unaided eye.
Temperature - ANSWER-Physical property of matter that expresses hotness and
coldness, measure of the average kinetic energy of the particles in a sample.
Heat Reservoir - ANSWER-A system whose heat capacity is so large that is remains at
a constant temperature when it is in contact with another system.
Conduction - ANSWER-The flow of thermal energy directly through a material without
motion of the material itself. movement of heat by touch, solids.
