Integrated Physics and Chemistry TEKS Correlations
(6) Science concepts. The student knows the impact of energy transformations in
everyday life. The student is expected to:
(B)investigate and demonstrate the movement of heat through solids, liquids, and gases by convection, conduction, and radiation;

The uneven heating of the earth’s surface causes wind. Which of the following most likely represents how
the wind is created along the Texas coast?
B.
cool air
warm air
98.
cool air
Which of the following describes a heat transfer by conduction as a student walks across the beach on a hot
Texas day?
A.
B.
C.
D.
99.
warm air
D.
cool air
C.
warm air
cool air
warm air
A.
The student’s feet are heated by the sunlight.
The sand warms the student’s feet.
The warm air rises above the sand.
The water heats the sand.
Birds fluff up their feathers to stay warm on cold days because 
A.
B.
C.
D.
the spaces between the feathers trap air, which insulates the bird
the feather size is increased, which allows heat to be radiated
the feathers pack together, which reflects sunlight
the number of feathers increases, which increases surface area

100. How does the human body keep cool and maintain a constant internal body temperature?
A.
B.
C.
D.
The blood vessels constrict, and blood flow is reduced.
The body sweats, and the sweat is evaporated from the skin.
The body allows the heat to escape by convection.
The body increases the rate of cellular respiration.
These four items (97-100) were designed to look at conduction, convection, and radiation from
a physical science viewpoint and a biological viewpoint. These concepts are difficult to write
about or study individually because in most situations where heat is being studied, all three
forms of heat transfer are present. It is important for students to study many situations and
discuss how the heat transfer is taking place and determine if any other heat transfers are
taking place.
