Integrated Physics and Chemistry TEKS Correlations
(9) Science concepts. The student knows how solution chemistry is a part of
everyday life. The student is expected to:

Frostbite is a danger for people and animals. It causes permanent damage to tissues exposed to temperatures
below 0°C for a prolonged time. The most likely reason that frostbite causes permanent damage to tissues is
that —
A.
B.
C.
D.
70.
(A)relate the structure of water to its function as the universal solvent;
the mitochondria produce less ATP as the water in the cell freezes
the cell membrane is less permeable as the water in the cell freezes
cytoplasm becomes more viscous as water in it freezes
cells will burst as the water in them freezes
When a person jumps into a swimming pool and lands flat on his or her stomach, the water feels like it is
solid. What property of water makes it seem to feel solid?
A.
B.
C.
D.
capillary action
high surface tension
density
high solubility
Energy Needed To Evaporate
Water
(H2O)
Methanol
(CH3OH)
2443 joules/gram 1169 joules/gram
71.
It requires more energy to evaporate 1 gram of water than to evaporate 1 gram of methanol because 
A.
B.
C.
D.
methanol molecules have more mass
hydrogen bonds form between water molecules
covalent bonds form between the methanol atoms
water molecules have fewer atoms
Many times items for IPC TEKS (9)(A) focus only on the polar nature of water. While polar
bonding in water is the intrinsic cause of the other properties of water, such as hydrogen
bonding between molecules, adhesion, cohesion, and surface tension, students should
investigate the properties of water that make it unique in the physical as well as the biological
world. Items 69-71 focus on relating the structure of water to its function. The universal solvent
part of this TEKS statement is bracketed (which means it is not tested on the TAKS) in the
Texas Education Agency’s Science TAKS Information Booklets for grade 10 and exit-level
science, because this idea of a universal solvent is now considered archaic.
