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: 69. 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.
