Which of the properties listed below is a characteristic of a liquid but not of a gas? A. It has the ability to flow. B. It maintains its volume in an open container. C. Its molecules are constantly in motion. D. Its volume varies depending on temperature. - Answer- B A 0.100 m3 chamber is filled with oxygen gas at standard conditions (101 kPa at 273 k). Assuming ideal conditions and behavior, what will be the pressure of the gas in the chamber after it is heated to 819 k? A. 34 kPa B....

10th Grade Honors Chemistry Final Exam Flashcards Thermochemistry ️The study of heat effects in chemical reactions. Exothermic Reaction ️A reaction that releases energy in the form of heat. Examples: Combustion, freezing water. Heat generated is added to the product side (right side) because heat is released. Endothermic Reaction ️A reaction that absorbs energy in the form of heat. Examples: Melting ice, evaporating liquid water, boiling water. Heat generated is added to the ...

Which of the following is the largest component of total energy expenditure (TEE)? A. RMR B. Thermic effect of digestion C. Physical Activity D. Metabolic Stress correct answers *A. RMR* The thermogenic effect of digestion is generally thought to contribute to no more than 10% to TEE. Activity contributes to 5% - 30% to TEE. With the exceptions of burn and sepsis, metabolic stress contributes to less than 50% TEE. However, in almost all situations, RMR constitutes 60% to 75% of TEE. Wh...
