Q: Q: The ability of matter to burn is called? Read this paragraph and choose the correct option from the provided answers: Flammability is the ability of matter to burn. Wood is flammable; iron is not. When wood burns, it changes to ashes, carbon dioxide, water vapor, and other gases. After burning, it is no longer wood. Choices: - solubility - eccentricity - unpredictability - flammability A:
A: flammability

Q: Q: Which type of pressure forces fluid out of the capillary? Read this paragraph and choose the correct option from the provided answers: Osmotic Pressure The net pressure that drives reabsorptionthe movement of fluid from the interstitial fluid back into the capillariesis called osmotic pressure (sometimes referred to as oncotic pressure). Whereas hydrostatic pressure forces fluid out of the capillary, osmotic pressure draws fluid back in. Osmotic pressure is determined by osmotic concentration gradients, that is, the difference in the solute-to-water concentrations in the blood and tissue fluid. A region higher in solute concentration (and lower in water concentration) draws water across a semipermeable membrane from a region higher in water concentration (and lower in solute concentration). As we discuss osmotic pressure in blood and tissue fluid, it is important to recognize that the formed elements of blood do not contribute to osmotic concentration gradients. Rather, it is the plasma proteins that play the key role. Solutes also move across the capillary wall according to their concentration gradient, but overall, the concentrations should be similar and not have a significant impact on osmosis. Because of their large size and chemical structure, plasma proteins are not truly solutes, that is, they do not dissolve but are dispersed or suspended in their fluid medium, forming a colloid rather than a solution. Choices: - air - gas - combustion - hydrostatic A:
A: hydrostatic

Q: Q: What is greatest source of hazardous waste? Read this paragraph and choose the correct option from the provided answers: The greatest source of hazardous waste is industry. Agriculture is another major source. Even households produce a lot of hazardous waste. Choices: - study - water - heat - industry A:
A: industry

Q: Q: Phosphorus exists as several allotropes, the most common being red, black, and what? Read this paragraph and choose the correct option from the provided answers: Phosphorus exists as several allotropes, the most common being red, black, and white phosphorus. White phosphorus consists of tetrahedral P4 molecules and melts at 44.15C; it is converted to red phosphorus by heating at 400C for several hours. The chemical differences between red and white phosphorus are considerable: white phosphorus burns in air, whereas red phosphorus is stable; white phosphorus is soluble in organic compounds, whereas red phosphorus is not; white phosphorus melts at 44.15C, whereas red phosphorus melts at 597C. If the enthalpy of fusion of white phosphorus is 0.659 kJ/mol, what is its S? Black phosphorus is even less reactive than red. Based on this information, which allotrope would you predict to have the highest entropy? the lowest? Why?. Choices: - purple phosphorus - yellow phosphorous - green phosphorus - white phosphorus A:
A: white phosphorus
