Answer the following question given this paragraph: A: Both boxes have the same volume because they are the same size. However, the books have greater mass than the feathers. Therefore, the box of books has greater density. Q: What third property is different if two boxes have the same volume but one has greater mass? Choices: - oxygen - output - diameter - density A:
density
Answer the following question given this paragraph: Fructose, a sugar found in fruit, contains only carbon, oxygen, and hydrogen. It is used in ice cream to prevent a sandy texture. Complete combustion of 32.4 mg of fructose in oxygen produced 47.6 mg of CO2 and 19.4 mg of H2O. What is the empirical formula of fructose? 11. Coniine, the primary toxin in hemlock, contains only carbon, nitrogen, and hydrogen. When ingested, it causes paralysis and eventual death. Complete combustion of 28.7 mg of coniine produced 79.4 mg of CO2 and 34.4 mg of H2O. What is the empirical formula of the coniine? 12. Copper and tin alloys (bronzes) with a high arsenic content were presumably used by Bronze Age metallurgists because bronze produced from arsenic-rich ores had superior casting and working properties. The compositions of some representative bronzes of this type are as follows:. Q: How can you prevent your ice cream from getting a sandy texture? Choices: - by using lowfat milk - by adding oil - by adding salt - by using fructose A:
by using fructose
Q: Answer the following question given this paragraph: Volcanoes at divergent plate boundaries are in the East Pacific Rise. Convergent plate boundaries, where there are trenches, have volcanoes. Hotspot volcanoes are in chains in the middle of the ocean basin. Q: What do convergent plate boundaries with trenches have? Choices: - geysers - caves - earthquakes - volcanoes A:
A: volcanoes
Question: Answer the following question given this paragraph: Kidney failure happens when the kidneys cannot remove wastes from the blood. If the kidneys are unable to filter wastes from the blood, the wastes build up in the body. Kidney failure can be caused by an accident that injures the kidneys, the loss of a lot of blood, or by some drugs and poisons. Kidney failure may lead to permanent loss of kidney function. But if the kidneys are not seriously damaged, they may recover. Q: What happens when the kidneys cannot remove wastes from the blood? Choices: - tissue failure - intestinal failure - choanocyte failure - kidney failure A:
Answer: kidney failure

Answer the following question given this paragraph: The Table below compares the specific heat of four different substances. Metals such as iron have low specific heat. It doesn't take much energy to raise their temperature. That's why a metal spoon heats up quickly when placed in a cup of hot coffee. Sand also has a relatively low specific heat. Water, on the other hand, has a very high specific heat. It takes a lot more energy to increase the temperature of water than sand. This explains why the sand on a beach gets hot while the water stays cool. Differences in the specific heat of water and land even affect climate. To learn how, watch the video at this URL: http://www. youtube. com/watch?v=dkBStF2Rnu4. Q: Why does a metal spoon heat up quickly when placed in a hot drink? Choices: - insulation - high specific heat - convection - low specific heat A:
**Answer**
low specific heat
