The volume of a square pyramid is (1/3)Bh where B is the area of the square base and h is the height. One student's measurements of a pyramid are B=1.33m2 h=2.79 m. Another student's measurements of the same pyramid are B=1.31m2, h=2.81 m. What is the difference in the volumes of the pyramid calculated by the two students?

A Different civilization on a distant planet has developed a new temperature scale based on ethyl alcohol. The freezing point of ethyl alcohol (117C) is designated as 0J, and its boiling point (78C) is designated as 100J. Assuming that the relationship between C and J is linear, (a) draw a graph of the line using the data above. (b) what is the slope of the line? (c) what is the y-intercept of the line? (d) Write an equation to convert J to C.
Some farmers use ammonia, NHS, as a fertilizer. This ammonia is stored in liquid form. Use the particulate perspective to show the transition from liquid ammonia to gaseous ammonia.
Specific gravity is a physical property. Beakers hold three clear, colorless liquids A, B, and C. The values of the specific gravities of the liquids are measured and then listed in the Before freezing column. The beakers are placed in a freezer until a solid crust forms across the surface of each. The beakers are placed in a freezer until a solid crust forms across the surface of each. The crusts are removed, and the liquids are warmed to room temperature. Their specific gravities are measured again, and then their values are listed in the After Freezing column. Which beakers contains a pure substance, and which contain a mixture? Explain your reasoning
Magnesium chloride is an important coagulant used in the preparation of tofu from soy milk. Its solubility in water at 20C is 54.6 g/100 g. At 80C, its solubility is 66.1 g/100 g. A mixture is made up of 16.2 g of magnesium chloride and 38.2 g of water at 20C. (a) Is the mixture homogeneous? If it is, how many more grams of magnesium chloride are required to make a saturated solution? If the mixture is not homogeneous, how many grams of magnesium chloride are undissolved? (b) How many more grams of magnesium chloride are needed to make a saturated solution at 80C?
When a marble is dropped into a beaker of water, it sinks to the bottom. Which of the following is the best explanation? a. The surface area of the marble is not large enough to be held up by the surface tension of the water. b. The mass of the marble is greater than that of the water. c. The marble weighs more than an equivalent volume of the water. d. The force from dropping the marble breaks the surface tension of the water. e. The marble has greater mass and volume than the water. Justify your choice, and for choices you did not pick, explain what is wrong about them.
What are the differentiating factors between potential and kinetic energy? a.Properties-physical or chemical b.State-solid or liquid c.Temperature-high or low d.Activity-in motion or in storage
A student checked the accuracy of two standard top-loading balances by testing them with a standard 5.000-g mass. The results were as follows: Balance 1: 4.99 g, 5.04 g, 5.03 g, 5.01 g Balance 2: 4.97 g, 4.99 g, 4.95 g, 4.96 g Calculate the average values for balances 1 and 2 and calculate the percent error for each. Which balance is more accurate?
