Use complete sentences and show your work with units on each problem.
43. How can you distinguish between unlabeled pint cartons of milk and of cream without breaking the seals?
2
By calculating the mass and dividing it by the volume to get the density, then compare densities.
44. A student has several different-size samples of substances I and II. She measures the masses and volumes of these samples and plots the graphs shown in Figure D page 67. Which substance has greater density? How do you know?
2
2 more dense because it doesn't rise as fast as number one.
45. How can you determine the density of ice? Can you determine the volume of the ice by melting it and measuring the volume of the resulting water? Explain.
4
No, you can not determine the volume of ice by melting it down to water, this is because the volume is lowered, while the mass is kept the same, changing the density.
e
46. It is likely that the temperature readings on several thermometers will be different even when their bulbs are close together in a well-stirred beaker of water. What can you do so that data taken with the different thermometers can be accurately compared?
2
Yes, it is very likely that it will be within 2 degree in eachother.
47. Explain your reasoning.
6
a. Would adding more ice to an insulated cooler filled with canned drinks make the drink colder? (2pts)
No, it will not lower the temperature, but instead increase the amount of time that it will stay cool.
b. If not, how would adding more ice affect the drinks? (2pts)
Adding more ice would change the temperature of the drinks.
c. Describe an experiment to test your answer to part (b)? (2pts)
You could measure the temperature of the water with 3 ice cubes after 10 mins, then add 5cubes, and wat 10 minutes and measure the temperature,
48. The melting point of a few tiny
