7. Why is D an incorrect answer?
a)
D says that powdered drink mix is solid, but it is actually a liquid.
b)
D says that sand is insoluble, but it actually dissolves in water.
c)
D says that lamp oil sinks, but it actually floats in water.
8.
8. Which of the following is a correct justification for selecting B as the answer?
a)
The answer is B because sand sinks in water.
b)
The answer is B because lamp oil sinks in water.
c)
The answer is B because the physical states are correctly identified and all of the substances dissolve in water.

11. Elijah is recording observations he makes of the physical properties of aluminum, copper, and iron. He tests each metal for electrical conductivity, measures their masses, and observes magnetic attraction, relative density, and solubility. During his observations, he mixes up several of his notes and needs to make corrections. Which of the following observations describes iron, but not aluminum or copper?
a)
A. Conductive grey metal, magnetic, and more dense than water
b)
B. Conductor of thermal and electrical energy, nonmagnetic, and insoluble
c)
C. Conductive yellow metal, non-magnetic, and has a mass of 112 grams
d)
D. Conductive metal, non-magnetic, and more dense than water

12. Students tested four different cups to learn which cup will keep hot water the warmest after 20 minutes. Which is the best conclusion based on the data?
a)
A. Cup W provided the most thermal insulation. After 20 minutes, the temperature of the water in Cup W only decreased 12ºC. Meanwhile, the water in Cup X decreased 15ºC. The water in Cup Y decreased 26ºC. The water in Cup Z decreased 28ºC. The water in Cups X, Y, and Z lost heat more quickly than the water in Cup W.
b)
B. Cup X provided the most thermal insulation. After 10 minutes, the temperature of the water in Cup X was 73ºC, a decrease of 7ºC. Meanwhile, the water in Cup W decreased 10ºC. The water in Cup Y decreased 18ºC. The water in Cup Z decreased 15ºC.
c)
C. Cup W provided the most thermal insulation. After 20 minutes, the temperature of the water in Cup W was 68ºC, which was higher than the water in the other cups after 20 minutes. The water in Cups X, Y, and Z took in more cold energy from the surrounding air than the water in Cup W.
d)
D. Cup Z provided the most thermal insulation. The temperature of the water Cup Z decreased quickly to 65ºC after 10 minutes. After 20 minutes, the water in Cup Z reached 52ºC. The water in Cup Z decreased 28ºC over 20 minutes.
