Convert 0C° to F°.

72% Answer Correctly

16

-32

0

32


Solution

To convert from C° to F° use:

\(F° = {9 \over 5}C° + 32\)

\(F° = {9 \over 5}(0) + 32\)

\(F° = 0 + 32 = 32\)

The asteroids in the Kuiper belt are composed of which of the following?

61% Answer Correctly

gaseous methane, ammonia, and water

minerals

rock

frozen methane, ammonia, and water


Solution

The Kuiper Belt is similar to the asteroid belt but much larger. Extending beyond the orbit of Neptune, it contains objects composed mostly of frozen methane, ammonia, and water. Most notably, the Kuiper Belt is home to Pluto, a dwarf planet that, until a 2006 reclassification, was considered the ninth planet of the solar system.


3

Which of the following states of matter exists at the lowest temperature?

71% Answer Correctly

liquid

solid

gas

none of these


Solution

Solids exist at a lower temperature than liquids which exist at a lower temperature than gases.


4

Small rocks shed by asteroids and comets that reach the earth are called:

60% Answer Correctly

meteors

meteoroids

meteorites

shooting stars


Solution

Smaller rocks shed by asteroids and comets are called meteoroids. When these rocks reach Earth's atmosphere, they burn up in the mesosphere and become meteors. If a meteor manages to reach the Earth, it is called a meteorite.


5

An element in the physical state of __________ maintains neither a constant volume nor a constant shape.

75% Answer Correctly

plasma

liquid

gas

solid


Solution

The gaseous state occurs at a higher temperature range than the solid and liquid states of the same substance. In this state, molecules flow very freely around each other and will spread out as far as they're able. Gases maintain neither a constant volume nor a constant shape.
