Hypothesis is based on observation and is possible explanation that needs to be tested.
0.0082 You have to equal out the amount of concentration with the unknown
Answer:
131 K
Explanation:
The only variables are volume and temperature, so we can use Charles' Law:
V1/T1 = V2/T2
Data:
V1 = 2.00 L; T1 = 210 K
V2 = 1.25 L; T2 = ?
Calculation:
2.00/210 = 1.25/T2
Multiply each side by the lowest common denominator (210T2)
2.00T2 = 1.25 ×210
2.00T2 = 262.5
T2 = 262.5/2.00 = 131 K
The gas was cooled to 131 K.
Topaz and quartz
Explanation:
Topaz and quartz are minerals that will scratch feldspars but will not scratch corundum. Corundum is one of the hardest substance based on moh's scale.
The hardness of a mineral is its resistance to deformation. A mineral is harder than another if it can scratch it.
The moh's scale of hardness list minerals in the order of their hardness:
- Talc
- Gypsum
- Calcite
- Fluorite
- Apatite
- Orthoclase
- Quartz
- Topaz
- Corundum
- Diamond
Diamond is the hardest and talc is the softest.
Orthoclase is a feldspar.
