Answer:
The question asks for moles, which can be obtained from P-V-T data using the ideal gas
equation: n =
RT
PV .
Now use the rearranged gas law to determine the number of moles in the sample:
!
n = PV
RT = (6.47 x 105 Pa)(5.65 x 10-4m3
)
(8.314 J
mol K )(21.7 + 273.15 K) = 0.149 mol.
All conditions except the pressure and volume are fixed, so P1V1 = P2V2 can be used: 3.62 L
101kPa
(647 kPa)(0.565 L)
2
1 1
2 = =
P
PV V
Explanation:
An intensive property is the physical characteristics that have an independent magnitude. The thermometer can be used to measure the temperature. Thus, option C is correct.
<h3>What is an intensive property?</h3>
An intensive property has been constituted of the parameters that are not dependent on the size and the mass of the sample. Density, pressure, and temperature are some intensive properties.
The first image shows a weighing balance, the second shows a volumetric cylinder, and the fourth shows a ruler used to measure mass, volume, and length respectively, which are extensive properties.
Therefore, option C. thermometer measures temperature, which is an intensive property.

Answer:
Students have investigated what's going on in the fictional town of Westfield, they learned that the mysterious reddish-brown substance in the water is actually rust, which formed because of a chemical reaction between the iron pipes and the fertilizer substance in the water.
