Suppose you place a hot pack into a vacuum chamber and the hot pack caused the temperature to rise from 21 degrees to 23 degrees

Celsius. If the
pressure was initially 1 atmosphere, what equation would you use to determine the new pressure at the new temperature? Assume volume, and quantity of
gas are held constant.
Select one:
a. P1/T1 = P2/T2
b. P1V1 = P2V2
c. P1T1 = P2T2
d. P1n1 = P2N2

k0ka [10]

Answer:

The scientist is observing an intensive property of a superconductor.

Explanation:

An intensive property is a bulk property of matter. This means that an intensive property does not depend on the amount of substance present in the material under study. Typical examples of intensive properties include; conductivity, resistivity, density, hardness, etc.

An extensive property is a property that depends on the amount of substance present in a sample. Extensive properties depend on the quantity of matter present in the sample under study. Examples of extensive properties include, mass and volume.

Resistance of a superconducting material has nothing to do with the amount of the material present hence it is an intensive property of the superconductor.
