Explanation:
number b is the answer for the question
Answer:
C. triple point
Explanation:
It is rare for a substance to have a triple point at 1 atm, so you can't measure it if you are limited to 1 atm.
It's easy to measure the melting point and boiling point, because they are the horizontal portions of the curve.
If you are adding heat at a constant rate, you can determine the heats of fusion and vaporization by measuring the times it takes for the substance to completely melt or vaporize.
Answer: You would have the worst experience ever
Explanation: Don’t try it.
Answer:
12.213 minutes will be taken for 120 g-Thalium-208 to decay to 75 grams.
Explanation:
Radioactive isotopes decay exponentially in time, the mass of the isotope (
), in grams, is described by the formula in time (
), in minutes:
(1)
Where:
- Initial mass of the isotope, in grams.
- Time constant, in minutes.
In addition, the time constant associated with the isotope decay can be described in terms of half-life (
), in minutes:
(2)
If we know that
,
and
, then the time taken by the isotope is:






12.213 minutes will be taken for 120 g-Thalium-208 to decay to 75 grams.
