Calculate the atmospheric pressure if the boiling point of water is 81 degrees Celsius.
Answers
Answer : The atmospheric pressure of water if boiling at 81 °C will be 369 mmHg.
Explanation : The vapor pressure of boiling water can be calculated using the Antoine Equation:
log P = A - ,
where P is the pressure in mmHg,
A = 8.07131,
B = 1730.63
C = 233.426
and T = temperature in °C (81°C)
Substituting the given values, we get,
Log P = 8.07131−
Therefore, Log P =8.07131 − 5.5041 = 2.567.
Now, P = =369 mmHg.
Hence, the atmospheric pressure will be 369 mmHg.

The kind of decay which has occurred is: C. alpha decay because alpha particles have two protons and two neutrons.
What is an alpha decay?
An alpha decay refers to a type of radioactive decay in which the atomic nucleus of a radioactive element emits an alpha particle (two protons and two neutrons), thereby, producing chemical elements with a different atomic nucleus.
Basically, this isotope has a mass number that is decreased by four (4) and an atomic number (protons) that is decreased by two (2), which is an atom of Helium (He).
