When the sweat evaporates in an endothermic exactions heat is also 'taken' from the body
If a salt has a pH less than 7, then it is an acid. All acids start with a H in there formula. The only compound that starts with an H from the listed options is HCOOK.
So the salt HCOOK has a pH<7

Answer:</h2><h2>

TRIPLE POINT:</h2>
Triple point is that temperature, at which the substance is found in all three states i.e. solid, liquid and gas. Every substance has different triple point, because Triple point is just above the freezing point and each substance has different freezing and boiling point.
<h2>
_____________________________________</h2><h2>WATER:</h2>
Water has a Melting point or Freezing Point (MP or FP) of
C or 273K and Boiling point (BP)
C or 373 K. Since the triple point is just above the MP or FP thus Triple Point of water is
C or 273.16K.

The difference in the mass of the Nitrogen-14 and Nitrogen-15 atom is because nitrogen-15 has 8 neutrons while nitrogen-14 has 7 neutrons.
<h3>What is atomic mass of an element?</h3>
Atomic mass of an element is the sum of the masses of the protons and neutrons in the nucleus of an atom.
<h3>Why is the atomic mass of Nitrogen-14 and Nitrogen-15 different?</h3>
The difference in the mass of the Nitrogen-14 and Nitrogen-15 atom is due to the difference in the number of neutrons.
Nitogen-15 has 8 neutrons while nitrogen-14 has 7 neutrons.
Therefore, the difference in the mass of the Nitrogen-14 and Nitrogen-15 atom is because nitrogen-15 has 8 neutrons while nitrogen-14 has 7 neutrons.
