Gas particles want to be as free as they can, occupying as much space as they can because they are independent and the greater the temperature the greater their speed, when the temperature is low so is their speed, so they can attach to solvent molecules. When the temperature rises the gas molecules become more agitated and the glue can no longer take them inside the solvent.

it is A Acid
Explanation : Any substance that yields a hydrogen ion when placed in a water solution is called an acid. According to Arrhenius theory of Acids and Bases, Acids are those substances which on dissociation in solution generates ions. Whereas a Base is a substance that dissociates in the solution to produce ions.
(NH4)3PO4 :
N = 14 * 3 = 42
H = 1 * 12 = 12
P = 31 * 1 = 31
O = 16 * 4 = 64
-------------------------
42+12+31+64 = 149 g / mol
