The definition of solubility is the maximum quantity of solute that can dissolve in a certain quantity of solvent or quantity of solution at a specified temperature or pressure (in the case of gaseous solutes). For Gases, solubility decreases as temperature increases (duh...you have seen water boil, right?) The physical reason for this is that when most gases dissolve in solution, the process is exothermic. This means that heat is released as the gas dissolves. This is very similar to the reason that vapor pressure increases with temperature. Increased temperature causes an increase in kinetic energy. The higher kinetic energy causes more motion in the gas molecules which break intermolecular bonds and escape from solution. Do you need any more?
<u>Given:</u>
Force (F) acting on the box = 30 N
Acceleration produced (a) = 5 m/s2
<u>To determine:</u>
The mass (m) of the box
<u>Calculation:</u>
Formula: F = ma
m = F/a = 30/ 5 = 6 kg
<u>Ans</u>: Mass of the box is 6 kg
The answers that are correct are a, b, and d
Answer:
Japan, China, the U.S., Indonesia, Chinese Taipei and South Korea have been named by Pew Charitable Trusts on a “shame list” of countries responsible for overfishing tuna in the Pacific. According to Pew, the “Pacific 6” are responsible for 80 percent — 111,482 metric tons in 2011 — of the annual catch of bigeye tuna.
