Answer:
The correct option is: salinity increases
Explanation:
Ocean is a large water body that is a division of the World Ocean. An ocean is divided into various vertical zones based upon the physical and biological conditions.
The halocline zone is characterized by a <u>rapid increase in the salinity with the increase in the depth.</u> Thus resulting in decrease in the temperature of maximum density with the increase in salinity.
In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.
Answer:
B - The energy of reactants is conserved.
D - the nuclei of atoms changes completely ( if that's the option)
It took 380,000 years for electrons to be trapped in orbits around nuclei, forming the first atoms.
These were mainly helium and hydrogen, which are still by far the most abundant elements in the universe. Present observations suggest that the first stars formed from clouds of gas around 150–200 million years after the Big Bang. Heavier atoms such as carbon, oxygen and iron, have since been continuously produced in the hearts of stars and catapulted throughout the universe in spectacular stellar explosions called supernovae.
Answer:
13.1 L
Explanation:
Using the combined gas law:
P1V1/T1 = P2V2/T2
Where;
P1 = initial pressure (atm)
P2 = final pressure (atm)
V1 = initial volume (L)
V2 = final volume (L)
T1 = initial temperature (K)
T2 = final temperature (K)
Based on the information provided in this question;
P1 = 1.95 atm
P2 = 0.65 atm
V1 = 5.0 L
V2 = ?
T1 = 20 °C = 20 + 273 = 293K
T2 = -15 °C = -15 + 273 = 258K
Using P1V1/T1 = P2V2/T2
1.95 × 5/293 = 0.65 × V2/258
9.75/293 = 0.65V2/258
0.0333 = 0.00252V2
V2 = 0.0333 ÷ 0.00252
V2 = 13.1 L
