Answer:
For solid salts that are soluble in the sea water, as the sea water temperature rises, the solubility of the salt in the water increases. The accompanying increase in the kinetic energy of solvent water molecules with the increase in the temperature of the seawater results in the increase in the number of solute salt inter-molecular bonds being broken by the energetic solvent molecules resulting in increasing solubility of the solids
However, for gases, the increase in temperature of the sea water results in a decrease in the solubility of all gases. The process is also explainable by the kinetic theory such that a rise in temperature of the gas seawater solution increases the kinetic energy of both the solvent water and the solute gas. The higher energy gases are moving much faster and are then then able to separate from the less mobile liquid gas combination.
The resulting effects
1) The surface (topmost) hotter portions of the sea have fewer living organisms
2) Fishes that come to the surface frequently gas for air by bringing their head above water
3) Most of the life forms are located deep within the sea
4) Formation of water movement cycles within the ocean and polar water bodies
5) Mechanical nature of the sea compared to fresh water bodies

Answer:
The amount of energy lessens
Explanation:
The producer will always have the most energy as it comes directly from the sun and the energy is passed onto each organism as they eat one another. The higher you are the least amount of energy you have! Hope that helps!
Answer:
1. 6.37 KJ
2. 3.185 KJ
Explanation:
Gravitational potential energy is a form of potential energy with respect to the force of gravity.
Gravitational potential energy = mass x acceleration due to gravity x height
i.e PE = m x g x h
1. At the top of the platform; mass = 65 kg, acceleration due to gravity = 10 m/, and height = 10 m.
Gravitational potential energy = 65 x 9.8 x 10
= 6370 Joules
The gravitational potential of the diver at the top of the platform is 6.37 KJ.
2. Halfway down; mass = 65 kg, acceleration due to gravity = 10 m/, and height = 5 m.
Gravitational potential energy = 65 x 9.8 x 5
= 3185 Joules
The gravitational potential energy of the diver halfway down is 3.185 KJ.
So you do 1.5 moles times 44(molar mass of co2) which you get 66 grams
Answer:
Final temperature =
Explanation:
Given that,
Heat added, Q = 250 J
Mass, m = 30 g
Initial temperature, T₁ = 22°C
The Specific heat of Cu= 0.387 J/g °C
We know that, heat added due to the change in temperature is given by :
Put all the values,
So, the final temperature is equal to .
