Answer:
Thermocline separate these two layers.
Explanation:
Ocean consist of three major layers on the basis of temperature.
1. Upper layer
2. Deep layer
3. Thermocline
Upper layer:
The first layer is called upper layer which is present on the surface and directly expose to the sun. The sun heat up this upper layer easily and warm it.
Deep layer
The deep layer is present below the thermocline. It is present in deep where sunlight can not approach to it and its temperature remain low.
Thermocline
It is the middle layer, present between the upper and deep layer. It separated the upper layer from deep layer. Its upper portion is warmer while lower is colder.
Answer:
C
Explanation:
O2 is a gas and gas has spread out molecules compared to the other states of matter. As such, liquid and solids have stronger intermolecular forces. Since dioxygen is the only gas in the possible answers, O2 has the weakest intermolecular force.
Answer : The volume of 1 mole of 
and 
gases are the same.
Solution: Given,
Moles of = 1 mole
Moles of = 1 mole
Moles of 
= 2 mole
Formula used for ideal gas is :
P V = n R T
According to the question, the gases are at standard temperature and pressure. So, the volume of gases only depends on the number of moles. This means that the higher the number of moles, higher will be the volume of gas.
The moles of are more than the moles of and . So, the volume of will be more.
And the moles of and are equal. Therefore, their volumes are also equal.
Therefore, the best option is the volume of 1 mole of and gases are the same.
