Explanation:
When the water droplets are placed in oily surface, oil being non-polar, thus there will not be adhesive force between water and oil.
Thus, surface tension is the factor which is responsible for shape of the water droplets to be spherical. The water molecules are pulled into the spherical shape by the action of the cohesive forces which is acting on the surface layer. As, the medium is totally different outside, the water molecules tend to get the minimum area and thus, forming spherical droplets.
Answer : Yes, The heavier oxygen isotope in sea water is increasing as the result of growing of larger glaciers.
The global warming of the climate which is also called as global warming is helping to increase the isotopic oxygen in the ocean and sea waters. When glaciers are growing they have comparatively less isotopic oxygen but this proportion changes with the temperature.
The substance that the molecules have the strongest
attractions to one another is the sugar,
a solid. The answer is letter A. The solid has a more definite shape and
volume. The particles are locked into place. It cannot be further compressed
due to the bond that exists between the molecules. The kinetic energy of the
molecules is close to none because the molecules are so close and so compact
with each other.
Answer:
D
Explanation:
A reaction that is exothermic and causes a decrease in the entropy of the system cannot be a spontaneous reaction. This is not totally true because naturally For a spontaneous process, the entropy of the universe (system plus surroundings) must increase. This is the 2nd law of thermodynamics. The system entropy can decrease as long as the entropy of the surroundings increases enough to make the sum of the system and surroundings positive.
And we know that a spontaneous reaction is a reaction that occurs in a given set of conditions without intervention. Spontaneous reactions are accompanied by an increase in overall entropy or disorder. If the Gibbs Free Energy is negative, then the reaction is spontaneous, and if it is positive, then it is nonspontaneous.
