What are two major ways that an ocean can become saltier?
Evaporation: When water evaporates from the ocean's surface, it leaves behind salts, increasing the overall salinity of the water. Formation of sea ice: When sea ice forms, the salt in the water is excluded, leading to the surrounding water becoming saltier.
What happens to the temp when a liquid evaporates?
When a liquid evaporates, it absorbs heat energy from its surroundings to overcome the intermolecular forces holding the liquid molecules together, leading to a cooling effect. As the more energetic molecules leave the liquid phase and become gas, the overall temperature of the remaining liquid may decrease.
How water evaporates from the oceans?
80 percent evaporates from the ocean. Incorrect !!! All water in the water cycle of Earth evaporates from oceans and works its way back to the ocean. Evaporation from rivers, lakes, ponds etc. is a temporary stage of the overall trip back to its origin in the oceans.
The amount of water in a cup decreases at it evaporates is this an example of an equilibrium?
No. An equilibrium is a state of balance, where nothing is changing overall.
Why do you think the water in the delta is saltier in the fall than in the spring?
The water in the delta is saltier in the fall than in the spring because there is less freshwater input from snowmelt and rainfall during the fall season. This reduced freshwater input allows saltwater from the ocean to intrude further into the delta, increasing the overall salinity of the water.
What is saltier the sea or the ocean?
The terms "sea" and "ocean" are often used interchangeably, but the ocean is generally saltier overall due to its larger size and higher evaporation rates. However, there can be variation in salinity levels between different seas and oceans based on factors like climate and proximity to freshwater sources.
How does ethanol evaporation affect the efficiency of a chemical reaction?
Ethanol evaporation can affect the efficiency of a chemical reaction by changing the concentration of reactants and products in the reaction mixture. When ethanol evaporates, the volume of the reaction mixture decreases, leading to a higher concentration of the remaining components. This can potentially alter the reaction rate and equilibrium, impacting the overall efficiency of the reaction.
How does the process of sweating help to decrease skin and overall body temperature?
When you sweat, the moisture on your skin evaporates, taking away heat and cooling your body. This helps to lower your skin and overall body temperature.
What is the change in molecular movement when water evaporates?
When water evaporates, the molecules gain enough energy to break free from the liquid phase and enter the gas phase. This results in an increase in the overall movement of water molecules as they transition from being closely packed in the liquid to being more spread out in the gas phase.
What happens to the total amount of water on earth as water evaporates from the ocean?
80 percent evaporates from the ocean. Incorrect !!! All water in the water cycle of Earth evaporates from oceans and works its way back to the ocean. Evaporation from rivers, lakes, ponds etc. is a temporary stage of the overall trip back to its origin in the oceans.
Why does perspiration cool you on a warm day?
Perspiration cools you on a warm day through a process called evaporative cooling. When sweat evaporates from your skin, it takes away heat from your body, thus helping to lower your overall body temperature.
How does evaporation make water denser?
Evaporation itself does not make water denser; instead, it involves the transition of water from a liquid to a vapor state. As water evaporates, the remaining liquid water can become denser because the lighter water molecules escape into the air, leaving behind a higher concentration of heavier molecules. This process can lead to an increase in density in the remaining water, especially in confined spaces or bodies of water where evaporation occurs rapidly. However, overall, the density of water decreases when it transitions to vapor.
