What happens when you place a grape in saltwater?

Adding salt to water increases its mass without affecting its volume. The water becomes denser. The water can be denser if it is added enough salt. Grapes can float in saturated salt water.

What will happen if the already swollen Raisin is kept in salt solution?

Dry raisins will swell when they are placed in water. This happens because water from the surroundings diffuses into raisins, causing swelling. These raisins will shrink if they are placed in a concentrated sodium solution.

How is osmosis End. to diffusion?

Osmosis – The movement of solvent particles across semipermeable membranes from a dilute to a concentrated solution is called osmosis. Diffusion: Particles move from an area with a higher concentration to one of a lower concentration. It is a process that equalizes the concentration in the medium.

What can make the salinity of some ocean water increase while other ocean water decreases?

Evaporation and formation of salt ice increase ocean salinity. These “salinity-raising” factors are constantly countered by processes that reduce salinity, such as continuous water input from rivers, precipitation and snow, melting of ice, and constant rain.

What are two factors that affect the salinity of ocean water?

The salinity of seawater can be affected by precipitation, evaporation and ice formation. The saltiness of seawater is affected by evaporation. Seawater evaporates and leaves behind salts. This increases their concentration.

Which two changes would increase the density of ocean water?

The temperature and salinity of ocean water determine the density. The temperature of the ocean water decreases until it freezes, and then the density of ocean water increases.

What are the two factors affecting the density of water?

Answer to: Two main factors affect water density, namely temperature and purity.

How is density affected when the depth increases?

As you go deeper in depth, pressure increases. Density is the ratio of mass to volume. Pressure causes layers below us to become very dense.

What makes something more dense?

Density can be determined by the object’s volume and mass. If two objects share the same volume but one object has more mass, it will have a higher density.

What is the main cause of surface currents?

Surface curents in the ocean are caused by global wind systems, which are powered by solar energy. Thermohaline circulation, which is a process that regulates temperature and salinity in the ocean, may also cause currents.

What would happen to Earth if ice sank instead of float?

If ice didn’t float, it would be impossible to live underwater. It stays at the top, and the ice gradually gets thicker, freezing our lakes & ponds from below. The ice on lakes and ponds freezes and forms pockets of air. This helps to insulate the water and prevents it from freezing solid.

What would happen if water froze from the bottom up?

If water froze from the bottom to the top of a river or lake, it would have devastating ecological consequences. If the water in shallow lakes freezes solid, it will cause death for all living organisms, including plants and animals.
