Why does salt dissolve faster in hot water rather than cold?
In hot water the water molecules are moving at a faster rate than they move in cold water. The faster moving molecules hit the salt molecules with greater force and knock them away from the other salt molecules faster. That way the salt molecules dissolve in the water quicker.
What is greater than and lesser than?
Greater than > Lesser than <
Is there very little space between the molecules of a liquid?
In liquids, molecules are close together but with some space between them. The molecules are constantly moving, allowing them to flow and take the shape of the container. The distance between molecules is greater than in a solid, but less than in a gas.
What makes hot air turn to cold air?
Heat is defined by how fast molecules are moving. Fast moving molecules will have a higher temperature than slow moving molecules. The kinetic energy of the hot air is transferred to the cold air, which means the cold air becomes a little warmer, and the hot air becomes cooler.
Why are solid dense than liquid and gases?
The atoms or molecules are moving faster, causing them to be farther apart.
What Change is happening as a liquid changes to a gas?
its boiling, the molecular structure of the liquid is changing. The molecules are moving farther apart and moving faster. Gas molecules are fartherest apart and move randomly and rapidly. If you put more air into a balloon it becomes harder because the air molecules are moving faster in a defined space. It explodes when the molecules exert more pressure than the balloon itself can stand.
Which has more kinetic energy the molecules in a gram of ice or a gram of steam?
The molecules in a gram of steam have more kinetic energy than the molecules in a gram of ice. This is because steam has a higher temperature and its molecules are moving faster compared to the slower-moving molecules in ice.
Why does cool water move slow?
Cool water moves slow because the molecules are moving slow. In hot water, molecules are moving fast, thus, hot water seems to move faster than cold water at times.
What is lesser pilgrimage?
a lesser pilgrimage is a pilgrimage that is lesser than the normal pilgrimage
How dies the friction between the ground and molecules in the air affect wind?
The wind at the surface of the ground where the molecules are having friction is moving slower than the wind above the surface.
Why does hot water dissolve more salt than cold water?
Salt dissolves quicker in hot water because the water molecules are moving faster than the cold water molecules, thus they have more contact with the salt molecules NaCl and break them up much faster.
The friction between moving molecules in a liquid is called?
The friction between moving molecules in a liquid is called viscosity. Viscosity is a measure of a fluid's resistance to flow, with higher viscosity fluids being more resistant to flow than lower viscosity fluids.
