A liquid moves faster when it is heated because the particles in the liquid are hitting each other, and subsequently repelling each other at a higher rate and force than before they were heated.
Basically, the cohesion (attraction between the molecules/particles) and the adhesion (attraction of the molecules/particles to others around them, ie. wetness) are decreased, making the liquid more fluid.
Try to imagine a cart full of tennis balls. As you pour them out (with the cart tipped over to an angle of, say, 65 degrees) they fall out at a specific rate.
However, if you caused the cart to vibrate vigorously as you allowed them to pour out (with the same angle, and the same number of balls) they would pour out much faster.
Just try to remember that the cart only represents the molecules of the container you're pouring the liquid from (like a cup or a beaker).

∙ 12y agoThe measurement of resistance between two consecutive layers of liquid is called VISCOSITY. It has inverse relation with temperature. When temperature rises, it become lesser, so the Resistance between two layers become less. As the result hotter liquid flows faster then colder liquid.
Wiki User
∙ 11y agobecause the heat makes it thinner and more easier to flow.
Wiki User
∙ 10y agoBecause a hot liquid has a lower viscosity.

Wiki User
∙ 7y agoYes they do. The effect of heat depends on the specific heat of the liquid. The higher the specific heat, the grater the amount of heat required to achieve the same temperature change.

Why is the rate of diffusion of gases more rapid than that of liquids?
Gases diffuse faster than liquids because the intermolecular forces holding gases together are significantly weaker than those holding liquids together. This allows the molecules of the gas to move faster than those of a liquid.
Why do substances diffuse faster in hot than in cold temperatures?
In hot water molecule were moving around faster so substances diffuse faster than in cold water.
Is starch more soluble in hot or cold water?
Hot water, because particles will move faster and spread apart more than in cold water, thus making it more soluble.
Why do antacids dissolve faster in warm water?
It has more energy in the form of water molecules that vibrate and move around faster than those in cold water.
Why sugar desolve in hot water more than cold water?
Sugar dissolves faster in hot water than cold water. It doesn't dissolve more or less. Temperature only effects the rate of reaction.
Why diffusion occurs more quickly in a gas than in a liquid?
Diffusion in gases is faster than in liquids because the particles in gas move way faster than in liquids. The gas particles therefore spread out more quickly and diffusion is completed faster.
do solids freeze faster than liquids?
yes solids freeze faster than liquids
Do liquids heat up faster than solids?
Yes, liquids heat up faster than solids.
Why is the rate of diffusion of gases more rapid than that of liquids?
Gases diffuse faster than liquids because the intermolecular forces holding gases together are significantly weaker than those holding liquids together. This allows the molecules of the gas to move faster than those of a liquid.
Why do molecules of gas travel faster than liquids?
gas molecules are less densily packed and hence move faster than liquids
Which medium does sound travel fastest in?
Sound travels faster in solids than it does in liquids. thus, sound travels faster in liquids than it does in solids
Why can liquids change its shape?
because the atoms in the liquid moves faster than a solid and has more freedom.
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.
Why do apple juice freeze faster than water?
Apple juice is denser than water and has more solids in it than water. Solids are easier to cool than liquids and thicker liquids are easier to cool than thinner liquids. Therefore, apple juice freezes faster
Do liquids expand faster when heated than solid?
no
Are liquid particles spread apart?
yes. solids are more dense than liquids and the particles in gases are more spread out and faster.
What in solids move faster than in liquids?
Sound will usually move faster in a solid than in a liquid.
