temperature effect on viscosity of honey youtube

A creamy hand soap mayīe valued more than a watery liquid soap. Products with the viscosity of the products. People tend to associate quality and value in foods and personal care Must have ingredients that make it viscous enough to cling to hair, but Lotions must be rich (viscous) to feel creamy but not gummy. Parts must do their job and be easy to apply. Oils that are used to lubricate motors and engine Or personal care products, the texture and consistency must be pleasing It must be easy to use, fulfil the need and in case of foods Viscosity of liquids is both a practical and an aesthetic factor thatĬan affect the value of a product. The cooler honey has the higher viscosity. Notice how the marble moves the fastest through the warmest honey? That's because the warmest honey has the lower viscosity. Watch this Students' Science Fair project comparing the viscosity of Honey at three different temperatures. Is true of a gas: the viscosity of a gas decreases as it cooled.Ĭooling a gas will decrease its viscosity because the particles are not To collide, increasing the resistance to flow and internal friction.Ĭooling a liquid increases the liquid's viscosity. More internal friction, increasing the viscosity of the gas.Ī liquid takes energy away. These more frequent collisions cause more resistance to flow, and consequently, The particles of gas move faster and collide with one another more often. When there is an increase in temperature, According to the particle model, particles in gasesĪre already very far apart. The opposite is true of a gas: the viscosity of a gas increasesĪs it is heated. You heat margarine in a saucepan, it melts and becomes very runny. The amount of resistance to flow and the amount of internal friction.Ī liquid's viscosity decreases when heat is added. Them to move faster and further apart from each other. Than fluids composed of small particles that are smooth and not bulky.Īdding heat to a liquid adds energy to the particles, causing Rough and bulky will have a higher viscosity (therefore a lower flow rate) Fluids composed of large particles that are In a fluid, the size and shape of particles and the temperatureĬan affect viscosity. The flow of fluids in pipes, the flow of blood and the flow of all other Viscous liquids such as oil are used to lubricate metal parts to keep Water flows easily because it has a low viscosity. More internal friction between the molecules of molasses than the molecules Viscous fluids oppose the motion of one part of the fluid relative to another.Ī viscous fluid tends to cling to the solid surface it is resting on.įor example, molasses has a greater viscosity than water. In state, or resistance to movement of the particles relative to each other. Viscosity is the resistance of a fluid (liquid or gas) to a change Watch this short introduction video from and read the following notes to clarify the information in Read pages 40-49 in your textbook, make point form notes focusingĢ. Identify, interpret and apply technologies based on the properties of fluids,ĭefine, explain and provide an example for the following terms: Viscosity,ġ. Investigate and compare fluids based on their viscosity and flow rate,Īnd describe the effects of temperature change on liquid flow.
