Does honey retain heat longer than water? How does viscosity affect how well a liquid retains heat? What kind of water do you use to make pasta? Hot water, right! How do you get that water hot? You boil it, right again! The boiling point of a substance is the point at which liquid turns into gas. There are many ways you can change the boiling point of a substance. The chemical composition affects the boiling point of that liquid. For example, adding salt to water affects how fast the water boils. The salt lowers the boiling point of the water. Therefore, the boiling point of a liquid can be altered by adding chemicals to the liquid. Does honey boil faster or slower than water? Honey is more viscous than water. Viscosity is the measure of a fluid’s resistance to flow, it may also be thought to as a measure of fluid friction. The word “viscosity” comes from the Latin word “viscum,” for mistletoe. Viscous glue was made from mistletoe and used with lime twigs to catch birds. Most fluids have a resistance to flow, but a fluid with no resistance to sheer stress, or parallel stress, is called an ideal fluid or in-viscid fluid. Temperature is a physical property of a system that underlines the common notations of hot and cold. An example of temperature and viscosity working seamlessly together is motor engine oil. Motor oils changes viscosity depending on the temperature. If it gets to a higher temperature, the oil will be less viscous. The lower the temperature, the more viscous it will be. This means you’d want to use higher viscosity motor oil in an engine that will be running at higher temperatures. This is why you change the oil before summer and winter. The engine runs at a cooler temperature during the winter and a higher temperature during the summer. So, viscosity does affect how long a liquid will retain heat and a more viscous fluid will retain heat longer than a less viscous fluid.
