Introduction or State of Problem How does temperature affect viscosity?
Background and Literature Search
Viscosity is the resistance of a fluid to flow. The molecules experience friction due to the molecular interaction among them. Different fluids with different viscosities flow at a different speed the more force the more viscous fluids of a fluid to flow is known to be the amount of thickness in any fluid for, example water would have low amount of viscosity and honey being thicker would have a high viscosity. Although viscosity can be known to be different depending on the density of the liquid. Force is required for any object to to travel the more viscosity that is in any liquid the more force is required
Viscosity plays a big factor in large companies manufacturing foods that are placed in our grocery stores. While the process of making the products they are controlled and measured so every

Fill the glass container with maple syrup, put container in pot with about 3 inches of water; do not turn on heat yet.
2. Drop in one penny and time (use stop watch) how long it takes to hit the bottom of the container, listen for the sound of the penny hitting the glass. Repeat 2 more times making sure you drop the penny from the same height each time; record data in a table.
3. Turn heat on to medium; start another timer or look at clock to mark Heat Time =
7.) After you have heated them to the right temperatures, pour the excess water into a dry evaporating dish. ( Be sure not to get any of the substance in your solution. )
to get an idea of how I would do my real experiment and what apparatus
Step5-Put a bar of paraffin in the big cooking pot(gum side up),put it on the burner and turn on the flame(high heat).When the bar melts put in another and when that melts another…until all are melted.(If any impurities rise to the top,skim them off with a spoon or mesh spoon.There shouldn’t be any if the gum is clean.)
the mass and initial temperature of the water. Next, impale the food sample on the needle. Next, light
in 5cm³ of water and add 4cm³ of ethanol. We had tom pour this mixture
First we turned on the electric stove and placed the water container that was about two thirds full on the stove so the water could boil.
1. Obtain a clean, dry crucible and lid, then heat them for approximately 5 minutes over a Bunsen burner
4. Pour about 300mL of tap water into the beaker. Set up a hot-water bath using a hot plate, retort stand, and thermometer clamp. Alternatively, use a Bunsen burner, retort stand, ring clamp, thermometer clamp, and wire gauze.
boiling syrup rises very high in the pan, so be sure you use one with plenty of extra capacity."(Morgan Sugarhouse, pg. 1).
Once the berry mixture has boiled, pour the sugar and pectin mixture into the pot. Using the wooden spoon, immediately start to stir the jam and continue to stir until all the sugar is dissolved. This may take a few minutes. Once the sugar is all stirred in well, place the lid back on and let the jam re-boil, stirring occasionally. This should take about 10-15 minutes. Make sure to keep an eye on it as it will boil out of the pot if you are not paying attention.
To investigate the osmotic effect of changing the concentration of sucrose solution; distilled water, 20% sucrose solution, 40% sucrose solution, 60% sucrose solution on the change in mass of potato cylinder after 30 minutes of being in solution.
Ultrasonic is the universally accepted technique to study the physico-chemical properties of the liquids, liquid mixtures, electrolytic solutions and polymeric solutions. Liquids, liquid-mixtures and solutions find wide applications in medical, pharmaceutical, chemical, lather, textile, nuclear and solvent, solution related industries. The study and understanding of the thermodynamic properties of liquid mixtures and solutions are more essential for their applications in these industries. The measurements of ultrasonic velocity in the combination of density and viscosity have been used to study the molecular interactions in liquid mixtures and solutions.
In a 100ml beaker place 50mls of water, measure the temperature of the water and record this initial temperature onto a table. Set the timer and add one teaspoon of Ammonium Nitrate to the water, stir this continuously until the Ammonium Nitrate has dissolved.
Pour one and a half cups of cold water into the pot. It depends on the rice and your preference, you may want to add 1.75 cups of water.
Fluid friction is the friction that exists when an object moves through a fluid. Fluid friction occurs when two fluid layers move relative to each other. The internal resistance to this flow is called visocity. ”Viscosity is the measure of a fluid's resistance to flow because of its internal friction”
