SCI102BX - Physical Science NameSCI102BX - Physical Science Name 1.05 Viscosity Video Lab Report(20 Points)Read lesson 1.05 - Watch the Video from lesson 1.05 or click this link to go directly to the video (Hold down the CTRL button on your keyboard when clicking the link)1. (1 point) What does viscosity mean? (Use the definition from Lesson 1.05.)2. (1 point) Is viscosity a physical property or a chemical property?3. (1 point) What is the question you are trying to answer in this lab. (Look at the Mastery Map on the first pageof Lesson 1.05 Introduction..) 4. (1 point) Tell a story about your personal experiences with viscous fluids at different temperatures. Example: molasses, maple syrup, motor oil, vegetable oil, honey.5. (2 points) State your hypothesis. (This must be an “If…,then…” statement to show the cause effect relationship between temperature and viscosity. The distance that the fluid flows indicates viscosity.)a. Viscosity is a liquid’s resistance to _flow__.b. The farther a liquid flows, the __lower___ (lower/higher) the viscosity.Viscosity is a physical property How does _tempature_ influence viscosity? If the temperature of the honey ___increases___, then the viscosity will _decreases___.6. Graph your data. Use the graph to help you answer the questions on the next page. (Use the Word Drawing tools OR use the Paint program to plot on the graph. You can also print this and complete the graph by hand, then scan it.)a) (5 points) Plot the data in this chart on the graph below.b) (2 points) Draw a trend line to characterize your data. Note: A trend line is not the same as a zigzagline that connects the points. A trend line is a line that shows the general trend of the data and, therefore, does not have to touch each point. It is a best fit line. In this case, you will have a curved trend line. Temperature(°C)(x-coordinate)Distance Covered in 30 sec(cm)(y-coordinate)70.0 7.240.0 6.120.0 5.310.0 3.70.0 1.07. (3 points) Compare your data with your hypothesis. State the actual relationship between temperature and viscosity. Cite data to support your conclusion. 8. (2 points) Extend your trend line to the edge of the graph. Use this to predict how far the honey would flow at 80°C. Explain. (Your graph must have a trend line in order to earn points for your prediction)9. (2 points) In this lab,a) the temperature of the honey is the _______________ variable. (independent or dependent)b) the distance that the honey flowed is the _______________ variable. (independent or dependent)a. As the temperature increased, the viscosity __decreased___.b. Did this match your hypothesis? (Y/N) _yes__c. Cite two data points as evidence to support this conclusion.1) Temperature of honey = ___70_____, distance flowed = ____7.2___2) Temperature of honey= ___0____, distance flowed =
