International Baccalaureate Diploma Program Physics HL Individual Investigation NAME: Barbara Daniels TITLE: The effect of temperature on terminal velocity a falling sphere in liquids of different viscosities Research question: how does the terminal velocity and viscosity of a liquid change as a result of the change in temperature? Personal engagement: People, who have trouble swallowing solids, must often drink thick ones to satisfy their hunger. In traditional markets, most

Viscosity Science Lab Purpose: To determine of changing the viscosity will affect the time it takes for a marble to flow through a liquid. Hypothesis: If a marble is dropped into dish soap and corn syrup, than I predict that the marble in the dish soap will travel faster than the marble in the corn syrup because I know that the viscosity of the corn syrup is thicker than then the viscosity of the dish soap. Also, the particles in the corn syrup are more compact than those in the dish soap

the viscosity and velocity of lava because a warmer type of lava would have a lower viscosity, whereas a lower temperature of lava will result in a lower velocity. Velocity is the speed and direction of a given object or substance, and viscosity is the thickness of a fluid. Fluids that have lower viscosities are thinner, and therefore able to move with greater speed. On the other hand, fluids that have a high viscosity, such as pahoehoe lava, are thicker and move slowly. Because the viscosity of a

Your Marbles to Discover a Liquid's Viscosity Which Liquid Has the Highest Viscosity? In this project we will determine the viscosities of 5 separate liquids. The liquids we will test are corn syrup, honey, vegetable oil, milk, and water. We will find their viscosities by dropping a marble into each of these liquids and measuring the time it takes for it to reach the bottom. Before we conduct the experiment, we must first understand what viscosity is. “Viscosity is the quantity that describes a

What liquids does viscosity affect the most? I’m going to find out. I’ve always been interested in cooking and how different liquids affect each other and how they react to different things. What liquids are the most viscous and what category do these liquids tend to fall into (cooking, cleaning, etc.)? Viscosity is not normally of knowledge, so what is it? Viscosity shows how much resistance that a liquid has to flow. When liquids have been acted upon by another force, more stresses appear

Binder viscosity was altered by changing temperature. The initial dispersion of the binder in the powder depends upon viscosity and shear rate applied. (Schaefer, 1996) Binder viscosity also controls the consolidation rate and hence subsequent growth via coalescence. (Ennis, et al., 1991). Results from Rough et al (2005) showed that increased temperature (lower viscosity), the regimes are reached faster because the binder is able to distribute more effectively in the mixture at a given shear rate

How does viscosity affect the speed of a sinking marble? I did this project because I wanted to know what viscosity was.Also I wanted to know how to measure it. Viscosity is the thickness of a liquid, and also what makes a liquid flow slower or faster. For example milk and honey. Honey would be thicker than milk so the honey would flow slower than the milk. Viscosity also takes place in molecular bonds. For example, if a fluid is very viscous (like honey), it would have stronger molecular bonds

Background: Viscosity is a liquid's resistance to flow. For example water would have a low viscosity while syrup has high. The higher temperature the lower viscosity and the lower temperature the higher viscosity. Cold syrup will move slower than hot syrup because the molecules are more tightly packed together while hots are very loose and free. Silica will cause the syrups viscosity to increases, so the more silica it has the more the viscosity will increase. If water is added to syrup the viscosity will

Transition From Pahoehoe to A’a In its most general sense, as the flow advances away from the vent, core temperature decreases leading to an increase in viscosity and ultimately marks a transition from pahoehoe to a’a. This point of transition is most often referred to as the “transition threshold” (Peterson & Tilling, 1980). Lava which continues to deform even after it has become highly viscous, may reach this threshold and subsequently changes to a’a. There are many factors which govern this change
