How does lava temperature impact viscosity and velocity? The higher the temperature the lower the viscosity which allows it to develop a smooth surface skin‚ but this is quickly broken up by flow of molten lava‚ it creates a rough‚ clinkery surface. The lower the temperature of the magma the higher the viscosity which allows the lava to travel down the slope. In the group the average velocity was 0.91 cm/s . How the “lava” flowed was in a high viscosity and a low velocity because the “lava” was

Lab 2 Report for MATSE 473 Determining Molecular Weight using Solution Viscosity Name: Mengfang Li Group D Lab Partners: Michael Lorenzo‚ Peter Mcclure 01/24/2012 Introduction: This lab was designed to demonstrate the method to measure the intrinsic viscosity of the prepared polystyrene. Intrinsic viscosity‚ which is measured from the flow time of a solution through a simple glass capillary‚ has considerable historical importance for establishing the very existence of polymer molecules

relatively high viscosity index (Ştefănescu et al.‚ 2005; Wikipedia‚ 2016b). Viscosity is defined as a measure of a resistance against its flow‚ which can be measured by numerous of methods while the viscosity index is a measure of changes in viscosity with temperature. Few articles have noted out the importance of viscosity index in a lubricant. Fitch (2012) mentioned it is too often the viscosity index is disregarded as a lubricant selection parameter as it is very important. The viscosity index of lubricants

experiment aimed to study the effect of various denaturants on albumin and casein protein extracts through viscosity measurements. 5 mL samples of native and denatured protein solutions were prepared‚ using -mercaptoethanol‚ urea and SDS as denaturants for albumin‚ and NaOH‚ NaCL‚ HCL‚ -mercaptoethanol‚ urea and SDS for casein. 5 mL blank solutions for each denaturant used were also prepared. The viscosity of the solutions were determined using Ostwald viscometer. ____________________________________________________________________________________

denaturants act upon or denature protein differently. This was determined using the principle of viscometry. An Ostwald viscometer was used to measure the viscosity of the prepared native‚ blank‚ denatured native and blank with denaturant solutions. The time required for the said solutions to pass through the viscometer were recorded and their viscosities were then calculated using the data. Experimentally‚ urea was found to be the best out of the six denaturants that were used. Results and Discussion

Light Transmission Through Liquids With Different Viscosities Introduction Aim This experiment investigates the effects of different liquid viscosities on light transmission. The results of this experiment could greatly benefit marine biologists or other marine scientists. This would help them figure out how their flashlights would work in different water conditions in the ocean. Background Research Spectrophotometers are devices that measure the amount of light absorbed by a certain liquid

INTRODUCTION In this lab‚ we will be measuring the viscosity of samples of polyvinyl alcohols in order to determine the molecular mass of their components. Polyvinyl alcohol is an example of a synthetic polymer‚ which is a macromolecule. The general chemical structure of such compounds are well-characterized‚ although variation in characteristics such as molar mass‚ chain length‚ and extent of branching are not obvious from merely looking at their molecular formula. There is also the complication
Premium Polymer Chemistry Liquid
A liquid with a high viscosity will not be able to flow well. For example‚ syrup or molasses both flow very slowly so they would have a high viscosity. Liquids such as water or alcohol would have a low viscosity because they flow very easily. Intermolecular forces that affect the molecules shape and composition will directly affect the viscosity of the molecule. An example of this can be observed between ethyl alcohol and ethyl glycol
