Effect Of Temperature On Viscosity

For our science project, we chose to do one that included luminol. Before we started, we found 3 cites, stating,” luminol will preform better in extreme heat than it does in room temperature or ice water.” Also one cite says,” It is used by crime scene investigators to discover spots of blood, even spots that may have been washed.” The last cite writes,” It was concluded that an inverse relationship exists between surface temperature and the reaction rate of the Luminol test.” Our question/ purpose was,” How does temperature affect luminol?” My hypothesis was that I thought that the warm water would affect the luminol more than the cold water.

The independent variable in the experiment was the mass (or amount) of the cheese and bacon balls.

In this experiment, we tested to see if the temperature of water would increase or decrease when we added different amounts effervescent tablets in the water. We had confidence that as the temperature of the water will decrease as the number of tablets increased.

Temperature is known as one of the factors that affect the solubility of a gas in its solvent. Because the enthalpy of solution for gases dissolved in waters is usually

How does the dissolve rate of the Alka-Seltzer tablets change as the temperature of the water changes? The dissolve rate is being affected by the temperature of the water. Temperature is a measure of kinetic energy in molecules (NYU). The higher the temperature, the higher the kinetic energy. Energy is required to create a reaction. Molecules with more energy come into contact with each other more often. The molecules of the reactants have to come into contact with each other, so more energy in molecules result in faster dissolving time.

However, the results are completely different. The results shown in the table, the water and cornstarch solution is most suitable liquid to use in the snow globes due to its thick viscosity compared to other solutions. Hence, the marble traveled slower as it created more drag onto the marble. Nevertheless, the water itself had low viscosity compared to other solutions because the marble reached the base faster of the measuring cylinder. As a result, it created less drag onto the marble compared to water and cornstarch solution. Therefore, the thicker the solution, the longer it takes for the marble to reach the base of the measuring cylinder. However, if the solution has low viscosity (such as water itself), the faster it the time it takes for the marble to reach the

3. The volume of a fixed mass of a liquid sample increases as the temperature rises from 20 to

When the temperature of the air is increased, it starts to rise. This happens because the hotter the air is, the less dense it becomes. The viscosity in air increases with the temperature; this is equal to the square root of the temperature. The viscosity increases because the molecules collide more frequently. Because of this, the molecules move around randomly, due to the increased number of collisions.

As the temperature of water increases, the particles of solid Potassium chloride, KCl, which are absorbing energy from its surrounding, start moving more easily between the solution and its solid state because. According to the second law of thermodynamics, the particles will shift to the more disordered, more highly dispersed solution state. I predict that as the temperature of a KCl and water mixture increases, then the solubility of the KCl will also increase.

The purpose of this assignment is to work out a parachute design and investigate parachute’s drop time. Parachutes are designed to fall slowly so that the person can land safely to the ground, as shown in figure 1. Parachutes are big, but not heavy and have a larger surface area for air resistance like traps the air from escaping out of it. This is because the air pushes the parachute back up, but the force of gravity pulls the parachute to the earth.

The data collected showed that as the Heating time increased the Falling time decreased in both the Mayple Syrup and the Honey. The Honey seemed to have a huge change in falling time as the heating time increased. There werent any outliers in the data; so therfore the results were pretty consistant. Other than the fact that the honey had a higher range in change for falling time than the Syrup; the results were very similar

In this experiment, we investigate the change in temperature caused by adding a chemical substance into the water and dissolving it. The results recorded in the table below show that our hypothesis is correct.

The scientist will be doing an experiment on how sugar and salt affects the boiling point and the freezing point of water.

Temperature affects lava flow by increasing or decreasing the viscosity, therefore affecting the speed at which the lava flows. In the graph presented, the visual data clearly shows that as the temperature of the syrup rises, the velocity increases. The overall average velocity for all the groups who used cold syrup was 1.34 cm/s. The overall average velocity for the groups who used room temperature syrup was 4.43 cm/s, and the overall average velocity for the hot syrup groups was 6.82 cm/s. This is because, like most liquids, syrup (and lava) has molecules inside that move around more freely when the liquid is in a form where the temperature is hotter. On the other hand, a colder temperature may make molecules move less, and the decrease in

Liquid has a physical property called viscosity, which tells how fast or slow it flows. The more viscous a substance is, the slower
