Volume ratio

equal volumes of both soft drinks. Consequently, if the volume increased by a doubled amount under similar experimental conditions where temperature and pressure remained constant, the density of the soda would not be expected to change due to density being an intensive property that is a ratio between the mass over the volume of a substance.2 As an intensive property, density, under similar experimental conditions, will be the same without regards to the amount presented. Doubling the volume would

size and shape on the ratio of surface area to volume. Complete the following exercises. Part 1 Let’s investigate how size influences surface are to volume ratios. Let’s assume we have a cube with a volume of 1cm3. Each side of the block equals 1cm. Picture a die for each cube. 1. How many sides does a cube have? 2. Let’s use 1 block to represent a small cubed organism and 8 blocks to construct a large cubed organism. Complete the following table. Total Volume Total surface area

area to volume ratio on the rate of diffusion is investigated. Four agars containing phenolphthalein, an indicator that turns colorless in acid, each ranging in size were used. In this experiment, the agar cubes represent cells and the time it took for cubes to turn colorless shows the rate of diffusion. Next, the cubes were placed in a beaker and just enough hydrochloric acid was added to cover them. Then, the time it took them to turn colorless was measured. It was observed that when volume increases

substance. Furthermore in the data, if the mass of the substance increased, the volume increased proportionally with it. This information ultimately supports our hypothesis. As addressed during classroom lectures, the relationship between the two variables is most likely explained by the fact that density is a ratio. It would be logical to assume that while the mass and volume increase at the same rate, the division of mass by volume would result in nearly the same number.

2018. DePaul University. Experiment one tested the effect the amount of sugar has on the fermentation rate. Four labeled 50 milliliter (mL) test tubes were used to transport each reaction to the designated fermentation tube. Each tube had a specific ratio of reactants. Test tube 1 acted as the negative control and

a) 2.2 g b) 4.4 g c) 1.1 g d) 3.6 g 15. A large wooden piece in the form of a cylinder floats on water with two-thirds of its length immersed. When a man stands on its upper surface, a further one-sixth of its length is immersed. The ratio of the masses of the man and the wooden piece is a) 1 : 2 b) 1 : 3 c) 1 : 4 d) 1 : 5 16. An ice cube is floating in water above which a layer of a lighter oil is poured. As the ice melts completely, the level of interface and upper of layer

the force exerted on an object by physical contact, was used to apply force into the pressure sensor. A pressure sensor measures the amount of force can object has and this will tell us how the pressure is affecting the number of particles. Also the volume, of the pressure

With volume and mass determined, the density formula (d = m/V) was used to determine the densities of each rock and recorded in g/ml. In the third stage of this experiment, the density of a liquid was determined and compared to known standards. A 100ml beaker

given unit volume. A physical property can be measured without changing the chemical identity of the substance. Since pure substances have unique density values, measuring the density of a substance can help identify that substance. Density is determined by dividing the mass of a substance by its volume. Density, volume, and mass have a clear relationship that can clearly be shown by the mathematical formula: Density= Mass/Volume In our experiment we used the determined mass and volume of the sample

objective of this lab was to determine the relationship (if any), between the pressure and volume of a gas given the temperature and # of molecules remained constant. Using the Boyle's law apparatus, and textbooks to demonstrate pressure it was concluded that there was a relationship between pressure and volume. However, the relationship was not a direct relationship, and it was determined that the pressure and volume of a gas are inversely proportioned. Thus,proving Boyle's theory correct. Introduction
