Ask the students to discuss how it might be possible that Diet Coke, which contains a sweetening compound of larger molecular mass, is somehow less dense than regular Coke. Why is the sky blue? There are 1 2 3 4 5 6 7 8 9 10 11 12 pages in this feature. For the liter tank, this would be approximately g of salt. Now have the students revise their mass ratio calculation. What are the states of matter? The can of Diet Coke shown above has a mass of about g, as does a second spare can.
Many science teachers perform a demonstration in which they immerse sealed cans of Coke and Diet Coke in a tank of water. The can of Coke immediately sinks, while the can of Diet Coke floats. Some instructors have adapted this demonstration as an experiment to teach students the principles of density and buoyancy. The experiments allow students to conduct measurements so that they can devise a scientific explanation for the observed behavior. Density represents the relationship between a substance’s mass and the amount of space it occupies, i. Pure water exhibits a density of 1. Most other liquids exhibit densities between 0. Coca Cola consists mostly of water.
Seems magnificent what is the mass of diet coke phrase happens can
What would happen if you turned on your headlights while moving at the speed of light? Some instructors have adapted this demonstration as an experiment to teach students the principles of density and buoyancy. Why do your feet stink? Subject Area. Archimedes’ principle states that the buoyant force exerted by water or any other fluid on an object is equal to the weight of the water displaced by the object. In other words, the mass of the can must be somewhat less than 1. The can of Diet Coke, however, contains only 0. Mathematical Explanation. Otherwise, it sinks.
|What is the mass of diet coke day||Demonstrate, using the two water baths, that a can of Coke will sink in water, while a can of the exact same size containing Diet Coke will float. Ask the class how this might be explained. The students should know that this indicates that the can Diet Coke is less dense than water, while the can of regular Coke is more dense. Under such a scenario, the Diet Coke can should be more dense than the Coke can, which is contrary to observation.|
|Pity what is the mass of diet coke commit error suggest||Why is the sky blue? What is lightning? What are the states of matter? Does hot water freeze faster than cold?|
