BBC Bitesize Gcse Physics: Density Is The Mass Per Unit Volume
Introduction: Density is the ‘mass per unit volume’ ( BBC Bitesize - GCSE Physics - Density - Revision 1). In other words, it is essentially the rate/ratio of an object’s mass to its volume- measured in kilograms per metric cubed. Solids, liquids and gases all have varying densities as the density of an object increases when the atoms within it are more tightly compacted. As such, solids, having more compacted atoms in a lattice, generally, have larger densities than liquids and gases.Objects with a lower density will float and objects with a greater density will sink when placed on a liquid. Moreover, the density of an object can be obtained using the formula p=m/v- where p is the density of an object, m is its mass, and v is the volume.This

Unidentified Ufo Lab Report
1222 Words | 5 PagesThe Controlled Variable for this experiment was mass and volume. When identifying an unidentified object finding the density is the easiest way to do it because, any pure substance has a specific density at a specific temperature and each element and compound has a unique density associated

626 Words | 3 PagesBy reading the new volume of the liquid substance amount one will then subtract the initial milliliter amount from the final volume reading, thus giving you the volume of the rock sample. Using the mass of the sample rock obtained one will then divide the final volume reading unveiling the density of the
Explain Why Did The Alaskan Way Viaduct Collapse
464 Words | 2 PagesWhen atoms are cold they sink because they are more compacted and don’t move around as much. Sink or Float was a lab that showed about temperature and density changes. With the cold water we saw it sink and just stay at the bottom of the container without moving. When the hot water was added it made it rise to the top of the container and spread. That showed us that the bottom layers would be hotter and the top layers would be colder.

511 Words | 3 PagesIn addition, for calculating the mass of the pennies and the unknown substance, zero the balance and place it in the weigh boat to receive the data. Lastly, to calculate the density of the substances, use the formula D=MV, in which dividing the mass by the volume allows to do so. In order to be certain of the data that is collected, running multiple trials could help be accurate. A method to get an average value of the density can be expressed by the formula D1+D22. This formula basically allows one to add the data of all the trials and divide it by the number of trials that was performed.
Penny And Dime Lab Report
496 Words | 2 PagesIn this week’s lab we had to determine the density of a quarter, penny, and dime. My question was “How does is each coin?” Density is the amount of mass in an object. To find the density of each coin in this lab, we used a triple beam balance to find each coin’s mass and a graduated cylinder to find their volumes. With all this information, I can now form a hypothesis.
Penny In Free Fall
1022 Words | 5 PagesThese factors include the size and shape of the object. For example, the shape and size of paper of a rock differs from that of paper. But paper, because of it shape and size, would float down slower with more air resistance than the rock which has less air resistance. For example, in a well known article on the fall of an object, states, “More massive objects will only fall faster if there is an appreciable amount of air resistance present” (The Big Misconception 1). This shows the fall of an object does not care about mass but size and shape.
How Did The Cartesian Diver
217 Words | 1 PagesRene Descartes invented the Cartesian Diver, which is an object that floats but sinks when pressure is applied. Rene Descartes created a way to demonstrate the idea of buoyancy and the ideal gas law. The name of the Cartesian diver came from the inventor Rene Descartes. Some objects float in water because of the difference in density of the water. Water is much denser than air, which means when the eyedropper begins to suck in water, the density becomes greater then its overall surroundings.
Buoyancy: Why Do Some Objects Sink While Others Float?
97 Words | 1 PagesWhy do some objects sink while others float? The answer is buoyancy. Buoyancy is the ability or tendency of something to float in water or other fluid. Archimedes discovered while doing his experiments that any object that is or is sort of (submerged) in a fluid and is (acted) on by an upward or buoyant force.
Mole Mass Lab Report
372 Words | 2 PagesMolar mass is the mass (in grams) of one mole of a substance. Using the atomic mass of an element and multiplying it by the conversion factor grams per mole (g/mol), you can calculate the molar mass of that element. First, find the chemical formula for the compound. Then, calculate the relative atomic mass of each element in the compound. Next, calculate the molar mass of each element in the compound.
Gummy Bear Lab Report
538 Words | 3 Pages(The gummy bear's volume had the biggest difference between the three properties. Volume could have been the most gaining in units for several reasons. One of those reasons is after the gummy bear had soaked in the water, it absorbed some of the water. That is known as water absorption, but even though it absorbed that water when it was taken out of the cup, some of the water was released back into the cup. Some of the mass may have also dissolved because there was a slight discoloration of the gummy bear along with some of the coloration in the water.

Penny Boat Lab Conclusion
239 Words | 1 PagesOn our paper we predicted the amount of pennies that could fit in the boat before it sank. We tested the boat in the water and added pennies one by one. We then calculated the mass of pennies that fit in the boat and the density of it. The purpose of this Lab was to make a boat that holds as many pennies as possible and understand how to calculate

1363 Words | 6 PagesCHAPTER 1 INTRODUCTION The basic laws of physics involve such physical quantities as force, velocity, volume, and acceleration, all of which can be described in terms of more fundamental quantities. In mechanics, it is conventional to use the quantities of length (L), mass (M), and time (T); all other physical quantities can be constructed from these three. Standards of Length, Mass, and Time Length
