When I saw this on a website recently I just had to investigate further:
Blow up your last Rolo.
Observe how the chewy toffee centre fails to act in a chewy manner when exposed to internally concentrated explosive forces.
Be Afraid Funtley…. Be Very Afraid….

In this project I shall be trying to determine the Boyle temperature for a set gas based around the Redlich and Kwong gas equation that has been written in a form analogous to the van der Waals equation.

The equation is:                
Which can be re-arranged to:        
First We Find The First Derivative Of This Equation:

From a standard [...]

From a very early age, in fact ever since my dad started to teach me maths at the age of three or four, I have been interested in solving problems. This was partially due to my inquisitive nature, and my mum’s interest in crosswords, and other such puzzles that I tried to help her solve [...]

There have been many technological advances in the fields of chemistry physics in the past, but the most significant of those have been in physics in the last two hundred years or so. As a result of this observation, when considering evaluations of past achievements, I shall be limiting my discussion to approximately the last [...]

Simon Singh’s parents emigrated from the Punjab in India to Britain in 1950. He grew up in Somerset, and then went to Imperial College, London, to study physics, before completing a PhD in particle physics at Cambridge and CERN.
In 1990, he joined the Science Department of the BBC as a producer and director on programmes [...]

Aim:

The aim of this experiment was to observe the different factors that influence the effective pumping speed of a rotary pump.
Background:

The very first pumps were used for raising water and mining, as they still are today, but nowadays pumps have many more applications, other than just moving fluids around (although that’s still essentially all they [...]

The modern picture of the electronic configuration of atoms takes the form of the ‘atomic shell model’ whereby the configurations of all atoms are considered as modified versions of the configuration of the hydrogen atom, the simplest atom in the periodic table. The atomic shell model states that the electrons orbit the nucleus of the [...]

When a charged particle is accelerated in a uniform magnetic field it will move along a circular path in a plane perpendicular to the direction of the magnetic field. This is due to the fact that the magnetic force acting on a charged particle in a uniform magnetic field is always perpendicular to the velocity [...]

    

My project is going to concern the chemistry of the gas phase 2H2 + O2
à 2H2O reaction.
This reaction is usually thought of as being solely explosive (it’s used in rocket fuel, for example), but this isn’t necessarily always the case. The reaction itself has many individual ’sub-reactions’, is very complex and as a result it’s [...]

The System In Equilibrium:

When the system is in equilibrium the total force F on the system is 0 as there is no driving force F(t).
There is no y diplacement, and therefore no velocity term and hence no drag term either.
The force of gravity and the restoring force of the spring are the only forces able [...]
