How do you caluate denisty?
Energy density is the amount of energy (calories) in a give unit (grams). So you just divide the calories by the grams per serving.
Why is greater density important in ammunition?
The kinetic energy of a projectile is directly proportional to its mass. When the projectile strikes, it transfers its kinetic energy to the target in the form of damage. For a fixed volume, a greater density means a higher projectile mass (density=mass/volume). Therefore a higher density means greater damage in the form of penetration and fragmentation.
How does density effect kinetic energy?
The more dense an object is the more kinetic engery it has
Does warm air rise because of density?
Yes..Low density rises. As the particle gain more kinetic energy from being heated the density decreases as the particles move further apart causing a lower density. This could then form a convenction current but that is a different topic!
Does the energy and speed of water increase as molecules get hotter?
i dont know about energy,but the speed of water increases as the density of water increases with rising temperature..
What causes a bullet to shoot?
First, a couple of terms: What most people call a 'bullet' when referring to the thing you load into the gun, is more properly called the 'cartridge'. When the gun is fired, the projectile that comes out of the barrel is the actual bullet. A typical cartridge consists of a casing, a primer, propellant, and the bullet. The propellant used to be black gunpowder, but modern cartidges use a nitrocellulose-based* 'smokeless propellant'. We still tend to call the propellant the 'powder' though. When you pull the trigger on the gun, the gun's hammer strikes the percussive primer pressed into the end of the cartridge. This causes the primer to detonate, and the primer ignites the propellant (powder) in the cartridge. The propellant burns very fast, being completely consumed in a tiny fraction of a second, and this produces hot gasses. The gasses expand, creating tremendous pressure, and this pressure forces the bullet out of the cartridge and down the gun's barrel. Kind of like when you shoot a spitwad out of a straw. *So-called single base powders are mainly nitrocellulose. There are powders called double-base powders that are mainly nitrocellulose but have 10-40% added nitroglycerine to give them more energy.
What compounds plasticize nitrocellulose?
If the application is pyrotechnical, especially rocket propellant, energetic plasticizers are preferred. Nitroglycerin is probably the most widely used and effective energetic plasticizer for nitrocellulose. Nitroglycerin plasticized nitrocellulose is, in fact, the well-known "double base" smokeless powder. The commercial "Bullseye" pistol powder is 40% nitroglycerin. There are other energetic plasticizers, having equivalent specific energy to nitroglycerin, but safer to handle and store. These include diethylene glycol dinitrate (DEGDN), butanetriol trinitrate (BTTN), and trimethylolethane trinitrate (TMETN, in mixtures with DEGDN). If the application is application/engineering plastic, a very well-established plasticizer is camphor. The mixture of camphor and nitrocellulose is the well-known plastic "celluloid". As with energetic plasticizers, there are other inert plasticizers for nitrocellulose besides camphor. Phthalate esters are prominent in this group.
What is difference in energy density and power density?
Energy density is the amount of power that can be stored ( in for example capacitance) to be then consumed over time, whereas power density is how much energy is consumed quickly like the energy stored in a capacitance can be consumed very quickly.
What is spectral energy density?
The energy spectral density describes how the energy (or variance) of a signal or a time series is distributed with frequency.You can read more in Wikipedia 'Spectral Density', but you will need good maths to understand it!
What do you call the amount of energy in a sound wave?
Sound energy density or sound density is the sound energy per unit volume (according to Wikipedia).
What is density's role in ave energy transfer in different states of matter?
Density would affect the speed in which the energy is transferred.
What kind of energy changes density in the asthenosphere?
thermal energy !
Find an expression for the energy density in terms of stress and strain?
The expression for the energy density in terms of stress and strain can be expressed as ρe.
What effect does air density have on the absorption and radiation of energy?
An increase in air density will mean a decrease in the absorption and radiation of energy. An increase of air density causes temperature and pressure to rise.
Is gun powder a compound or mixture?
Many people confuse gunpowder and black powder. Both of them are mixtures, although gunpowder, also known as smokeless powder, was 100% nitrocellulose, a compound, when it was first used in the mid 1800's. Black powder is a very intimate mixture of potassium nitrate, sulfur and charcoal. Smokeless powders today get their energy when burned from 100% nitrocellulose to mostly nitroglycerine. Most smokeless powders obtain their energy from a mixture of nitrocellulose and nitroglycerine. However, even smokeless powders made today with pure nitrocellulose are still a mixture because manufacturers add other compounds to the powder to reduce the muzzle flash, stabilize the burning rate, slow the decomposition of the powder and to neutralize any corrosive acids formed from the powder's decomposition.

Which solid element has the lowest density?
The solid element that has the lowest density is lithium. Its density is 0.534 grams per cubic centimeters. Lithium is a metal, and it does not occur freely in nature.
