Energy conservation

Ferroelectricity Among the ferroelectric materials, the static dielectric constant depends on the temperature under the relation: Curie – Weiss relation: €r = P + Q/ (T-Tc), (T> Tc), P, Q are constants temperature independent. C = Curie constant Tc = Curie temperature A transition in phase is observed at temperature Tc. Above this, the material remains in Paraelectric phase (the phase where the elementary dipoles of different crystal unit cells are…

If your AC starts blowing hot air it may be due to the fact that it is freezing up. The coil is an important part of cooling your house up. The coils works by taking the warm air from your home and releasing them outside. If the coils in your AC unit become too cold they can freeze up. When your coils are frozen the ice can cause blockages, this results in you AC unit to run without cooling the home, whilst using a lot more electricity than usual. Why Do the Coils Continually Freeze Up? One…

Potential energy plays a big roll in a rollercoasters. All rollercoasters have the highest point or lowest point where the cart is at rest but either low or high. That is where potential energy is. Potential energy is the energy which results in position. Usually the most potential energy in a roller coaster is when it is about to start. The way that this type of energy is calculated and measured in P=MGH. M, being Mass, G being Gravity,…

Energy is measured in four different categories; calories, joules, kilocalories and kilojoules. Calories are the energy required to raise the temperature of 1 gram of water by one degree. A joule of energy is what it takes to move a mass of 1 gram at a velocity of one meter per second. For every one calorie there are 4.2 joules. A kilocalorie is the amount of energy to raise 1 kilogram of water by 1 degree. Kilojoules is the same a joules but it needs to be times by one thousand. The body needs…

Many people wonder what the best conditions are for growing crystals. Crystals are ordinarily made out of silicon dioxide molecules formed into an interlaced pattern ,or quartz, moreover sodium with chlorine ions interweaved (Science Line). Crystals are often found in mines everywhere, rocks, or even in your own home. These beautiful minerals are very intriguing. It is a worthwhile subject to research. My scientific question is in “In what temperature do crystals grow the longest ?”My hypothesis…

In comparison to the group work done for paper one, I do believe this was an improvement, mostly because we wrote the paper as we worked through the problem. This not only helped with preventing the procrastination of typing the paper at the last minute, but gave us time to gain an understanding of what was going in the problem by going to office hours. What I feel needs improvement is my the communication between my partner and I. partner initiative to understand the problem. There were times…

flow forth abundantly unto you. Today you are still in the process of being created and can use the laws of energy to attract into your lives the sweetest joys, an enormous peace, and all the happiness you could have, and the very desires of your soul. Our like energy is attracting other like energy. There are only two types of energy, positive energy and negative energy and these two energies either attract to each other or they repel and retract away from each other which defines how all…

EXPERIMENT # 1 INVESTIGATION OF FOURIER’S LAW FOR LINEAR CONDUCTION IN ONE DIMENSION ALONG A SINGLE BAR Theory: Fourier’s Law of Heat Conduction: It states that, “Flow of heat per unit is proportional to the temperature difference per unit length.” i.e. Q ̇/A=-k(dT/dx) By re-writing above relation, Q=dT/(dx/kA) Where, dx/kA=Conductive Resistance of the material Properties of “K”: It is a material property and a function of temperature. It may be different in different orientations. Observation…

of heat. This is when the pack gets colder. The enthalpy of dissolution for these salts determines rather they can be used in the hot or cold packs. The enthalpy of dissolution is the measurement of energy released or absorbed when a solute dissolves in a solvent. In this case the measurement of energy released or absorbed when the salt dissolves in the water.…
