Joule

Heat water in a pan or beaker until it is boiling vigorously. While the water is boiling, measure the mass of your metal object, marking off your answer to one more decimal place than what the scale marks off. Once the water is boiling, drop the metal into the water, leaving it in for about five minutes to allow it to reach the temperature of the water (100.0 °C) Place one Styrofoam cup into the other. This will be your calorimeter. Measure the mass of the calorimeter. Fill about ¾ full with…

c) is the amount of heat in joules required to raise 1 gram of substance 1 Kelvin. It is also expressed as J/kg.K. Specific heat capacity may also be expressed in the units of Calories per gram degree Celsius. Heat Transfer A simple explanation of heat capacity is the amount of energy that is transferred to a material and the change of temperature that is produced. The formula for this is expressed as: C=Q/∆T. Where C is heat capacity, Q is energy, (expressed in joules), and ∆T is the change in…

(yourdictionary.com 1). Propane’s heat of combustion is 2220 kJ/mol^-1. This means that 1 mole of propane, when combusted, would create 2220 kJ of heat (ausetute.com 1). KJ stands for kiloJoule, or 1000 Joules. A joule is the standard unit of energy. One calorie (the standard unit of heat) is equal to 4.184 Joules (kentchemistry.com 1). Converted, 50 mJ of heat are created per kilogram. MJ means “megajoule,” and says to multiply the given amount by 10^6. The fire caused by the combustion of…

accounts for 85% of the total greenhouse gas emissionsof the elcticity generating enrgies. Coal emits greenhouse gas the most out of the fossil fuels because it releases 24 kilograms of carbon per billion joules of energy as compared to oil at 18kg and natural gas at 14kg of carbon per billion joules. In addition the emission of carbon dioxide, methane is also emitted by the combustion of coal. Methane, which is also a greenhouse gas, has a potential for global warming more than carbon dioxide…

charge carriers, usually electrons or electron-deficient atoms. The common symbol for current is the uppercase letter I. Potential difference The potential difference between two points.The units for potential difference are Joules per coulomb, or volts. (1 volt = 1 Joule/coulomb). Electrical charge Electric charge is carried by the electrons ( negative charge) and protons (positive charge) within an atom. The symbol for the electrical charge is Q. Resistance The symbol…

The direction of force can be determined using the right hand palm rule. The design of the railgun is illustrated in Figure 2. After much research, the U.S navy has a goal to deploy a 64 Mega joule cannon that will utilise tungsten slugs and fire targets with speeds around 5,800 metres per second, with 10 shots fired a minute. At this rate, the railgun will accurately strike a 5-metre wide target from approximately 200 nautical miles away. Conventional…

(9.8 m / s2 at the surface of the earth) and h is the height in meters. Notice that gravitational potential energy has the same units as kinetic energy, kg m2 / s2. In fact, all energy has the same units, kg m2 / s2, and is measured using the unit Joule…

Spectroscopy is the study of objects, which is represented on the spectrum of color they radiate. An interaction of electromagnetic radiation with matter. Spectroscopy involves the process of absorption, emission, or scattering of electromagnetic radiation by either ions, atoms, or molecules. The process of absorption involves when light is absorbed by electrons that jump to higher energy levels. On the other hand, emission spectra are established when the electrons from high energy levels give…

enough energy, therefor it can be from of a collision. Kinetic energy can also be elastic or inelastic energy, however Potential Energy is an energy, but is potentially created before Kinetic Energy. Both types of energy are measured in a unit called Joules. And inside of these two types of energy there are sub types of energy's such as microwaves, gamma rays, x-rays, and ultraviolet rays. These types of energy are measured on an electromagnetic spectrum, which sub-classes the type of energy…

Introduction It is not only the immediate area surrounding the impact that would be affected by the collision. Meteorological phenomena resulting from the impact would also have a large effect on life on Earth. In particular, earthquakes resulting from the meteor would do much damage to cities and infrastructure. Our meteor is 2 kilometers in diameter, and has a mass of 9.07x1012 kilograms. Should a meteor of this size collide with Earth, the impact would cause earthquakes that have the…
