Joule

refrigeration was invented. Joule came pu with the idea that heat was turning into mechanical work, not producing it. He measured exchange rate between motion and heat of energy which later turned into the first law of thermodynamics.…

example, if someone what’s rubbing their hands together; the movement would produce kinetic energy. However, the vibrations would produce thermal energy. Kinetic energy occurs when an object possess movement or motion. Kinetic energy is measured in joules. Any object whether it is big or small; has kinetic energy. However, some objects have more kinetic energy than others depending on the mass of the object. The idea of kinetic energy also expresses how much work is forced upon the object. For…

Energy production Jigsaw Project individual Selena Xu 1. Second law of thermodynamics: ❖ What is the second law of thermodynamics? Well, this law talks about the quality of energy, while the quantity of energy and matter stays constant. This law tells us that heat will flow from a hotter object to a colder object, due to Newton’s second law and that when energy is transferring and transforming, some of the useful energy might be lost . ❖ Cyclic process of energy transfer is a when a series…

Bomb Calorimetry is a valuable instrumentthat measures the energy content of food and chemicals. A substance inside of the Bomb Calorimetry goes through a combustion reactions which take place inside of a closed stainless-steel container surrounded by water. In this experiment, benzoic acid and Tollhouse chocolate chips will release energy through a combustion reaction inside of the stainless-steel container. The combustion reaction that occurs will cause the water surrounding the system to…

energy of mass in motion, and the formula is E=1/2mv^2. The most important property of kinetic energy in the ability to do work, and it can be transferred from one body to another in collision, which can be elastic or inelastic. Joule found out about Energy and made joules by looking at a falling weight that was twisting a pole making temperature. Before and after, energy has to be conserved and stay the same. Examples for conserving energy would be: chemical energy to mechanical energy to heat…

Life or Death? A fourteen year old boy was undergoing surgery when his heart suddenly stopped. Otherwise known as cardiac arrest. Cardiac arrest is when the heart stops all electrical activity, eventually stopping the heart muscle from contracting. When the heart stops beating, the whole body including the brain does not receive oxygen. If the brain lacks oxygen for, ten to fifteen minutes, there could be permanent brain damage. It is crucial that the heart starts beating or someone starts…

The total change in energy is equal to the sum of the net reaction that is Hess’s Law the way I see it. It is important because it shows how energy is moved whether absorbed or released which is critical in science where logic and reason define all knowledge derived from the implications of science. Hess’s Law is used to determining difficult to measure energy changes such as the generation of hydrogen as a clean fuel in the example given in chem wiki (Shelly Cohen October 02 2013). It is also…

which someone or something is able to move or operate Velocity- the speed of something in a given direction Work- transfer of energy when a force is applied over a distance; measured in joules. Power- the rate at which energy is converted; measured in watts. Energy- the ability to cause change, measured in joules. Machine- device that makes doing work easier by increasing the force applied to an object, changing the direction of an applied force, or increasing the distance over which a force…

The purpose of this lab was to find the most efficient way to transfer heat from a chip to a water beaker. The heat transfer was coming from burning a baked lay and through our calorimeter heat energy was pushed out. Then we took it another step further by modifying our calorimeter to capture even more energy. The overall purpose was to capture as much energy as possible. “Energy is the ability to do work, or the ability to elicit change in matter.” (Castro) Energy can be defined in different…

There are many examples of symbiotic relationships in Disney’s The Lion King. A symbiotic relationship is the interaction between two species living closely together. Mutualism, commensalism, and parasitism are the three main categories of symbiotic relationships. These relationships are important in maintaining a stable ecosystem because they are similar to cause and effect. Both parties in the symbiotic relationship play a key role, and one of them missing from the equation would mean…
