How would you express the following using symbols three formula units of magnesium bromide?
3MgBr2
Converting kilograms to Joules?
Kilograms are mass units, Joules are energy units. You could use Einstein's energy-mass equivalence and multiply the mass (in kg) by the speed of light (in m/s) squared; that would give you the energy equivalent in Joules of a given mass.
What is the scientific law that is the basis for the assumption that the heat energy lost by the a metal as is cools is equal to the heat energy gained by the water and the calorimeter?
The energy transfer within the system (between the water and the lead sinker) must obey the first law of thermodynamics. Meaning, "...that energy can not be created or destroyed, it can only be changed from one form to another or transferred from one body to another, but the total amount of energy remains constant (the same)." So due to the conservation of energy, the heat lost by the lead sinker is transferred to the water in equal amounts. We must assume here that the experiment is well controlled and there are negligible sources of heat transfer from unintended external sources.
What happens to molecules when the temperature reaches absolute zero?
by the laws of thermodynamics, nothing can ever reach absolute zero. Theoretically, molecular motion would stop. They would still be molecules, they would just not move.
Which of the following energy conversion occurs inside in a battery electrical to chemical thermal to electrical or thermal to chemical?
None of them Chemical energy stored in the battery is converted into Electrical (with some heat / thermal 'wasted'). However if you recharge a battery you would get electrical to Chemical.
Which would mean that the energy in an isolated system would remain constant law of conservation of matter 1st law of thermodynamics second law of thermodynamics or the atomic theory of matter?
The first law of thermodynamics states that the energy of an isolated system is constant.
If you where to measure a length of a fence which of the following S1 units would you use?
There are no "following" units, but I would use metres.
If 100 units of electricity produce 20 units of light energy and 30 units of sound energy how many units of heat energy would the remainder of the energy produce?
50 units
The first law of thermodynamics is related to the conservation of which quantity?
Yes. There are no known exceptions - otherwise it would not be considered a law
What type of science studies energy?
The study of energy would be a specialty within the field of physics, which encompasses matter, energy, space, and time.
What is perpatual motion?
It is the idea of a machine continuously producing energy, without energy input - or producing more energy than what is put into the machine. This would violate the First Law of Thermodynamics (conservation of energy), and in general, it is not believed to be possible. No process is known which violates the conservation of energy. (A "perpetual motion machine of the second kind" would violate the Second Law of Thermodynamics; this is generally believed to be impossible, too.)
What law of thermodynamics states that some useful energy is lost in a reaction?
because partly will be emissed to the environment, which cant be reused. For more information refer to sustainability studies, which are looking, among other things, how heat directed to the environment can be minimised
Would nuclear fusion break the laws of thermodynamics?
I can't answer that but I have asked myself this question; how can you get out more energy than you put in?
What universal law states that energy can neither be created nor destroyed and can always be accounted for as work stored potential energy or heat?
That would be the First Law of Thermodynamics
Which law of thermodynamics applies to percent of harvested energy?
The 2nd law of thermodynamics can yield predictions on the maximum efficiency of a process that seeks to extract useful energy. An example would be the Carnot cycle which gives the maximum percent of energy that can be harvested and turned into useful work as heat moves from a heat source to a heat sink.
How does one explain the nature of living things if the secound law of thermodynamics is correct?
An oversimplification of the second law of thermodynamics would state, "Everything cools down." Then the nature of living things would be the need to add energy to counter this cooling down. Humans add this energy by eating food and combining it with oxygen. Thus, the food and oxygen produces energy that can be lost to entropy.
Why can't 200 kJ of thermal energy cannot be converted into 300 kJ of chemical energy?
Quite simply, that would violate the law of conservation of energy - a.k.a. the First Law of Thermodynamics. No exception has been found so far for this law. This would be like trying to get something out of nothing; the total amount of energy has been found to be constant - no exceptions.Quite simply, that would violate the law of conservation of energy - a.k.a. the First Law of Thermodynamics.
