What else can I help you with?
What is the study of heat called?
Py`rol´o`gyn.1.That branch of physical science which treats of the properties, phenomena, or effects of heat; also, a treatise on heat.
What are the units of the following if concentrations are expressed in mole per liter?
The units for the following equations would be: Rate of reaction: moles per liter per second Rate constant: per second Reaction order: unitless, but can be expressed as a number Equilibrium constant: unitless, as the units cancel out in the equilibrium expression
How would you express the following using symbols three formula units of magnesium bromide?
MgBr2 (s) - This symbol represents three formula units of magnesium bromide, where Mg is magnesium and Br is bromide.
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 would most likely be spontaneous?
A reaction that produces heat
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?
The total energy input is 100 units. If 20 units are used for light energy and 30 units for sound energy, then the remaining energy would be 100 - 20 - 30 = 50 units. Based on the principle of conservation of energy, this remaining energy would likely be converted mainly into heat energy.
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.
What type of science studies energy?
The field of physics, particularly the branch called thermodynamics, studies energy in all its forms. Thermodynamics focuses on how energy is transferred between systems and how it influences the properties of matter.
Would nuclear fusion break the laws of thermodynamics?
No, nuclear fusion does not violate the laws of thermodynamics. It is a process that involves combining small atomic nuclei to form a heavier nucleus, releasing energy in the process. This energy release is consistent with the principles of thermodynamics.
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 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
What are the laws of energy conversion?
Those would basically be the First and Second Laws of Thermodynamics. The First Law (energy conservation) states that the total energy can not be increased or decreased. The Second Law imposes some limitations about what conversions are possible.
Suppose 10000 units of energy are available for the grass. What is the amount of energy available for the hawk?
If the grass is at the base of the energy pyramid and 90% of the energy is lost at each trophic level, the amount of energy available for the hawk would be 10% of the 10,000 units, which equals 1,000 units of energy.
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
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.)
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.
