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.
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?
At absolute zero, molecules lose all kinetic energy and stop moving completely. This causes them to reach their lowest possible energy state and come to a complete stop.
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 scientific law that governs this assumption is the principle of conservation of energy, specifically the First Law of Thermodynamics. This law states that energy cannot be created or destroyed, only transferred or converted from one form to another. In this case, the heat energy lost by the metal as it cools is transferred to the water and calorimeter system, leading to a balance in energy transfer.
Which of the following would most likely be spontaneous?
A reaction that produces heat
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 1st law of thermodynamics states that the energy in an isolated system remains constant, meaning energy can neither be created nor destroyed, only transformed from one form to another.
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.
The first law of thermodynamics is related to the conservation of which quantity?
The first law of thermodynamics is related to the conservation of energy. It states that energy cannot be created or destroyed, only transferred or converted from one form to another.
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?
Perpetual motion is the concept of a hypothetical machine that operates indefinitely without any external source of energy. In reality, the laws of thermodynamics dictate that perpetual motion machines are impossible because they violate the principle of conservation of energy.
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?
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.
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?
Living things are able to defy the second law of thermodynamics by maintaining their internal order through energy intake and utilization. They use energy from their environment to organize and regulate themselves, which allows for growth, reproduction, and other life processes. This process of maintaining order in living systems is known as negentropy or negative entropy.
Why can't 200 kJ of thermal energy cannot be converted into 300 kJ of chemical energy?
Energy conservation law states that energy can neither be created nor destroyed, only transformed. The thermal energy can be converted into chemical energy, but the total amount of energy will remain the same. Therefore, 200 kJ of thermal energy cannot be converted into 300 kJ of chemical energy.
