Heat How Does the Study of Heat

Heat

How does the study of heat relate to the kinetic theory of matter?

First, the Kinetic theory of matter states that matter is made up of numerous small articles known as the atoms and molecules which are in constant motion. There are some assumptions that are made under this theory, one is that matter is made up of particles that are widely spaced and these particles are in constant motion (Ron Kurtus, 2011).

This theory also states that these molecules have great kinetic energy and move faster when subjected to higher temperatures. The moving of the particles therefore help in transferring of the heat energy by one molecule that moves fast colliding with one that moves slowly hence transferring some of the heat energy to it and in effect starts to move faster. This is how the kinetic theory of matter and the assumption that the particles are constantly in motion is related to heat as a form of energy.

The Kinetic Theory of Matter states that the material's particles have greater kinetic energy and are moving faster at higher temperatures. When a fast moving particle collides with a slower moving particle, it transfers some of its energy to the slower moving particle, increasing the speed of that particle.

What is heat?

Heat is energy produced in thermodynamics. The most significant thing to note is that heat is a kind of energy that travels in waves just like the other forms of energy and can alter the shape and state of the matter that it touches. Heat has the capacity to cause permanent chemical reactions. It is also a kind of energy that can be produced through other chemical reactions like the nuclear reaction and at times can be temporarily be trapped between insulators. Heat will always be released alongside other kind of energy as radio waves, light, sound waves etc. (Michael Fowler, 2008).

What is temperature?

The third law of thermodynamics indicates that energy cannot be transferred from one body to the other i.e. from colder condition to a hotter condition, the third law states that if all the thermal motion of kinetic energy could be removed a state known as absolute zero is likely to be created. A universe which attains an absolute zero is one with all forms of energy and matter randomly distributed across the space. An absolute zero is given by Absolute zero=0kelvin=-273.15 degrees (M.J. Fabee 2010).

Temperature can therefore be referred to as the measurement of the average kinetic energy of particles within a substance.

What is the relationship between heat and temperature?

These two are closely related and there is always a tendency to confuse the two. As noted above, the two are related in that both have to do with movement of the molecules. While temperature measures the movement of the particles within an object, heat measures the movement of the molecular as well, but additionally measures the potential energy within the object in form of degrees.

Both heat and temperature are governed by the rules of thermodynamics and work together in ensuring there is a smooth flow of energy from the hotter regions to the relatively colder areas.

How are they different?

The difference between heat and temperature is that temperature is a measurement of the vibration of the molecules, yet heat on the other hand is the amount of energy. Heat is measured in joules while on the other hand temperature is measured in degrees F, degrees C. And degrees K. One other difference is that heat energy can be carried without necessarily changing the temperature of the object. One instance of this is the ice water that remains at freezing point even as energy is added to the ice to meltdown (Jeff hazy, 2012).
