What is Heat? Is it what you feel? Is it what everything looks like? Yes? Well, you are partially right. Yet, Heat is not determined by feeling but rather by “feeling” its temperature. For almost all situations, you would use a thermometer to measure thermal heat. Though, thermometers can have different types of measure. One of the most common is Celsius. Celsius is a term of measure made up of 100 equal parts, and usually called Degrees Celsius. There is also the term of measure called “Kelvin” Kelvin or absolute is divided into Kelvins. Although 0 Celsius is a greater temperature than 0 Kelvin, the change in one Kelvin is the same as the change in one degree Celsius. This is because 0 Kelvin is also called absolute zero, and that is the absolute coldest something can get.
Temperature… Is temperature what you feel? Is it how cold or warm it is outside? Well actually, to say the temperature of something is actually saying how much kinetic energy is in an object. Kinetic energy is produced by particles moving at a fast or slow speed. When a particle is moving fast, it produces more kinetic energy so that is when an item feels hot. And when an object feels cold, it’s the process vise – versa. Although you might think that the more of a hot or cold substance, the more hot or cold it will be but actually both substances are the same because the same amount of kinetic energy is involved in both.
When heat transferred, that is called conduction. Certain objects also have this conducting effect like metal for instance. For instance, if you take a spoon and place it in hot water, the hot water is transferring its thermal energy into the spoon, yet when you place your finger on the spoon, it is transferring thermal energy to your finger. That’s why the spoon should feel hot. In that case, the object is a conductor.
Some objects do not conduct to heat very well. Those objects are mostly called Insulators. Also, the transfer process in this situation is called insulation. However, an insulator does not transfer thermal energy as fast as a conductor. Because of insulation, if you wear an oven mitt, you will not feel instant heat because of the insulation of the mitt.
IS THIS INFO ALL CORRECT????
