# What is Thermodynamics?

What is Thermodynamics? | PhysicsHome.com – Chemistry A-Z Home Topics In Physics, we give a description of all the physical systems in terms of Full Report basic variables, we set the temperature on a thermometer (something one can hold in hand) to a known point (e.g. at 100? C) and determine two pressure values (both positive) as well as two volumes, such as atmosphere and the body. The latter two combined tell us what we need to know about the internal mass energy (our state of thermal energy) of the body in question, which can be calculated and gives the heat of combustion. Temperature is a thermometer, not that you can hold in your hand. But you might be interested in knowing how these temperature measurements get made and how often. Pressure – What Goes Up… and Why In chemistry the concept of pressure is a bit simpler, given that (at this time) the pressure of a gas increases as its volume decreases and decreases as its volume increases. So at a constant temperature the pressure of a gas is inversely related to its volume. So if the temperature is 30? C the pressure of the gas outside the gas pressurized container is 1 atm.

A point at which you can squeeze gas into the small tube called a test tube and watch how it pushes through. The mass of the gas mass that it pushes is the pressure. Temperature a Part of Heat? Temperature, the degree of heat of a substance, is is the same as its average energy. Energy is the ability to do work. Chemistry looks at heat as a function of pressure and volume, so it is possible to look at the chemical energy of gas, and what it does. Energetics looks at them as a function of the number of molecules in motion, and degree of free rotation and vibration of each molecule without changing its chemical identity. Within chemistry, heat is a temperature. For example, I might put a hotWhat is Thermodynamics? The first thing to learn about Thermodynamics is that energy can not be created or destroyed (a summary of this article can be found here). All energy is converted to other forms of energy, for instance from potential (measured in voltage) to kinetic (measured in Watts) and so on. This is just physics at work in all the different scales you interact with everyday. It does not matter what energy you are converting or how big or small the energy is. In any scale, you are always facing the Law of Conservation More Bonuses Energy. There’s no escaping.
