By heating the gas up you make the molecules move faster, which would normally increase the pressure. Imagine that you have a gas inside a movable piston and you heat that gas up. Pressure is related to the amount of force that the molecules apply to the walls of the container. ' Iso' means the same, and ' baric' means pressure. Isobaric ProcessĪn isobaric process is one where the pressure of the system (often a gas) stays constant. Those terms are pretty hard to understand just from the names, so let's break them down one at a time.
The four types of thermodynamic process are isobaric, isochoric, isothermal and adiabatic. The Four Types of Thermodynamic Processes In this lesson, we're going to look at the four types of thermodynamic processes. A thermodynamic process is any process that involves heat energy moving within a system or between systems. Then we can look at how heat moves in, out and within that system. We choose the system we want to look at for convenience. Our system could be the inside of a thermos flask, or it could be the whole human body or just our skin, or the gas inside a piston.
A system is just a particular object or area we're looking at. These are examples of the many things we can do with heat if we understand how it moves within or between systems. It's also how we've been able to build refrigerators and large insulated coolers to take to the beach. Extreme heat or cold can damage our tissues, so it's a pretty important thing to understand. Heat transfers from hot places to cold places - or in other words, heat spreads out. The heat from the hot pan moves into your hand rapidly, and when touching an ice cube, you lose your own body heat fast. Both of those things happen because of how fast heat is moving.
If you touch a hot pan out of the oven you'll burn yourself. If you touch a block of ice, it isn't always pleasant unless it's a really hot day. Thermodynamics is the study of the movement of heat. Those random motions are what we call heat energy. Every atom and molecule in your body undergoes constant random motions that are impossible to predict.
