This research was conducted in the Advanced Physics Experiment Laboratory, 3rd Floor, Padang State University. An ideal gas is a collection of particles in a substance that is far enough apart compared to the size of the particles. The particles in a gas always move randomly in all directions and can collide with each other. However, in an ideal gas, the collisions that occur are perfectly elastic, which means they do not cause the particles to lose energy. In reality, there is no such thing as an ideal gas in everyday life. Real-life gases are at low pressure and the temperature is nowhere near the melting point of the gas. However, since the gas is at low pressure and the temperature is not close to the boiling point of the gas, the gas exhibits characteristics similar to an ideal gas. Therefore, in real life, gas is assumed to behave as an ideal gas.</p> febby Caca ananda Copyright (c) https://eksakta.ppj.unp.ac.id/index.php/eksakta/article/view/529 https://eksakta.ppj.unp.ac.id/index.php/eksakta/article/view/528 <p>This research aims to find out how the working principle of a simple heat engine. This research was conducted in the Advanced Physics Experiment Laboratory, 3rd Floor, Padang State University. A situation can be said to be a cycle if a number of processes that bring the system back to its original state. The heat engine will make the transfer of heat from a higher temperature to a lower one. With laboratory experimental methods and experimental results obtained that the heat engine cycle will flow heat from a high temperature reservoir to a low temperature reservoir. And when viewed from the practicum that has been done, the working principle of a simple heat engine is to take heat from the heat flowing from a high temperature reservoir to a low temperature reservoir. So that heat transfer occurs in the machine.</p> febby Caca ananda Copyright (c) https://eksakta.ppj.unp.ac.id/index.php/eksakta/article/view/528
