Q & A

What is the main objective of the practical session conducted by Yulia Dwi Wahyuni?

The main objectives of the practical session are to explain thermodynamic processes such as isothermal, isobaric, and isochoric processes, formulate the relationship between pressure, temperature, and volume of gas in a closed space, and analyze related graphs.

What tools are used in the practical session?

The tools used include a laptop or smartphone, a simulation application (Part3), and various instruments like a thermometer, barometer, a pump to control particle movement, and a ruler for measuring volume changes.

What does the isothermal process involve, and how is it conducted in the experiment?

The isothermal process involves maintaining a constant temperature while varying the volume of gas. In the experiment, Yulia sets the temperature to 300 Kelvin and adjusts the volume by changing the length of a container. The experiment measures the pressure at different volume values.

How does the isobaric process differ from the isothermal process in the experiment?

The isobaric process involves maintaining a constant pressure while varying the temperature and volume of the gas. Yulia adjusts the pressure and observes changes in temperature, noting that the volume remains constant during the process.

What is the importance of maintaining constant volume or pressure during the experiments?

Maintaining constant volume or pressure allows for the study of specific thermodynamic principles, such as how temperature affects pressure at constant volume (isochoric) or how volume changes with temperature at constant pressure (isobaric). This helps demonstrate fundamental gas laws.

What is the relationship between pressure, temperature, and volume in these experiments?

The relationship is based on the ideal gas law, where temperature, pressure, and volume are interrelated. In the isothermal process, the product of pressure and volume remains constant at a given temperature. In the isobaric and isochoric processes, the changes in pressure and temperature or volume are closely related according to the laws governing gas behavior.

What is the purpose of the simulation application in the experiment?

The simulation application is used to visualize and manipulate the thermodynamic processes, allowing Yulia to perform controlled experiments on gas behavior in a closed system without needing physical equipment.

What challenges are faced during the isobaric process experiment?

A challenge during the isobaric process is ensuring that the volume remains constant while the pressure is adjusted. The minimum length of the container also limits the range of volume changes that can be measured.

How are the results of the experiment used to analyze thermodynamic processes?

The results, such as changes in pressure, volume, and temperature, are recorded in tables and used to plot graphs. These graphs help analyze the behavior of gases under different conditions and test theoretical models, such as Boyle's and Charles' laws.

What are the expected outcomes from conducting this practical session on thermodynamics?

The expected outcomes include a better understanding of thermodynamic processes, the ability to calculate and graph relationships between pressure, volume, and temperature, and the ability to analyze and interpret experimental data to confirm theoretical concepts.
