Question

This picture represents a sample of gas at a pressure of 1 atm, a volume of 1 L, and a temperature of 25 °C. Draw a similar picture showing what would happen to the sample if the volume were reduced to 0.5 L and the temperature were increased to 250 °C. What would happen to the pressure?

Accepted Answer

Welcome back everyone in this example we have an image below with a 1.5 liter gas sample at 1.5 A t. M. S. And 30 degrees Celsius. We need to determine what would happen if the volume increases to three liters and the temperature decreases to 10 degrees Celsius. So we want to recall our ideal gas law where pressure times volume is equal to the mold of our gas, N times the gas constant R times the temperature in kelvin. And we can see that pressure and volume are directly related to temperature. Now, if we were to isolate volume, we would say that volume is equal to the most of our gas divided by pressure times R gas constant R times temperature. And so we would see that volume is inversely proportional to pressure. And so what we would say is that according to our prompt, if we increase our volume to three liters, we would say that therefore our pressure which is inversely related to volume is going to decrease. Now on the other hand, if we increase or sorry, decrease Our temperature to 10°C, we would therefore say that because temperature is directly related to pressure, we would also decrease our pressure. And so for our final answers, we would say overall pressure decreases for the sample. And so for our final answer we can say that pressure decreases. So I hope that everything I explained was clear. If you have any questions, please leave them down below and I will see everyone in the next practice video
