Sample Non-Regents Questions
At 273 Kelvin, 400 mL of a sample has a pressure of 101.3 kPa. If the pressure falls to 50.5 kPa, at what temperature will the sample have a volume of 551 mL?
Answer
The explanation of this question is shown on this card and the next card.
1. This equation discusses temperature, volume, and pressure. Therefore, we will use the Combined Gas Law formula.
2. Let’s figure out the values:
• P1= 101.3 kPa • V1= 400 mL • T1= 273 Kelvin
• P2= 50.5 kPa • V2= 551 mL • T2= ?
