Answer: At temperature of 269 K the gas would occupy 1.33 L at 217 kPa
Explanation:
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,
where,
= initial pressure of gas = 147 kPa
= final pressure of gas = 217 kPa
= initial volume of gas = 1.8 L
= final volume of gas = 1.33 L
= initial temperature of gas =
= final temperature of gas = ?
Now put all the given values in the above equation, we get:
Thus at 269 K temperature the gas would occupy 1.33 L at 217 kPa

Hello! This is actually one of my favorite topics to talk about, so I’ll try to sum it up.
Bohr’s model is the one most commonly used in school settings because of the way electrons are classified based on energy capacity. Higher energy electrons are located at lower primary and secondary energy levels, and it helps with comprehension. This model does closely mimic stellar phenomena, and is also similar to rungs on a ladder, with the ground being the nucleus.
Schrödinger’s model is the newest model, published in the 1920s. His model encapsulates a “cloud” of electrons orbiting the nucleus, lacking a definite structure of order. Unlike Bohr’s model, Schrödinger’s illustrates the rapid fluctuations of energetic capacity of free electrons, as they act very erratically. Instead of classifying the electrons individually, Schrödinger created a system of descriptive formulae that tell the “chance” of an electron being in a certain area of the cloud. For this reason, many curriculums choose to adapt the Bohr model in their teaching, especially in lower grade classes, to help with overall comprehension, and, then, over time, integrate Schrödinger methodology to help “modernize” the quantum concept.
Hope this helps!
