Trouble Solving Volume of Condensed Water

AI Thread Summary
To determine the volume of condensed water from 3.00×10^4 cm^3 of steam at 300 degrees C and 10.0 atm, the ideal gas law pV=nRT can be applied. The user is confused about rearranging the equation for their specific needs and seeks clarification. There is also a question raised about the relevance of quantum physics to this problem. Additionally, a request for the rearranged equation is made to facilitate understanding. Understanding the ideal gas law and its application is crucial for solving the volume of the liquid water.

I'm having some trouble getting started on this one:

3.00×10^4 cm^3 of 300 degrees C steam at a pressure of 10.0 atm is cooled until it condenses. What is the volume of the liquid water? Give your answer in cm^3.

I figure you use pV=nRT to solve. I've been trying to rearrange it, but am confused. Any help would be greatly appreciated. Thanks.

Firstly, why is this is Quantum Physics?

Secondly, why don't you show us the equation that you get when you rearrange it?

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
