    Hi all!

    I've got this question (GCSE one), and I think I got somewhat of an answer - please check it!

    The question:

    "Suppose there are two gas clouds in space, and both have the same pressure but cloud A is much hotter than cloud B. What can you say about the density of the two clouds."

    Now the answer I thought is that the density of cloud A (the hotter one) will be lower than B. The reason being is that as the temperature is higher, the particles will have more kinetic energy, thus spreading out over a larger area -the particles cover a larger area, the density (amount of particles in a specific area) must therefore decrease.

    However, the doubt I have is that, even with a constant pressure, won't the cloud with a higher temperature have a lower density because the particles will be in a lower volume (most collisions)??

    Please help, I am very, very confused!:confused::confused::confused:
