Question #44ca3

Answer 1

Basically its a situation where no temperature change occurs in a reaction and the vessel (environment) temperature containing the reaction stays the same.

Explanation:

Its related to an ideal gas because with an ideal gas we assume that the internal energy of the gas is directly related to the temperature. This means we can calculate the precise energy of the gas based solely on it's temperature and can therefore influence it's energy based upon the use of pressure.

This (sort of) explains why Carbon can exist as both graphite and Diamond at the same temperature - if we change the PRESSURE of the system where the carbon is, we can change its energy and thus its state (or molecular shape).

Hope this helps!
