Answer:
Planet X = Uranus or neptune, Planet Y = Earth, Planet Z = Venus
Explanation:
Planet X = Both planets are similar in nature, with the atmosphere being a thick layer of hydrogen and helium, then a layer of water, ammonia, and methane deeper down, coupled with the fact that gravity is compressing it, producing heat, and with the help of the planet's own internal temperature, a chemical reaction is bound to occur, especially with ammonia and methane. Marvin Ross proposed that under such extreme conditions, hydrocarbons such as methane would actually separate, and that the carbon would then bundle up and be compressed into diamond.
Planet Y = As far as I've known Earth is the only planet in which water exists in three states that being:
Liquid (Which is well.. water)
Solid (Ice)
Gas (Water Vapor)
Planet Z = Venus matches the description being that of a planet that has an atmosphere of CO2 and clouds made of sulfuric acid, the thick CO2 atmosphere causes the planet to heat up at blistering 475 degrees Celsius by trapping heat that has entered inside in what we call the 'Greenhouse effect' effectively making it the hottest temperature planet in the solar system. The planet also experiences high wind speeds and and extremely high air pressure.
