Gas in an atmosphere that absorbs and emits radiation within the thermal infrared range is greenhouse gas like methane, CO2 etc...

Yes, water releases green gas, water vapor is most dominant green gas.

Plaster of Paris is made from heating gypsum above 130 centigrade.

Combustion is a unit process as the definition goes unit process involves both physical and chemical change and combustion is a chemical change so it is unit process where as unit operation is just a physical change like drying, crushing etc...
