The transfer of energy from one region of the atmosphere to another is of great importance in meteorology for it affects the weather. calculate the heat needed to be supplied to a parcel of air containing 1.00 mol air molecules to maintain its temperature at 300 k when it expands reversibly and isothermally from 22 dm3 to 30.0 dm3 as it ascends.

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.

it is stable as it is in group 0 which have full outer shells of electrons
