The green solid P is likely copper(II) oxide (CuO). When dilute nitric acid is added to CuO, it forms copper(II) nitrate (Cu(NO3)2) which is blue in color (solution Q). The gas R formed is likely nitrogen dioxide (NO2) which reacts with lime water (Ca(OH)2) to form calcium nitrate (Ca(NO3)2) and a white precipitate of calcium nitrate.
When the blue solution Q is evaporated to dryness, copper(II) nitrate will crystallize out as solid crystals. These crystals can be collected and further processed or used in various chemical reactions.

The blue solution when evaporated to dryness, will give a blue residue of copper nitrate.
P is copper ( metal )
Q is copper nitrate solution
R is nitric oxide
