Will density of metal increase with temperature and cold working?

I have a metal strip (20 x 180 x 1 mm) formed by electrodeposition. The metal strip was annealed to 935 degree centigrade (microstructure showed increase in grain size). The strip was further cold rolled to (30 x 360 x 0.5 mm) on a rolling mill.

1. Will the density increase or decrease after annealing ?

2. Will the density increase or decrease after rolling ?

3. Also provide any references if available.
