Pick one of the two options to fill in each blank:  If a submarine wants to rise back up to the surface of the water, it  _______________ (decreases / increases) its _____________(mass / volume).

Decreases  its mass

Heating a fluid makes the volume (increase/decrease), which causes density to (increase/decrease) and for the fluid to (float/sink).
heating a fluid increase volume, decreases density, and fluid will float
