The warmer the water is the less dense it is but the colder it is the more dense it is. A2: therefore, warm water rises above cold water
The temperature and the salinity affect water's density.
the temperature and the salinity
The temperature and salinity of seawater determine its density. Water gets denser as it gets saltier and reaches a maximum density at 4 °C. Salinity does affect the boiling point and freezing point of water, but not its temperature.
The temperature of the water and the salt content of the water.
Temperature & salinity.
The density of water increases as its temperature increases from 0 deg C to 4 deg C (the anomalous expansion phase). Above 4 deg C, the density decreases with temperature.

Deep currents form where the density of ocean water increase so, water density depends on temperature and salinity. I hope I helped you =)
Only by virtue of the change in density of water. As water expands with temperature rising its density falls slightly so the height of water for a given pressure will increase slightly.

I assume you mean "affect". Water density can be affected by impurities. Assuming the water is pure, it can be affected by temperature, pressure, and isotopic composition.
This is very unspecific. Density is mass over volume, so I would assume that the temperature of water around it would not effect the mass or volume of the ketchup packet.
