![]() ![]() You can also choose one of the objects from the list to see if it floats or sinks. In the beginning, the density of hot water is quite high, so everything should sink, but at some point, the density will decrease to the point where the object begins to float! Insert the value of salinity and temperature at which the object began to float in the water density calculator, and you should be able to estimate those densities with relatively good precision! You can quickly evaluate the temperature of water while it is cooling down. You can start by heating your mixture (e.g., in a microwave), then submerging your objects in it. Check out the Advanced mode to see how much pure water and salt you need to obtain salt water with a specific density. Although changing the external pressure is difficult, you can create a liquid with known salinity and control its temperature. The same density of water is 1.0249 g/ml or 63.982 lb/ft³.īut this is not the end! Perform your own experiment at home – take a few objects with an unknown density (but more or less equal to the value for the density of water, i.e., 1000 kg/m³).
