how do the principles of convection conduction and radiation explain how the water in the saucepan gets hot

specific gravity is the density of a substance divided by the density of water. since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density

so "c" is the answer

plz give brainliest

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.
