Increasing the temperature of a substance usually decreases its density because the molecules gain energy and move faster, increasing the volume they take up relative to their mass. This results in the substance expanding and becoming less dense.
No, a change in mass alone does not affect the density of an object. Density is determined by the mass of the object and the volume it occupies, so changes in mass need to be accompanied by corresponding changes in volume to affect an object's density.
Heat transfer can affect the fluid density at the nozzle exit, which in turn can impact the fluid velocity. An increase in heat transfer can lower the fluid density, resulting in an increase in velocity at the nozzle exit due to conservation of mass. Conversely, a decrease in heat transfer can raise the fluid density, leading to a decrease in velocity.
The density of molecules affects heat transfer by determining how closely packed the molecules are. Higher density means more molecules per unit volume, leading to more efficient heat conduction. Lower density results in slower heat transfer due to fewer molecules available for heat energy to be transferred through.
As water is heated, its density decreases. When water molecules are heated, they gain energy and move around more, causing the molecules to spread out and the water to expand. This expansion leads to a decrease in density.
No, density does not directly affect water temperature. Water temperature is primarily influenced by factors such as sunlight, air temperature, and geothermal heat. However, changes in temperature can lead to changes in water density due to thermal expansion or contraction.

it depends on what chemicals used
If an object has more density it takes longer for the heat to reach the center so it can start melting.
Heat (wildfires, volcanoes, urban heat sinks) affects global warming by adding more heat to the massive amount of heat that is already destroying our natural environments and ecosystems.
The denser a material, the better its conductivity. Gas is worse than solids.
