When a substance changes state, its density can change. For example, when a substance transitions from a solid to a liquid state, its density usually decreases. Conversely, when a substance transitions from a gas to a liquid state, its density typically increases.
It contracts
Condensation
it gets coldit gets cold
When the material gets closer to the core it gets hotter and more dense.
Density increases until 4 degrees of celcius.Then decrease again.
He gets up and runs to the ocean to cool down.
Specific gravity is otherwise known to be "Relative Density". It is the ratio of the density of a substance to that of water as water has been taken as standard. So though volume gets changed there is no chance to get change in the relative density as it is the characteristic property of the substance.
When the density of a fluid gets hotter, it usually decreases. This is because as the fluid gets hotter, its molecules gain energy and move farther apart, causing the fluid to expand. This expansion leads to a decrease in density.
One of the factors affecting density is temperature. Because the particles spread more apart when heated, the hotter the substance is, the less dense the substance gets. another one has six letters that describes all of it is energy!!
they try to find a cool place to reside(shelter)
There will be a warning saying that it must cool down for it to work.
