What happens to water when it warms above 4 °c? it contracts. it forms ice. its density decreases. its composition changes.

OPTION(c)

Water when it warms above 4 °C Its density decreases.

Explanation:

Since, temperature and density of water are inversely proportional to each other i.e when the temperature of water increases ,the density of the same hence decreases and vice versa.

At 4°C water has attained its most stable state and so has the maximum density. As the temperature warms up above 4°C the molecules of water begin to expand and hence density decreases with the increase in temperatures and contracts with the decrease in temperature

Hello~

Llamalover here!

Its density decreases, i took the quiz!

Explanation:

Hope this helps!

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.
