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!

odds are decent that your handwriting right now looks a little bit different than it did five years ago, and will look different again in five more. when i look back through my notebooks from middle school to now, i see a long, slow progression from meticulous and teeny letters to bigger, sloppier ones, plus a few side detours: sometime in high school, for example, i decided those loopy cursive lowercase f’s were just the coolest, adopting them as the lone rep for cursive in my otherwise all-print handwriting.

explanation:

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."
