If density ussualy increases with decreasing temperature why does ice float on liquid water

As the temperature becomes colder, the water molecules lose energy and move less. The hydrogen bonds that form when water freezes into ice allow the molecules to be spaced farther apart, making them take more space, decreasing the overall density and making it float in the water.

I hope this helped :)

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.

i was thinking 4.0 v hope this
