Question

What happens to water when it warms above 4 °C? It contracts. It forms ice. Its density decreases. Its composition changes.

Answer 1

Answer:

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
