Question

how can you converter water into ice​

Answer 1

Answer:

Adding heat can cause ice (a solid) to melt to form water (a liquid). Removing heat causes water (a liquid) to freeze to form ice (a solid). When water changes to a solid or a gas, we say it changes to a different state of matter. Even though the water's physical form changes, its molecules stay the same.

Answer 2

Water can be converted into ice by storing it in a place which has atleast a minimum temperature of -4℃. Now, this would sound ridiculous that if water can be frozen at 0℃ then why on Earth we require a minimum of -4℃. Well, the reason is that only pure/distilled water can freeze at 0℃ but for an impure water/tap water we need atleast a minimum temperature of -4℃ because the impurities makes water more resistant to freeze thus creating a depression in freezing point.

To sum up:

Distilled water can be converted into ice by storing it at a temperature of 0℃ while an impure water needs a minimum of -4℃ to convert it into ice.
