Decrease the temperature and make it turn into ice.
Melting
you pee on it
freezing
WATER! If you put water in a cup and leave it in the freezer it will turn to an ice cube then if you leave it somewhere warm and cosy it will turn back to a liquid again. Try it for yourself even.
Place it in a freezer and allow it to freeze. Use of liquid nitrogen is a very quick method of doing so.
0o Celsius or 32o Fahrenheit.
When you put in the freezer
The cold allows it to bond in a way that is solid, because the molecules don't have enough energy to flow freely.
water vapor (gas state) can turn into water (liquid state) when cooled.
Chilling involves bringing something to a temperature that makes it colder, but does not turn it into a solid. Freezing, however, does turn the liquid into a solid. When a liquid is chilled, it is on its way to becoming frozen. For example, liquid water freezes at 32 degrees Fahrenheit example: freeze water (ice) floats above chilled water

no once the concrete gets hard it cannot turn into liquid state again but you can turn concrete powder into liquid by adding water :)
