These are changes in physical state, which are physical changes.
Because a central heating model does not have any electrons travelling through wires but have water. If a wire broke in a electric circuit , then if you're not going to turn off the circuit you would get electrecuted. In a central heating system, if it would break water will leak and nothing will hurt you or anything and you won't get electrecuted.
By heating up to melting point.
Burn it to produce electicity, or burn it in a water heater for central heating, or burn it in a stove or open fire in a home
The liquid has been super cooled. Any disturbance will result in the water solidifying. The opposite of this is called super heating which can be done in a microwave. It is VERY DANGEROUS as when the container is touched the water will turn to steam and chuck out boiling water.
It turns into a vapor, and you do it by heating it to or past the boiling point.

yes, the breaker just controls the heating elements
By locating the thermostat and turning it down
turn into a solid

freez the water. after freezing it will be ice then you can turn a glass of water upside down without spilling the water.
solar water heating systems. These have cold water fed to them, normally on the roof. The head of the day warms the warm, not to the extent it can be used for heavy washing but certainly to a above tepid state. It then pumps it to a storage tank. when you turn on the hot water demand in teh house of building the water is already warming and this save gass, oil or electric as the boiler does not have to warm water from its cold state. It down technically by the heat of the day which is in itself free
You should check and adjust the heating temperature, then turn on the cold water to fill the tank.
No. Cooling will though. Think about, if you heat up water will it turn to ice (solidfy)?
never
heating of water by the sun's energy which increases the temperature of the water causing some of the water to turn into water vapour at a temperature below the water's boiling point temperature.
