Question

Answer in Brief:How does the state of water change with change in temperature

Answer 1

1. Water exists in three states i.e. solid, liquid, and gaseous states.
2. In liquid states it exits as water, in solid-state, it exists as ice and in the gaseous state, it exists as water vapor.
3. When we increase the temperature the water in the solid-state which is called ice changes into a liquid state and on further heating the water in the liquid state changes into the gaseous state.
4. This happens because when you provide heat energy to the water the particles of water start moving away from each other because of the increasing kinetic energy which results in the increase in intermolecular spaces and a decrease in the intermolecular force of attraction, then the state changes from solid to liquid and further from liquid to gas
5. On cooling the temperature gaseous state changes to a liquid and further liquid state changes to a gaseous state.
