Water is in liquid state at 25 degrees Celsius. This is the temperature at which water transitions from a solid (ice) to a liquid state.
It changes state at 0 degree(freezing point), which forms ice, and 100 degree(boiling point), where it turns into vapour. Chemists are trying to create 'ultra pure water', which has almost no foreign substance in it exept H2 and o, and it will freeze at 40 degree celcius!
Under o 0C water is a solid; between 0 0C and 100 0C is a liquid; over 100 0C is a gas.
Water evaporates faster at 100 degrees Celsius compared to 200 degrees Celsius because at 100 degrees Celsius, water reaches its boiling point and undergoes a phase change from liquid to gas. At 200 degrees Celsius, water is already in the vapor state, so there is no further evaporation taking place.
The total amount of substance will remain the same when 100 grams of ice melt into water. Only the physical state of the substance changes from solid (ice) to liquid (water), but the mass remains constant.
The boiling point of water is 100 degree celsius. Therefore water changes in to vapor after 100 degree celsius. Therefore the physical state of water at 250 degree celsius is "Gas".
At 100ºC and standard pressure, the physical state of water is both liquid and vapor in equilibrium.
It's physical state is gas
At 250 degrees Celsius, water is in the form of steam or vapor. This is above the boiling point of water (100 degrees Celsius), causing it to transition from a liquid to a gas state.
At 100 degrees Celsius, chlorine is in the gaseous state. Chlorine is a diatomic molecule normally found as a gas at room temperature and pressure.

100 g Steam at high temperature (>100°C) and pressure (>1 Bar)
At 35 degrees Fahrenheit, water is in a frozen state. To boil water, you need to increase the temperature to 212 degrees Fahrenheit (100 degrees Celsius) at sea level. This increase in temperature is necessary to overcome the intermolecular forces holding water molecules together in the liquid state.
