1 gm of water occupies how much volume in cm3 at 373K?

Answer 1

The density of water changes with temperature. However, at standard atmospheric pressure, when water reaches 373 K (which is 100 °C or the boiling point of water), it starts to turn into steam. The density of water just before boiling (still in the liquid state) is less than its density at room temperature (about 1 g/cm³ at 4 °C).

However, for most practical purposes, especially close to the boiling point, we can still approximate the density of water to be close to 1 g/cm³. This is because while the density decreases with temperature, the change is not extremely large until the water actually begins to convert into steam.

Therefore, at temperatures close to but not above the boiling point, 1 gram of water would occupy a volume close to 1 cubic centimeter (cm³), given that the density is approximately 1 g/cm³. Note that this is an approximation, as the exact volume could be slightly more due to the decrease in density with increasing temperature. But without specific density values at 373 K for liquid water, this standard approximation is commonly used.

Answer 2

At 373K, 1 gram of water occupies approximately 1 cm³ of volume as water has a density of 1 g/cm³ at this temperature.
