**Is 4h20 gas or liquid?**

The compound 4H20 does not exist as a standalone chemical compound. It represents a hypothetical combination of four hydrogen atoms (H) and twenty oxygen atoms (O). In reality, the chemical formula H20 represents a molecule of water, which exists as a liquid under standard conditions. Therefore, it is more appropriate to discuss the state of matter of H20 rather than 4H20.

**State of Matter of H20 (Water)**

Water (H20) is a well-known and abundant compound on Earth, existing in all three states of matter: solid, liquid, and gas. The state of water depends on the temperature and pressure conditions.

1. **Liquid State:**
Under normal or standard conditions (at room temperature and atmospheric pressure), water exists as a liquid. Liquid water is colorless, odorless, and tasteless. It has a specific heat capacity, which allows it to absorb and store heat energy efficiently. This property makes water an excellent solvent and a crucial component for various biological processes.

2. **Solid State:**
When water is cooled below its freezing point (0°C or 32°F), it transitions from a liquid to a solid state, forming ice. Ice is a crystalline solid with a regular arrangement of water molecules. The hexagonal lattice structure of ice causes it to expand, making it less dense than liquid water. This expansion upon freezing is why ice floats in water.

3. **Gaseous State:**
When water is heated above its boiling point (100°C or 212°F) at atmospheric pressure, it converts into steam or water vapor, which is a gas. The gaseous form of water is invisible and can mix uniformly with other gases in the air. Water vapor is an essential component of Earth's atmosphere, contributing to weather patterns and the water cycle.

**Conclusion**

In conclusion, the compound 4H20 does not exist, but water (H20) exists as a liquid under standard conditions. However, it can also exist as a solid (ice) or a gas (water vapor) depending on the temperature and pressure conditions.

It can be either . gas and liquid are physical state of mater and when physical changes occur there is no change in the chemical properties ie 4H2O can occur in both gaseous , liquid and solid form
