Solid state in room temperature.
At room temperature, copper hydroxide is solid.
Potassium hydroxide is a white solid at room temperature, commonly known as caustic potash. It is highly corrosive and hygroscopic, meaning it readily absorbs water from the atmosphere. When dissolved in water, it forms a strongly alkaline solution.
NO!!! Potassium hydroxide contains;- 1 X potassium(K) 1 x Oxygen (O) 1 x Hydrogen (H). To give the formula 'KOH'. NB Helium is 'He'. It is the most unreactive element of all. It remains in the monatomic gaseous state. So it is not part of potassium hydroxide.
Zinc hydroxide is a solid state compound at room temperature.
Hydrogen's physical state at room temperature is a gas.
At room temperature, copper hydroxide is solid.

Potassium is in thee solid state at standard temperature and pressure, which is sometimes loosely called "room temperature".
IT IS SOLID (at room temperature).
Zinc hydroxide is a solid state compound at room temperature.

Ammonium hydroxide is a weak base with the formula NH4OH. It readily forms when ammonia is dissolved in water but it can only exist in aqueous solution. Trying to isolate it will cause it to revert back to ammonia and water. Potassium hydroxide is a strong base with the formula KOH. It will readily dissolve in water but can also exist in a pure state, which takes the form of a white solid under normal conditions.
Potassium trioxide is not a known compound. Potassium typically forms compounds with an oxidation state of +1, +2, or occasionally +3. It is more common to see potassium in compounds such as potassium chloride (KCl) or potassium hydroxide (KOH).
Hydrogen's physical state at room temperature is a gas.
The state of matter of chloride is gas.Cl2(g) All diatomic elements are gases except for I2(s), a solid, and Br2(l), a liquid.
