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".
Zinc hydroxide is a solid state compound at room temperature.
IT IS SOLID (at room temperature).
K is +1 O is -2 H is +1
Ammonium hydroxide is a weak base composed of ammonia and water, while potassium hydroxide is a strong base containing potassium and hydroxide ions. Ammonium hydroxide is commonly used in household cleaning products, while potassium hydroxide is used in industrial processes such as soap-making and as an electrolyte in alkaline batteries.
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.
Sodium hydroxide is a solid at room temperature. It is a white, odorless, and highly caustic substance commonly known as lye.
