WebThis makes hot water less dense than room temperature water. Since hot water is less dense, it floats on the room temperature water. Is water at room temperature is a liquid? Ans. (a) Water at room temperature exists as liquid because its melting point is below room temperature while boiling point (100º C) is above room temperature. WebJun 15, 2013 · The bag should be submerged in cold tap water, changing the water every 30 minutes so it continues to thaw. Small packages of meat, poultry or seafood — about a pound — may thaw in an hour or less. A 3-to 4-pound package may take 2 to 3 hours. For whole turkeys, estimate about 30 minutes per pound. If thawed completely, the food must …
