Why is liquefied natural gas carried aboard ships in giant spherical containers?
A sphere has the lowest surface to volume ratio of any solid body. Since liquefied natural gas must be kept at a temperature far below ambient temperature, and since heat can enter the storage container only through its surface, using a spherical container minimizes the energy that must be expended to maintain the stored liquefied natural gas at a low temperature.
Why must cooked food be kept hot or cold but never at room temperature?

At what temperature should hot food be held?
You need to keep it at 180 degrees f. or above. Food safety standars are that Hot foods can be held at or above 140 degrees f. for no more than 4 hours. cold foods must be kept at or below 40 degrees f. keep in mind that these are holding temperatures only and food should be cooked to the appropriate temperature for that specific food.
