Spherical shapes are the most efficient at containing heat. This is because a sphere has the smallest surface area relative to its volume, which minimizes heat loss through conduction and radiation. Additionally, spherical shapes promote even distribution of heat throughout the object.

Why is rice a good insulator?
Rice is a good insulator because it is a poor conductor of heat and electricity. Its structure contains air pockets that reduce the transfer of heat, making it effective in preserving warmth or preventing heat loss. Additionally, rice can mold and conform to the shape of an object, providing a snug fit for insulation purposes.
What shape keeps heat in the best?
Spherical shapes are the most efficient for retaining heat, as they have the lowest surface area-to-volume ratio. This means there is less surface area for heat to escape from compared to other shapes like cubes or cylinders.
Which contains more heat thermal energy an iceberg or a port of boiling water?
A pot of boiling water contains more heat energy than an iceberg because the water in the pot is at a higher temperature than the ice in the iceberg. Heat energy is directly related to temperature, so the higher the temperature, the more heat energy an object contains.
What contains more heat energy?
A cup of boiling water contains more heat energy than a cup of lukewarm water because the boiling water is at a significantly higher temperature. Heat energy is directly related to the temperature of an object.
Which sate of matter is best as a thermal insulator?
Gases are generally better thermal insulators than solids and liquids due to their lower density and poorer thermal conductivity. Air is one of the best thermal insulators because it is a poor conductor of heat and does not have a definite shape, allowing it to fill spaces and reduce heat transfer.
When heat is transferred to a substance describe why the temperature goes up?
The best answer is: Because heat has been transferred to the substance, and it now contains more of it.
What is the shape called that contains text in a cartoon?
The shape that contains the text is often called a speech bubble or Callout.
Why does a ovary have such a shape?
Even though a woman will only ovulate a few hundred times in her lifetime, each ovary contains hundreds of thousands of gametes (egg cells). As such, a rounded shape is structurally best in terms of strength - no sharp sides or edges to easily rupture - and carrying capacity: for a given size, a spherical shape contains the greatest volume.
What cup contains more heat?
Dark cups contains more heat and loses it at the smallest rate than the silver cups.
Is yarn conductor of heat?
Unless your fibre contains metal, it has no heat conductivity.
What type of metal pot is best for boiling water?
Copper transfers the greatest percentage of heat to the contents of the pot (water). As for the shape of the pot ..... lower and about 1" wider on all sides than the heat source.as wide as the heat source.
How do you make silly bands?
first you need rubber string then some heat like a lighter then you put the string in a shape and with the heat put it together and you get a shape! It may not be the shape you want but it will be bracelet!
How can a shape physical change?
by the addition of heat

Why do you heat hair curlers?
The heat sort of "sets" your hair in the shape your curlers make it
Which shape always contains only right angles?
a rectangle
What is an advertisement that contains different sizes of the same shape?
pejises
