Either of these might be used. "Which" is the better choice if you are supposed to choose from a limited set of cups (this metal cup or this thin ceramic cup or this thick ceramic cup). If you mean the choice of all existing cups, you might "what cup" or more appropriately "what kind of cup."
Paper cups trap heat through a process called conduction. When hot liquid is poured into the cup, the heat is transferred to the paper material, which then insulates the liquid and helps retain its temperature. Additionally, the air pockets within the paper provide additional insulation, further trapping the heat inside the cup.
The best tool for measuring the volume of a glass is a liquid measuring cup. Simply pour water into the glass from the measuring cup and read the volume markings on the cup to determine the volume of the glass.
Insulates means to protect or shield something from heat, cold, sound, or electricity by using a material that does not conduct these elements well. It helps to regulate temperature and prevent energy loss in a controlled environment.
Wool is known for its excellent insulating properties, as its fibers can trap heat close to the body. Other good insulators include down feathers and certain synthetic materials like polyester and nylon. Ultimately, the best fabric for insulating heat will depend on the specific application and level of warmth needed.
The subcutaneous layer, also known as the hypodermis, insulates the body from extreme temperatures by storing fat that helps maintain body temperature. This layer is located beneath the dermis and serves as a protective barrier against heat loss in cold conditions and heat gain in warm conditions.
wool insulates heated water best because woll is the best insulator.
Here are some sentences.This fiber insulates the roof.The quilt insulates you from the cold.
One who, or that which, insulates., The substance or body that insulates; a nonconductor.
You're talking about holding the temperature of the water, right? As far as containing the liquid, they're about equal...but a styrofoam or double-wall plastic cup would hold temp better than a glass cup which would work better than a single-wall plastic cup.
Styrofoam insulates better than a single layer of plastic. If, however, you have one of those plastic cups that have an outer and an inner "wall" with a sealed air space in between, that should work better than the Styrofoam.
It insulates the fish from the cold air above.
aluminum foil is going to be the worst insulater, paper is a good insulater but not the best, so the best is cotton.
It insulates you
