<em>From the above options, the best </em><em>Thermal insulator </em><em>will be a </em><em>Plastic cup.</em>
Option (b);
<u>Explanation</u>
Thermal insulators resist to conduct energy or reduction of heat transfer when objects come across in contact with radiation or higher heat object. To conduct energy we need metal or those materials which contain free electrons in it to move from one metal to another.
Plastic doesn't have metallic character so it will resist the heat up to some threshold. Mostly this material is used in separating two current-conducting material. There are many other examples of thermal insulator such as Rubber, fabrics, paper, wood, wool.
Answer:
How stable is the matter that the energy is transferring to? How volatile is the thermal Resistance?
They use natural resources like sunlight water they need soil water and sunlight to grow the stem should be pliable and firm and will have a green cast on the inside
You would have to evaporate the water to get just the sugar
