D is the answer. The thermo works as an insulator minimizing the heat loss to the environment.
The unit 'kJ' or kilojoules is a unit of measurement for energy. It is equivalent to the SI units kg·m²/s². When energy is divided with time, that unit is now in terms of work, which energy per unit time. The parameter kJ/s is equivalent to kW or kilowatts.
Work = 35,000 kJ/0.250 s = <em>140,000 kW</em>
-3 - 3(-2) = +3

Answer:
Chemistry reactions are used in art for the following processes;
1) Analog photography
The photographic paper used in analog photography react when exposed to light such that the image on the film stains the photopaper
A series of chemicals are further used to develop the images now carried on the paper and water is used to rinse of the chemicals after the other chemical processes are complete
The photopaper, now bearing the developed photo is hung for it to be dried
2) Paint used for painting consists of several chemicals, including, minerals that serve as pigment, oils that serve as carrying agent, a thinner to prevent the paint from turning to solid
An artist therefore combines different chemicals for a given paint task
3) In the sculpting process
An original sculpture is produced by the artist with the aid of clay or plaster, from the original sculpture, on which wax coatings and chemicals are used to make a replica mold.
Copies of the sculpture can then be made by pouring material into the mold
Explanation:
The particles of the solute leave each other and become surrounded by particles of the solvent.
