Answer: A. New, high-tech materials are used to make prosthetic limbs for  people who need them

Explanation:

Engineering is an immensely important science to us as humans for through its development of tools, machines, engines and structures, human lives have been made better in just about every field.

One of these fields is the medical field. In the past people who lost limbs could say good bye to a normal life or at least a semblance of one but now, due to advancements in Engineering, high-tech materials can now be used to make prosthetic limbs for people who need them.

Which of the following processes DOES NOT occur during the convective transfer of heat within a container of air? Group of answe
vovangra [49]

The volume of a warmed part of the air is reduced and its density increases.

Explanation:

In a convective form of heat transfer, the volume of a warmed part of air is not reduced and its density does not increase.

During convection, heat causes the warm part of the air to expand and its volume increases. When volume increases, density is reduced.

  • Convection is a form of heat transfer that involves the actual movement of particles of the medium.
  • It usually occurs in fluids i.e gases and liquids.
  • In convection, the cold part exerts a buoyant force on the warmer air below and causes it to rise.
  • As the warmer part is rising the cooler part replaces it and a convective cell is formed in the process.
