whether solid od gas absorbs more heat energy
Answers
Answer:
solid
Explanation:
because it retains for longer period of time and donot get scattered.
Answer:
The control of heat at the nanoscale provides interesting possibilities for moving heat from locations where it is not wanted, or for using the buildup of heat in nanoparticles to drive chemical reactions more efficiently.
The Lear group in the Department of Chemistry has a long-standing program that looks at photothermal heating of nanoparticles – nanoparticles that absorb light strongly, and then efficiently converts this light to heat. As the thermal energy builds up, it is dissipated into the local environment, where it can drive catalytic reactions, ablate cancer cells, or decompose polymers.
In the process of studying this behavior of nanoparticles, they observed that driving reactions that absorbed heat resulted in more efficient cooling of the particles.
