Answer:

True

Explanation:

First, it must be known that heat transfer is equal to the temperature difference divided in the thermal resistance, so the fouling that is a layer of dirt that accumulates on the surface of the heat exchanger over time this layer ends up becoming an additional thermal resistance, increasing the total thermal resistance, giving a drop in the rate which the heat is transferred, so in this case the statement would be true.

What issues does society try to forget in order to not have to deal with them ?
velikii [3]

Answer: Homelessness, Drug addiction, Mental Illness, Climate change.

Explanation:

Society would rather be ignorant to/ ignore all of these realities so they do not have to stop specific behaviors or actually acknowledge other people and help. Sometimes people are so stressed out about their own lives, they can not bare another persons issues. People are ignorant to climate change because correcting it requires massive changes and society is selfish and unwilling to change.
