Which types of heat transfer involve heat flow from hot objects to colder objects?
a.
convection, conduction, and radiation
b.
convection, but not conduction or radiation
c.
convection and conduction, but not radiation
d.
convection and radiation, but not conduction

The correct answer is Option A.

Explanation:

Heat transfer is defined as the process in which heat is transferred from high temperature to low temperature to maintain equilibrium.

There are 3 modes by which heat can be transferred, they are:

Thus, all these three modes involve the heat flow from hot objects to cold objects.

Hence, the correct answer is Option A.

coral.

explanation:

coral. many marine organisms that produce calcium carbonate shells or skeletons are negatively impacted by increasing co2 levels and decreasing ph in seawater.

practical process described pest part of scientific investigation.

because practical knowledge is powerful then therotical knowledge.
