Question

a group of students is studying heat transfer by placing a hot block of metal into a styrofoam cup of room temperature water. which method of heat transfer are the students studying?
a radiation
b convection
c conduction
d thermal energy

Explanation:

Conduction is heat transfer through direct contact. Here, the hot - metal block is in direct contact with the water, so heat is transferred by conduction. Radiation is heat transfer through electromagnetic waves, and convection is heat transfer through the movement of fluids (in a bulk - motion sense). Thermal energy is the total internal energy of an object due to its temperature, not a method of heat transfer.

Answer:

C. conduction
