Three types of Heat Transfer

2
New cards

➢Conduction

occurs through molecular collisions (material must be in thermal contact)

from a region of high T to low T

3
New cards

Convection

• involves actual mass transport of fluids

• heat transfer by the actual motion of the fluid

• HOT fluids displace COLD fluids

4
New cards

COLD

HOT fluids displace *** fluids

5
New cards

Natural and Forced

Two kinds of Convection

6
New cards

•Natural

difference in density due to thermal expansion

7
New cards

•Forced

by blower/ pump

8
New cards

➢Radiation

All objects radiate energy continuously in the form of electromagnetic waves due to thermal vibrations of the molecules (temperature) Radiation does not require physical contact
