Explanation:
Conduction:
Heat transfer in the conduction occurs due to movement of molecule or we can say that due to movement of electrons in the two end of same the body. Generally, phenomenon of conduction happens in the case of solid . In conduction heat transfer takes places due to direct contact of two bodies.
Convection:
In convection heat transfer of fluid takes place due to density difference .In simple words we can say that heat transfer occur due to motion of fluid.

Answer:
The answer which is a calculation can be found as an attached document
Explanation:
Answer:
Percent Elongation = 52.72%
Percent Reduction in Area = 64%
Explanation:
First we find percent elongation:
Percent Elongation = {Final Gage Length - Initial Gauge Length/Initial Guage Length} x 100%
Percent Elongation = {(4.20 in - 2.75 in)/2.75 in} x 100%
<u>Percent Elongation = 52.72%</u>
Now, for the percent reduction in area:
Percent Reduction in Area = {Final Cross Sectional Area - Initial Cross Sectional Area|/Initial Cross Sectional Area Length} x 100%
Percent Reduction in Area = {π(0.3 in)² - π(0.5 in)²/π(0.5 in)²} x 100%
<u>Percent Reduction in Area = - 64%</u>
here, negative sign shows a decrease in area.
