Answer:
The probable grain-coarsening mechanism is : Ideal grain growth mechanism
(
-
= kt )
Explanation:
The plot attached below shows the time dependence of the growth of grain.
The probable grain-coarsening mechanism is : Ideal grain growth mechanism
the ideal growth follows this principle =
= kt
d = final grain size
= initial grain size
k = constant ( temperature dependent )
t = 0

Answer:
Check the explanation
Explanation:
The transferred energy calculations can be done using the equation:
This is when:
• power is calculated in watts (W)
• energy is calculated in joules (J)
• time is calculated in seconds (s)
it can also be calculated by utilizing the same equation but with different units:
• when energy is measured in kilowatt-hours (kWh)
• when power is measured in kilowatts (kW)
• and when time is measured in hours (h)
