Of course steady state condition occurs in almost any system but time it will occurs varies among system. for this kind of system, conduction, steady state conduction occurs when the temperature change from one point to the point is already constant. steady state is not achieved immediately because the heat travels and material will not be heated at the same way at the starting point.
Answer:
338 K
Explanation:
= 2.5 kg, c = 4189 J/(kg K), = 13.5 , = 22.5
= 0.5 kg, = 20
Heat loss by hotter water = heat gained by cooler water
cΔT = cΔT
c( - ) = c( - )
2.5 x 4189 x (22.5 - 13.5) = 0.5 x 4189 x ( - 20)
2.5 x 4189 x 9 = 2094.5 ( - 20)
94252.5 = 2094.5 - 41890
94252.5 + 41890 = 2094.5
136142.5 = 2094.5
=
= 65
= 65
But,
θ K = 273 + θ
= 273 + 65
= 338
The final temperature of the water is 338 K.
Answer:
It is True
Explanation:.
A commander assigns a zone reconnaissance mission when he seeks additional information on a zone before committing other forces in the zone. It is appropriate when the enemy situation is vague, existing knowledge of the terrain is limited, or combat operations have altered the terrain. A zone reconnaissance could include several route or area reconnaissance missions assigned to subordinate units.
When there is a temperature difference/Gradient, heat flows from a region of high concentration to region of low concentration.
<h3>Energy and Heat/Mass Transfer</h3>
Thermal energy flow from region of higher temperature gradient to region of low temperature gradient till equilibrium is reached.
When the hot metal is places in a cold water bath, there will be a temperature difference and by conduction(water conducts heat) the heat will travel in the water medium and circulate till equilibrium
