Decide which components you wish to assess yourself. There is no set order in which you do this. you could, for an example assess one or two elements and skip the rest.
Answer and Explanation:
Internal Energy:
Internal energy associated to a system is the total amount of energy of a system excluding both the kinetic and potential energies as a whole for any external effects and is only accountable for any change in the energies of the system due to the internal order or states. It can be considered as that energy of the system essential to make it ready for any provided state.
Specific heat:
It is the specific amount of heat that is contained in a unit mass of any substance needed to bring about [tex]1^{\circ} rise in its temperature.
Entropy:
It can be defined as the degree of disorientation of the molecules or the extent of disorder of the system. It is the lack in thermal energy of the system to get converted into work (mechanical).
Temperature:
The measure of the heat intensity of a substance on a given standard scale.
Answer:
In a permanent magnet, the magnetic field comes from the motion of the electrons inside the material, or, more precisely, from something called the electron spin. The electron spin is a bit like the Earth spinning on its axis. The magnetic field is a vector, the same way the electric field is.

Answer:
Explanation:
For flow of heat through conduction , the formula is
Q = KA( T₂ -T₁ ) / d where K is thermal conductivity of material , A is surface area , T₂ - T₁ is temp diff .
Thermal conductivity of aluminum is 205 W /m.s
Surface area of cane = 2π r² + 2π r h where r is radius and h is height of cane .
A = 2π r ( r + h )
= 2 x 3.14 x 1.3 x .0254 ( 1.3 x .0254 + 4.83 x .0254 )
= .20736 ( .033 + .12268 )
A = .03228 m²
thickness d = .12 x 10⁻³ m
Putting the values ,
Q = 205 x .03228 x ( 25 - 4 ) / .12 x 10⁻³
= 1158 x 10³ J /s
