Explanation:

A new Material is formed.

Basically, Chemical changes differ from Physical changes because in chemical changes, Substances have the ability to become a different substance.

Example:

Water to ice is a physical change because it is still water despite being a solid from liquid.

A Magnesium strip placed in CuSO4 solution made the Mg strip turn into a new substance which is MgSO4. this is a Chemical change because Mg has now become a different substance called MgSO4.

Heat is transferred by conduction through a wall of thickness 0.87 m. What is the rate of heat transfer if the walls thermal con

erik [133]

Explanation:

The given data is as follows.

Thickness (dx) = 0.87 m, thermal conductivity (k) = 13 W/m-K

Surface area (A) = 5 $m^{2}$ , $T_{1} = 14^{o}C$

$T_{2} = 93^{o}C$

According to Fourier's law,

Q = $-kA \frac{dT}{dx}$

Hence, putting the given values into the above formula as follows.

Q = $-kA \frac{dT}{dx}$

= $-13 W/m-k \times 5 m^{2} \times \frac{(14 - 93)}{0.87 m}$

= 5902.298 W

Therefore, we can conclude that the rate of heat transfer is 5902.298 W.
