Answer:
The average thermal conductivity of the material at this temperature range is 3*10^(-9) W/mK.
Explanation:
The heat flow through this area of the metal panel can be expressed as:
being A the surface area, k the thermal conductivity, T2 and T1 the temperatures in each side and Y the thickness of the metal panel.
We have to rearrange the equation to clear k:
The average thermal conductivity of the material at this temperature range is 3*10^(-9) W/mK.

<span>the
most important feature in determining the phase of a given organic compound is
pressure. ransfers of organic compounds
between phases are controlled by molecular interactions (intermolecular bonding)
in the two phases between which transfer is occurring. This is governed
by temperature and pressure</span>
Answer:
(C) substance B is not involved in the rate-determining step of the mechanism but is involved in subsequent steps.
Explanation:
A. Is incorrect because if the order of the reaction with respect B was one then the rate would increase by the same multiple that B is increased by.
B. If B is reactant then it must be involved in the mechanism of the reaction and in the formation of the product
D. If B was a catalyst then increasing it's amount would affect the rate
E. That is just factually untrue. Effect of reactants on rates can only be found experimentally, not stoichiometrically.
To find the area of something you have to multiply the length x the with x the height. Or if it gives to the base then you multiply the base x the height.
1.Heat:Heat can cause rock to melt,forcing real changes in its chemical and physical makeup;forcing some elemental components to chemically react with each other,both internal and external,chemical components to form entirely new material.
