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.
Answer:
16.53 pounds
Explanation:
this type of problem needs convertion method we need to convert from grams to pound.
True, cracking distillation is one process used to break hydrocarbons into smaller and more useful parts. This is achieved by using high temperatures and pressures with a catalyst. The most common catalyst used are the zeolites.
The answer is "A. a pure substance can be separated by chemical means, while a mixture can be separated by physical means". A pure substance only has one type of substance, whereas a mixture has more than one. A pure substance therefore, can only be separated chemically, because it is not two things mixed together, whereas a mixture can be separated physically because there are multiple substances.
Answer:
Higher melting and boiling points signify stronger noncovalent intermolecular forces. Consider the boiling points of increasingly larger hydrocarbons. More carbons means a greater surface area possible for hydrophobic interaction, and thus higher boiling points.
