Answer:
equal to
Explanation:
This question is depicting the LAW OF CONSERVATION OF MASS/MATTER, which states that matter can neither be created nor destroyed. Hence, in an isolated system, the original mass of the reactants must be EQUAL TO the final mass of the products formed.
In other words, the law states that no matter the change in chemical composition of the reactants in a chemical process, the mass does not change or it remains constant.
7 protons, 7 neutrons, and 7 electrons
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.
