Answer:

Explanation:
Given data:
Diffusion constant for nitrogen is 
Diffusion flux 
concentration of nitrogen at high presuure = 2 kg/m^3
location on which nitrogen concentration is 0.5 kg/m^3 ......?
from fick's first law

Take C_A as point on which nitrogen concentration is 2 kg/m^3

Assume X_A is zero at the surface


Answer:
Carnot heat pump
Explanation:
Carnot heat pump is an ideal heat pump in which all processes are reversible and that consume minimum amount of work to and produces maximum amount of heating effect compare to all real engine.And that is why COP of Carnot heat pump is more as compare to real heat pump.
All real heat pump are not perfectly reversible heat pump So this is also called irreversible heat pump .Due to irreversibility the COP of irreversible heat pump is always less than the COP of Carnot heat pump.
Problem solving is the act of orderly searching for solutions to problem
The correct option that involves approaching a problem in a new way is the option;
Creative thinking
The reasons why creative thinking is the correct option is given as follows;
Finding new ways to approach a problem, involves considering alternatives to already known approaches to the problem
Given that the options to be considered are to be options which have not been applied, then the process does not involve;
Context: Which looks at the variables that relate the problem with setting or circumstance that aid understanding of the problem
Critical thinking; Which is based on the analysis of the known facts, but the new proposals are required
Perseverance; Which involves adherence to a particular option despite delay or difficulty
However;
Creative thinking; Creative thinking involves the consideration of a situation thing or problem in a new way or by approaching a task differently than what was considered a regular approach, which involves finding an unused or imaginative approach to a problem
Therefore;
The option that involves finding new ways to approach a problem is <u>creative thinking</u>
