Answer: The given statement is false.
Explanation:
Heat flux is defined as the flow of heat or energy per unit time in per unit area. S.I. unit of heat flux is watts per square meter.
Heat flux is represented by the symbol .
So, it means heat flux is not measured in watts only as it includes per unit area also.
Therefore, we can conclude that the given statement heat flux, or the rate of heat transfer per unit area, is measured in watts (Watts) only, is false.
Answer: 0.011 moles.
Explanation:-
To calculate the moles, we use the equation:
Given :
Mass of copper = 0.71 g
Molar mass of copper = 63.5 g/mol
Putting i the values, we get:
Thus the number of moles of copper in 0.71 g of copper is 0.011 moles.
