Answer:
False. Temperature is independent of volume
[ Answer ]
It would be very confusing and date and calculations would be off and inaccurate
[ Explanation ]
If scientists didn't use the SI system, then all the calculations and data they would send to each other would be mixed up and confusing. If Americans used one metric system and The Chinese used another metric system, converting the data would be inaccurate and take way to much time. Everyone would have their own idea for what is right, and no one would have a clue what other people meant.

Answer:
The excess charge has distributed itself evenly over the outside surface of the sphere.
Explanation:
Since the hollow sphere is a conductor, it has free electrons that can move about within the sphere. In this light, an excess charge, the like charges repels each other, therefore ensuring that charges are spread as far apart as possible. There is therefore an evenly distributed charge on the outside surface of the sphere.
Answer:
entire wall temperature difference = 29.29 K
Explanation:
given data
temperature difference steel ΔT = 17.79 K
steel L = 1.471 cm
lead L = 2.416 cm
to find out
temperature difference across wall
solution
we know that here heat transfer by steel and lead are same
and
heat transfer = k×A×ΔT / L ................1
so
H( lead) = H (steel)
k×A×ΔT / L = k×A×ΔT / L .................2
here we know
k for steel = 14.4 W/mK
k for lead = 36.6 W/mK
so put here all value in equation 2
k×ΔT / L = k×ΔT / L
36.6×ΔT / 2.416 = 14.4×17.79 / 1.471
ΔT = 11.50 K
so
entire wall temperature difference = 11.50 + 17.79
entire wall temperature difference = 29.29 K
