Question

a. The density of lead is 11.6 g cm and that of wood is 800 kg m . What do you
understand by these statements?​

Answer 1

Answer:

by these statements we can understand that the mass of 1cm^3 lead is 11.6 gram and mass of 1m^3 wood is 800kg

Answer 2

ρ=ρ
o
​
(1−γdt)
In this case dt = change in temperature = 100
Initial density = 11.34 gm /cc
γ = 3 X 28 X 10
−6

Putting these values we get,
density at 100
0
C as
11.34(1−0.0084)=11.34×0.9916=11.24
