Explanation:
It is mainly the very low density of gases that make them bad conductors of heat. In liquids and solids atoms and molecules are densely packed and transfer of energy has much smaller distances to happen.

Answer:
The cube of gold will have the greatest mass.
Explanation:
All the cubes have the same size, so they have the same volume.
The property that varies among the cubes is density.
D = m/V Multiply both sides by V and transpose.
m = DV
Since V is a constant, m ∝ D.
That is, the cube with the greatest density will have the greatest mass.
The observed densities are
Iron = 7.9 g/cm³
Brass = 8.5 g/cm³
Lead = 11.4 g/cm³
Gold = 19.3 g/cm³
Gold has the greatest density, so the cube of gold has the greatest mass.
Answer:
8000000 litres
Explanation:
General formula,
→ 1 megaliter = 1000000 litres
Then 8 megaliters will be,
→ 8 × 1000000
→ [ 8000000 litres ]
Hence, the solution is 8000000 L.
