refractory metals have high melting points and are used in extremely hot environments; if expansion coefficient is lower this prevents high stresses that can develop due to thermal gradients during the high heat up. It helps to have high thermal conductivity as well
Molybdenum
Balancing a chemical equation can often require a whole-number coefficient placed in front of a chemical formula. This upholds the Law of Conservation of Matter, which says that matter cannot be created or destroyed. These coefficients must be in the lowest possible ratio.

Mercury, apparently Bismuth has the lowest thermal condctivity of metals that are solid at room temperature.
It can never be exactly zero, but it is close to 0.
Diamond-like Carbon has a coefficient of friction of as low as 0.05 on polished steel.
Yes.

Ice, like other solids will expand with heat. It has a coefficient of expansion of 50 ppm/°C. So, the colder the ice is, the smaller, and higher density it will be. The warmer, the lower the density, with the maximum temperature (and lowest density) being at the melting/freezing point.
The lowest head loss is from a venturi since it has the lowest coefficient of discharge. typical coefficients range from 0.95-0.99 where the higher coefficient is directly proportional to larger square root of Reynolds number.
