Very cold temperature same

Explanation:

Superconductors perform best at very cold temperatures because resistivity of this kind of materials decays drastically with temperature.Chromium is most likely to be the best conductor of electricity because it belongs to the Transition Metal group of the periodic table.Oxygen is likely to be the best electrical insulator because it belongs to the Non Metal group, and is mostly found in gas state.Water has lower viscosity than any oil at any temperature.Distillation is a separation procedure that uses the difference of boiling points of two mixed liquids, evaporating one of them by heating the mix at an intermediate temperature, right between both boiling points.Since weight is a force it must be measured in newtons.Mass is the measurement of the amount of particles in a body. Since moving a body doesn't change its amount of particles, then the mass will be the same here and there.
