Question

Graphite is better lubricant on the moon than on earth.

$for$ $True$ $=$ $1$ or $false$ $=$ $0$

Answer 1

Answer 0

Graphite is a "solid lubricant," and it is a solid that is slippery. Graphite needs humidity from the air to be slippery. Basically there is no moisture in the air for graphite to work very well. So, the Moon would not have an atmosphere and no moisture to allow the graphite to act as a lubricant. On the moon, there is lack of gravity on the motion of machines.
