Mars has an average atmospheric pressure of 0.007 would it be easier or harder to drink from a straw on mars than on earth explain

It would be easier to drink from the straw on mars. When we drink using a straw, we withdraw air which reduces the pressure on the liquid inside. If only .007 ATM is exerted on the liquid in the glass, then it will take only a tiny reduction in the pressure inside the liquid to make the liquid rise.

Amethod of procedure that has characterized natural science since the 17th century, consisting in systematic observation, measurement, and experiment, and the formulation, testing, and modification of hypotheses.
