Experiment to show the presence of atmosphere on Mars.
Take a syringe and put its end into a beaker containing water.Now, pull the plunger then,water rises in the syringe due to difference in the pressure of air inside and outside the syringe.When we pull the plunger, the pressure inside the syringe decreases while atmospheric pressure remains same. Thus, water rising in the syringe proves the pressure of the atmosphere exerted on the surface of the water.
