Which of the following is true for a gas under conditions of very low temperature? PV ÷ nRT = 1, because all gases behave ideally at very low temperatures. PV ÷ nRT = 1, because the actual volume of the gas molecules becomes considerable. PV ÷ nRT > 1, because the low temperatures speed up the particles. PV ÷ nRT < 1, because particles are unable to overcome intermolecular attractions.

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.

air

in a tire you fill a tire with air

then a couple days later you check the air pressure in the tire

hope this mark me brainliest
