If a sealed syringe that contains some gas in heated in which direction will the syringe plunger move

The movement of the plunger will take place in outward direction elevating the volume in the syringe.  

The upsurge in heat will lead to an elevation in temperature of the gas particles. This elevation in temperature will lead to an elevation in motion. The elevation in motion (kinetic energy) will result in an increase in pressure within the syringe. This elevation in pressure will further result in an upsurge in the volume of the syringe.  

According to Charle's law, the temperature and volume are directly equivalent, that is, as the temperature increases the volume will also increase. Thus, an increase in temperature and heat will result in an increase in volume making the plunger to move outward.  

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .
