What is pressure in terms of the individual molecules Like how do the individual molecules interact to create "pressure" in a fluid?

a longitudinal wave moves energy that is to the direction of the wave’s movement. - true

your answer is c! hope this : )

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
