Answer:
Explanation:
Molar heat capacity at constant volume Cv  of a gas = n x .5 R where n is degree of freedom of the gas molecules 
CO₂ is a linear molecule , so number of degree of freedom =  3 + 2 = 5 
3 is translational and 2 is rotational degree of freedom . There is no vibrational degree of freedom given . 
So Cv = 5 / 2 R 
= 2.5 R . 
 
        
             
        
        
        
Osmosis is the diffusion of water <span>across a semipermeable membrane (usually cell membrane) from a region of low solute concentration to a more concentrated solution so it can reach equilibrium (balance). 
D</span>iffusion is <span>a spontaneous movement of particles from an area of high concentration to an area of low concentration. 
Both results in particles moving and help balance out the concentrations.
Also, in osmosis, the water molecules are moving. In diffusion, it is the solutes moving.
I hope this helps and explains well.</span>
