8. Why do we see water droplets on the outer surface of a glass containing ice cold water? 9. Convert the following temperature to the CELCIUS scale (a) 25K (b) 373K.

10. How will you show that air has maximum compressibility?
​

8. We see water droplets on the outer surface of a glass containing ice cold water because condensation is happening! This happens when warm water vapour from the surroundings come into contact with a cool surface (in this case the cool glass) and loses heat and condenses, forming water droplets on the surface of the glass.

9 a) -248.15 celcius

b) 99.85 celcius

10. by using 2 syringes, one filled with water and one filled with air. when you compress it, you will find that the one with water barely compresses and the one filled with air should be able to be compressed quite a bit. and to the extent that the syringe is unable to be pushed down further, that is the maximum compressibility of air.
