use as anti freeze for automobile
ethyl glycol
when ice melt its volume
decrese
if temp increase then ability to hold vapour woul
incrwease
if salt is added in water then its boiling and freezing
boling increase and freezing decrease
boiling point water at high altitude
at high altitude boiling pint decreawse

boiling point in high tmp
high
water is heated from 0 to 10 then its volume
first decrease and then increase

increase in temp on sound waves
it wil increse sound speed
