A liquid in glass thermometer uses a liquid volume of which varies with temperature
according to the relationship Vθ=V0(1+aθ+bθ2)
where Vθ and V0 are volumes of the gas at θ 0C
and 0 0C respectively and “a” and “b” are
constants. If a=bx103. What will the reading on
the liquid gas in glass scale when the actual
temperature is 60 0C

gets less

blue light is scattered in different directions by the tiny molecules of air. blue is scattered more than other colours because it has a shorter distance to travel which results in smaller waves. this is why we see a blue sky most of the time.

b. false
