Vedclass · Answer

(B) The bulb emits thermal radiation. The black-painted surface on the $X$ side is a better absorber of radiation compared to the white/shiny surface on the $Y$ side.As the black surface absorbs more heat,the air inside the $X$ bulb expands more due to the increase in temperature.This increased pressure pushes the alcohol level down on the $X$ side and up on the $Y$ side.Therefore,the level of alcohol on the $X$ side decreases.

When the bulb is switched on,what happens to the level of alcohol on the $X$ side?
