?? Why Ice floats on Water ?

? We know Density = Mass/Volume

?⭕️ Remember the rule ? Substance with low density will float on substance of high density. ?

? When We freeze the Water to Ice it's Volume increases.

? As volume is at denominator in above formula density of ice is less than Water of same Volume.

? Due to this Ice floats on Water tho it's made of water.

? Trick to Remember ? The bottom of Bislery bottle is bulged out when we keep it in Deep freezer; due to increase in volume of ice. ?

?? What is Light Year (प्रकाशवर्ष) ?

?Light year is a distance travelled by light in a year.

?It is used to measure distance between two Planets in space.

? Light Year contains year in it's name but it is not a unit of Time (like second, month, year.)

? ⭕️ Remember? Light Year is a Unit of Distance & not of Time. ? ⭕️

?? interestingly if a planet is at 3 light years from earth then we will require 3 years to reach at that planet if we travel at the speed of light.?
