Fizz it up
Why is carbon dioxide (CO2) added to soft drinks?
Swastika Yadav , New Delhi
Soft drinks have a certain amount of CO2 gas dissolved in them to produce bubbles. This is done by the manufacturers to make the drink fizzy. The gaseous CO2 comes in contact with water and undergoes a chemical reaction that produces carbonic acid. The carbonic acid imparts the acidic flavour to the drink. Without it the soft drink would taste flat.

3-D trivia
What is a three dimensional figure?
Uttam Prajapati , West Champaran, Bihar
A three-dimensional figure is defined in geometry as any shape or object that takes up space. Thus, a solid figure that consists of length, width and height will be three-dimensional. These figures have thickness and depth. All physical things that you can touch are three-dimensional.

Why does our nose bleed at high altitudes?
Rudraksh Bharti , Bhagalpur, Bihar
At high altitudes, humidity (amount of water vapour in the air) reduces, and the air becomes dry. When dry air passes through the nasal cavity, it dries the nasal membranes that line the nose, forming a crust. If pressure is applied to the nose, then, these crusts bleed. The water vapour present in the air acts as a lubricant for the movement of air through our nose, and the absence of it increases friction and irritates our nasal membranes, resulting in bleeding.

Eyes that trick
Why does the moon appear white?
Pugalendhi R , Sathyamangalam, Tamil Nadu
The moon appears white because of the presence of photoreceptors, known as the cone in the retina of our eyes. The moon often appears to be in different colours through the year because of the way it reflects the sun’s light. But, its actual colour is grey. The moon contains magnesium, calcium, iron, aluminium, oxygen, feldspar, silicon, and pyroxene. These are basic minerals and collectively give the moon a grey colour.
