Built-in air conditioner
Why do dogs stick their tongues out?
Tamilamirthan , Chennai, Tamil Nadu
View AnswerSometimes, when dogs are hot, there is increased blood flow to the tongue, and the blood vessels in the tongue swell. As the dog pants, moisture is created by their breath which evaporates and cools the tongue. As the tongue cools down, the blood flow is cooled and this goes through the dog’s entire body, cooling them down fully. Thus, when dogs stick their tongues out, it becomes a kind of internal air conditioner for them.

In winter, how come it does not rain, but instead snows?
Adithyan , Palakkad
View AnswerMost precipitation starts out as snow high in the atmosphere, where the air is extremely cold. However, in summer, as the snow falls down to the earth, the air closer to the earth is hot. So, the snow falls down as water, or rain. However, in winter, since the air near the earth in some places is very cold too, the precipitation does not change form and falls as snow. Hence, rain or snow will depend on the temperature.

Bubbles galore
How does soap make bubbles?
Manya.R.I. , Bengaluru
View AnswerThe molecules in soap have two different ends, one that attracts water and one that repels it. When soap mixes with water, the opposite ends of the soap molecules hold between themselves a thin bit of water, with a tiny bit of air. In other words, a bubble. So that's how bubbles are formed when soap mixes with water.

Funny voice
How does Helium change our voice?
Tamilamirthan , Chennai
View AnswerThe air we breathe is made up of mainly nitrogen and oxygen. Helium is less dense than regular air. Hence, sound travels faster through helium than through regular air. When we inhale helium, it surrounds our vocal cords. When we speak after inhaling it, the sound quality of our voice changes because our voice travels faster across our vocal cords. Hence, the voice tone sounds higher since the sound is moving faster.
