Question

Nishigandha kept a vessel containing all the ingredients for making tea in a solar cooker. Shivani kept a similar vessel on a stove. Whose tea will be ready first and why?

Answer 1

The tea of stove because the heat energy produced by fuel in stove is more than the heat energy produced due to Sun

Answer 2

The pot with all ingredients of tea kept over a stove will make the tea faster. This is because  it is over direct flame and therefore it will heat up quicker than solar heat.

Water boils at 100 degree centrigrade and over direct flame the pot will easily heat to that limit and the tea will be ready.
