How does a vase on a table overcome gravity? What would happen if you moved the vase off the table
NeTakaya

Answer:

A vase on a table overcomes gravity because of the upwards force of the table against it, which is stronger than the force of gravity. If you were to move the vase off the table it would no longer have anything stopping gravity from breaking it.

How much heat is required to vaporize 25g of water at 100*c
ElenaW [278]

Answer:

Heat required = 13,325 calories or 55.75 KJ.

Explanation:

To convert a water to steam at 100 degree celsius to vapor, we have to give latent heat of vaporization to water

Which equals ,

Q = mL,

Where, m is the mass of water present

           L = specific latent heat of vaporization

Here , m= 25 gram

L equals to 533 calories (or 2230 Joules)

So, Q = 25×533 = 13,325 Calories

Or , Q = 55,750 Joules = 55.75 KJ

so, Heat required = 13,325 calories or 55.75 KJ.
