Ateacher wants to demonstrate that unheated water can boil at room temperature in a beaker within a bell jar connected to a vac-uum pump. however, the vacuum pump is faulty and can reduce pressures only to 15 kpa. can the teacher use this pump to perform the demonstra-tion successfully? explain your answer.

No .

Explanation:

The vapor pressure of water at room temperature is .0313 atom  or 3.13 kPa.

To make a liquid boil, its vapor pressure must be  equal to pressure around it.

So pump must create pressure of 3.13 k Pa or less to make water attain its stage of boiling at room temperature. As the motor  can not produce pressure lesser than 15 k Pa , pump will not be able to make water boil at room temperature.

i'm thinking more like energy
