A teacher 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.

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.

5. How are humans affecting global climate change?
andreyandreev [35.5K]

Answer:

Due to the generation of carbon dioxide

Explanation:

Climate change occurs due to global warming generated by greenhouse gases. Carbon dioxide is the gas that does not leave or allow solar radiation from the sun to rise from the Earth's surface, increasing the average temperature of the planet.

Burning fossil fuels for energy generation such as coal is another source of carbon dioxide generation. The generation of energy should be directed towards the production of renewable energies, using sources such as solar and wind energy.
