Rosa lives in New York City, which has an average altitude of 33 feet. When she is at home, it takes her 10 minutes to cook noodles in boiling water. She decides to go on a camping trip to Mount McKinley. Her
campsite is located 11,000 feet above sea level. Write the answer to each.
A) Where will the atmospheric pressure be higher: at her home or her campsite?

B) Where will the boiling point be higher?

C) Will the noodles cook faster, slower, or at the same rate at her campsite than home?

Home

Home

Slower

Explanation:

A liquid starts changing its phase to gas when the two pressures become the same i.e., vapor and atmospheric.

At a higher altitude the atmospheric pressure lowers so little amount of heat is required for the vapor pressure of water to equalize with the atmospheric pressure at a higher altitude.

The pressure at the Rosa's home will be higher and lower in the campsite.

The boiling point will be higher at her home.

As the boiling point is lower in the campsite the water used in cooking noodles will evaporate faster this may lead to the noodles being under cooked. The water may evaporate before the noodles have cooked. So, the noodles will cook at a slower rate at the campsite and faster in her home.

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"
