Question

The normal boiling point of an element or a substance is the temperature at which the vapor pressure and the atmosphere are equal, when the atmospheric pressure is defined as 1 atmosphere.

TRUE

FALSE

Answer 2

The boiling point of a substance is the temperature at which the vapor pressure of the liquid equals the pressure surrounding the liquid[1][2] and the liquid changes into a vapor.

The normal boiling point (also called the atmospheric boiling point or the atmospheric pressure boiling point) of a liquid is the special case in which the vapor pressure of the liquid equals the defined atmospheric pressure at sea level, 1 atmosphere.[3][4]

Answer 3

What do you think based on this info?

Answer 4

is it true?

Answer 5

Yep :-)

Answer 6

k thanks. can you answer another one?

Answer 7

I can try.

Answer 8

At which of the following places would water boil at the highest temperature?

At home (1.01 atmospheres)

Camping in Washington state (0.80 atmospheres)

Camping out at the lake (0.98 atmospheres)

Cannot determine from the information given

Answer 9

I think its at home. is that right?

Answer 10

The boiling point corresponds to the temperature at which the vapor pressure of the liquid equals the surrounding environmental pressure. Thus, the boiling point is dependent on the pressure. Boiling points may be published with respect to the NIST, USA standard pressure of 101.325 kPa (or 1 atm), or the IUPAC standard pressure of 100.000 kPa. At higher elevations, where the atmospheric pressure is much lower, the boiling point is also lower. The boiling point increases with increased pressure up to the critical point, where the gas and liquid properties become identical. The boiling point cannot be increased beyond the critical point. Likewise, the boiling point decreases with decreasing pressure until the triple point is reached. The boiling point cannot be reduced below the triple point.

Answer 11

Yep
