Answer from: avelyp

Liquid a has a lower boiling point than liquid b.

Explanation:

Hello,

In this case, volatility is associated with three factors:

1. Vapor pressure: this is the pressure exerted by the gas molecules in equilibrium with the liquid. The higher the vapor pressure, the higher the volatility.

2. Intermolecular forces: are the interactions attracting or repelling the material's molecules. The stronger the forces, the lower the volatility as the molecules remain strongly closer.

3. Boiling point: is the condition of both temperature and pressure at which a liquid passes from liquid to gas. The lower the boiling point, the higher the volatility as more molecules easily pass from liquid to gas.

In such a way since liquid a is more volatile than liquid b, the answer is liquid a has a lower boiling point than liquid b based on the aforesaid factors.

Best regards.

Answer from: Quest

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.

Answer from: Quest

the formula for the conversion of temperature from degree celsius to kelvin is:

$k = ^{o}c + 273.15$

the sample of water at $38^{o}c$ is converted to kelvin temperature by using the above formula as:

$k = 38^{o}c + 273.15 = 311.15 k$

on comparing the two samples of water at $38^{o}c$ or we can say that at $311.15 k$ and at $295 k$ respectively. the difference between the temperatures of two samples of water is:

$311.15 k - 295 k = 16.15 k$

hence, one can say that the sample of water at $38^{o}c$ is greater than the sample of water at $295 k$ by $16.15 k$ .
