How does atmospheric pressure affect the boiling point of a liquid

Physics

Darya [45]3 years ago

3 0

Answer:

The atmospheric pressure and boiling point are directly proportional

Increasing atmospheric pressure increases the boiling point also

Explanation:

The atmosphere contain molecules that are in constant motion. They exert a downward force on a liquid’s surface. The higher the air pressure, the harder it is for the liquid to evaporate. Therefore, the boiling point of a solvent or liquid is affected by the atmospheric pressure and boiling point is raised.

A liquid in a high pressure environment boils at a higher temperature.

When placed in a lower pressure environment it boils at a lower temperature.

If Ms. Ramirez drops a watermelon from the top of the second-floor fire escape outside her room, and it takes 1.5 seconds to hit

mamaluj [8]

The velocity of the watermelon as it hits the ground is 14.715 m/s.

Given the data in the question;

Since the Watermelon was dropped from rest,

Initial velocity of the Watermelon; $u = 0m/s$

Time taken for the Watermelon to hit the ground; $t = 1.5s$

We know that, Acceleration due to gravity; $g = 9.81 m/s^2$

Now, we determine the velocity of the watermelon as it hits the ground which is the final velocity.

From the First Equation of Motion:

$v = u + at$

Now, under gravity, acceleration ''a" will Acceleration due to gravity; $g = 9.81m/s^2$ , "v" is the final velocity, "u" is the initial velocity and "t" is the time taken.

So, we substitute our values into the equation

$v = 0m/s\ +\ ( 9.81m/s^2\ * 1.5s )\\\\v = ( 9.81m/s^2\ * 1.5s )\\\\v = 14.715 m/s$

Therefore, the velocity of the watermelon as it hits the ground is 14.715 m/s

Calculer l intensité du courant qui le traverse

MissTica

Answer:

Le calcul du courant se fait avec deux éléments : la tension et la valeur de la résistance. Courant (A) = tension (V) / résistance (Ohm) ce qui donne la formule I = U/R.
