Mount Everest rises to a height of 8,850 m above sea level. At a base camp on the mountain the atmospheric pressure is measured

Mamont248 [21]

Answer:

74.86°C

Explanation:

P₂ = Vapour pressure of water at sea level = 760 mmHg

P₁ = Pressure at base camp = 296 mmHg

T₂ = Temperature of water = 373 K

ΔH°vap for H2O = 40.7 kJ/mol = 40700 J/mol

R = Gas constant = 8.314 J/mol K

From Claussius Clapeyron equation

$ln\frac{P_2}{P_1}=\frac{\Delta H}{R}\left(\frac{1}{T_1}-\frac{1}{T_2}\right)\\\Rightarrow ln\frac{760}{296}=\frac{40700}{8.314}\left(\frac{1}{T_1}-\frac{1}{373}\right)\\\Rightarrow ln\frac{760}{296}\times \frac{8.314}{40700}+\frac{1}{373}=\frac{1}{T_1}\\\Rightarrow 0.0028735=\frac{1}{T_1}\\\Rightarrow T_1=347.996\ K$

T₁ = 347.996 K = 74.86°C

∴Water will boil at 74.86°C

James is trying to prove Newton's 2nd law of motion. He tries to move four different objects with different masses, shapes, and

STatiana [176]

The car is the heaviest object there and mass is proportional to force, meaning the heavier it is the bigger the force should be in order to move it.

A 50.0 kg student climbs 5.00m up a rope at a constant speed. If the student's power output is 200.0 W, how long does it take th

hammer [34]

Answer:

The time taken by the student to climb is 12.25 seconds and work done is 2450 J.

Explanation:

Given that,

Mass of the student, m = 50 kg

The student climbs to a height of 5 meters at a constant speed.

The student's power output is 200.0 W, P = 200 W

The power of an object is given by work done divided by time taken. So,

$P=\dfrac{W}{t}$

(b) W is work done,

$W=mgh\\\\W=50\times 9.8\times 5\\\\W=2450\ J$

(b)

$t=\dfrac{W}{P}\\\\t=\dfrac{2450}{200}\\\\t=12.25\ s$

So, the time taken by the student to climb is 12.25 seconds and work done is 2450 J.
