It is transferred by conduction when two objects at two different temps touch each other, and the one with the most heat will transfer its heat to the cooler object until they both have the same temperature..
At the point of touching the fast moving molecules of the warmer object will collide with the slower moving molecules of the cooler object.

summarize rutherford's model of an atom, and explain how he developed thus model based on the results of his famous gold-foil ex

Ainat [17]

Rutherford's atomic structure model was revolutionary. Contrary to J.J. Thompson's "plum pudding" model (which consisted of a solid, even mixture of protons and electrons), Rutherford's model consisted of one small, positively charged, dense nucleus, a layer of empty space, and a layer of negatively charged electrons. He came to this conclusion through his gold-foil experiment. He shot a ray of alpha particles towards the thin gold foil, and to Rutherford's surprise, some of the rays reflected back instead of going straight through the foil as he originally thought.

Atmospheric pressure at the summit of mount everest is about one third the pressure at sea level, which is 760 mm hg. if oxygen

vichka [17]

Atmospheric pressure at sea level is 760 mmHg.
We have been told that at the summit the pressure is only one third the pressure at sea level.
Then the pressure at the mountain top is $\frac{760}{3}$ mmHg
Air is made of a mixture of gases. the pressure that each gas exerts individually contributes to the total pressure of the system. The pressure that each gas exerts is the partial pressure of that gas which depends on the mole fraction of that gas or percentage composition of the individual gas.
Partial pressure of Oxygen - total pressure x percentage composition
Therefore pO₂ - $\frac{760 * 0.21}{3}$ = 53.2 mmHg
Answer is 53 mmHg
