The pressure of diver = atmospheric pressure + water pressure
atmospheric pressure = 750 mmHg (as given) = 750 / 760 atm = 0.987 atm
Water pressure is
P = hρg
where
h = height of water = 38 ft
1 ft = 0.3048
38 ft = 11.58 m
ρ = density = 1000 Kg / m³
g = gravitational constant = 9.81 m/s2
P = 11.58 X 1000 X 9.81 = 113599.8 Kg / m s^2 Or N /m^2
1 N / m^2 = 1 pa = 9.869 X 10^-6 atm
P = 113599.8 Pa = 1.12 atm
Total pressure = 1.12 + 0.987 atm = 2.107 atm = 2.1 atm (two significant figures)
Answer:
Cesium and Neon
Explanation:
Remember, Neon is a noble gas, also called an inert gas. It does not react really to form compounds. Although chlorine is only one column to the left of neon, it is very reactive and ready forms a salt when combine with sodium. The other elements have similar reactivities to each other. Only Neon is a non-reactive choice.
thermal conduction and convection processes we explain the temperature profile: warmer at the bottom and colder at the top
Temperature is a measure of the internal energy of molecules.
When the pot is on the burner, the lower part of the pot acquires energy from the flame, this energy increases the temperature of the metal that is in contact with the liquid from the bottom, by a process of thermal conduction, while the liquid in the top is kept at the same temperature.
As time progresses, the hotter lower liquid, for which it has a lower with the metal bottom heats up by conduction. density, conscientiously rise and a transfer of heat is created by convection, which raises the temperature of the hot liquid and makes the liquid fall that is colder from the upper part than at the coming into contact
This cycle is repeated heating all the liquid. But the liquid with the liquid in the lower part always at a higher temperature than the liquid in the upper part, the process stops when the liquid in the lower part reaches the boiling point, than the passage from liquid to gas, during which the temperature remains constant.
With the thermal conduction and convection processes we explain the temperature profile: warmer at the bottom and colder at the top.
