Right at the surface of the ocean, the pressure is just the same as the air pressure at sea level; that is, one "atmosphere", or about 14.7 PSI (Pounds per Square Inch).
But water pressure increases with increasing depth: For each foot of depth, the water pressure increases by 0.445 PSI.
SCUBA divers, who need to be very aware their depth because of this pressure effect, often use this rule: Every 33 feet of depth, water pressure increases by one "atmosphere" (14.7 PSI). So, for example, at 66 feet the pressure on a diver is three atmospheres: There's one atmosphere of pressure from the air, and two atmospheres from the water.
the difference between thermal conductance and thermal conductivity is that:
thermal conductivity(k) and its unit is (W/m.K)it is coefficient of heat transfer through materials in contact with air (the out side layers).
thermal conductance(C) its unit is (W/m2.K)it is coefficient of heat transfer through materials at the middle or surrounding by anther materials(the middle layers).
Heat is the form of energy due to molecular motion. When energy is added to an object its molecules move faster and heat is generated.
By increasing its speed, or velocity.
force =mass x acceleration
therefore mass = force /acceleration
and acceleration = force/mass
The Law of conservation of mass-energy indicates that the mass-energy of the universe is constantly changing to maintain the mass-energy constant.
friction and gravity
To determine the heat of vaporization you must first determine the amount of heat the substance gave off to water by multiplying the mass of water by the change in temperature and the specific heat capacity of water. You need to divide this number by the number of moles of the unknown substance.
For example, when heat energy (thermal energy) is added to a substance, either its temperature will increase, or it will change its state (as when ice is melted).
Actually, when we say force exerted it is the what we called tension. Tension is the opposite type of compression. But it doesnt mean it redirects the word "force exerted" but the term magnitude of the pulling force exerted by an object.
this often happens on strings,cable,chain etc.
This would be its system of equilibrium:
A system is in equilibrium when the sum of all forces is zero.
Yes it is.
Heat is form of energy and can be transferred through 3 mode
Conduction Convection and Radiation
The mechanical advantage is 5.
Mechanical Advantage = Output Force/Input Force
Through conduction, convection, and radiation.
A lever pivots on its fulcrum.
79F = 26.1C
No, it's a thermal insulator.
potential energy is stored energy and kinetic energy is being used.
So it is kinetic.
F = kx
where F = force, k = spring constant or spring stiffness, x = elongation
116 kilometers per hour (kph) is 72.1 miles per hour.
A complex machine.
When the temperature of the two objects is equal, the Thermal Flow will stop.
Convection, conduction, and radiation are all methods of heat transfer.
