What is the downward push of the atmosphere called?
Atmospheric Pressure
What is the constant movement of water between the atmosphere and earths surface called?
water cycle
What does barometric pressure have to do with evaporation?
Above the surface of liquid water is a layer of water vapor. It has pressure. The atmosphere also has pressure. It pushes against the water vapor. The water vapor pushes against the atmosphere. It is called vapor pressure. It is related to temperature. When the vapor pressure equals barometric pressure, water boils. Normally this occurs at 100C or 212F. If you reduce the barometric pressure, you can reduce the boiling point of water. So when the barometric pressure is lower, the water vapor above the water has an easier time mixing with the atmosphere. As it mixes with the atmosphere, it is replaced by vapor from the water. It evaporates.
Torricelli invented a device for measuring air pressure called a(n)?
To measure the local pressure of the Earth's atmosphere, Torricelli invented the first Mercury Barometer.
What is the wetness of the atmosphere is called?
It is called the humidity of the atmosphere.
The constant pressure in the walls of the arteries is called?
Diastolic pressure
What is The pressure exerted by the gas in earths atmosphere called?
autmospheric pressure
What is the downward push of the atmosphere called?
Atmospheric Pressure
The lines of constant pressure shown on the surface pressure diagram are called?
Line of constant pressure shown on the surface pressure diagram are called isobars. Isobars show areas of high pressure and areas of low pressure. The surface pressure diagram can be used to predict weather patterns.
What factors that are held constant throughout an experiment are called?
Controlled parameters
How are fluid preassure related to the motion of a fluid?
There is a theory called Bernoulli's Theorem which states that: p+dv2/2 +dgh=constant, where p stands for pressure d for density of the fluid g the acceleration due to gravity h the height of th liquid from the base level and v the speed of the liquid. If the pressure throughout the liquid remains constant then the velocity also remains constant. On changing the pressure the velocity also changes to keep the equation value constant.
What is the constant movement of water between the atmosphere and earths surface called?
water cycle
What is a device used to display atmosphere pressure is?
The device is called a barometer.
Variables that remain unchanged throughout an experiment are called?
Independent and Dependent Variables
What is isobaric process?
The process in which change in volume and temperature takes place at a constant pressure is called an isobaric process
What is the physical significance of vander walls constants a and b?
a and b are called vander Wall's and they are used for determination of pressure of real gas they are also used for determination of critical constant of gases
Why dual combustion cycle is called as limited pressure cycle?
In dual combustion cycle heat is added at constant volume which increases the efficiency of cycle, whereas heat addition at constant pressure limits the maximum pressure of the cycle.
