What is an example of torricelli's principle?
An example of Torricelli's principle is when you use a barometer to measure atmospheric pressure. The height of the mercury column in the tube of a barometer is determined by the atmospheric pressure pushing down on the mercury in the dish. This is in accordance with Torricelli's principle, which states that the height of a liquid in a tube is inversely proportional to the pressure acting on it.
What is the force the Sun exerts on the Earth?
The force the Sun exerts on the Earth is known as gravitational force. This force is responsible for keeping the Earth in orbit around the Sun. The magnitude of this force is determined by Newton's law of universal gravitation, which states that the force is directly proportional to the product of the masses of the two objects (in this case, the Sun and the Earth) and inversely proportional to the square of the distance between them.
What is the relationship between temperature, volume, and pressure in a gas system when the pressure variable is manipulated?
When pressure is increased in a gas system, the volume decreases and the temperature increases. This is known as Boyle's Law, which states that pressure and volume are inversely proportional, while Charles's Law states that pressure and temperature are directly proportional.
Who is the principle states the pressure exerted by a moving stream of fluid is less than the pressure of the surrounding fluid?
This is known as Bernoulli's principle, which states that as the speed of a fluid increases, its pressure decreases. It is commonly applied in fluid dynamics to understand the relationship between fluid velocity and pressure.
What scientific rule states that the pressure exerted by a moving stream of fluid is less than the pressure of the surrounding the fluid?
Bernoulli's principle states that the pressure exerted by a moving stream of fluid is less than the pressure of the surrounding fluid. This principle describes the relationship between the speed of a fluid and its pressure, showing that as the speed of a fluid increases, its pressure decreases.
What is the atmospheric pressure on the top of Mt Whitney?
The atmospheric pressure on the top of Mt. Whitney, the highest peak in the contiguous United States, is about 30% lower than at sea level. This means the pressure is significantly reduced due to the higher altitude.
What is an example of torricelli's principle?

The height of the mercury column in the tube of a barometer is determined by the atmospheric pressure pushing down on the mercury in the dish.

What are the contributions of robert boyle in the field of physics?
Boyle made a number of contributions but he's most commonly most remembered for his contribution to the kinetic model of gases with "his" law (which states that the pressure of a gas is inversely proportional to its volume).
What does Dalton's Law of Partial Pressures say?
The total pressure of a gas mixture is the sum of the individual pressures.
What law states that the total pressure of a confined gaseous mixture equals the sum of individual gas pressures?
Daltons law
What is atmospherical pressure at higher and lower altitude?
In general, barometric pressure, or atmospheric pressure, drops as you go up in elevation. For example, at 18,000 ft. above sea level, the average barometric pressure is about half the average pressure at sea level (see the related links for charts) However, barometric pressure also varies widely with the weather (weather charts almost always show the movement of low pressure and high pressure zones), so true barometric pressure cannot simply be calculated, but must be measured. In the United States, the National Oceanic and Atmospheric Administration provides hourly barometric readings for many locations across the country (see related National Weather Service measurement link)
What are the characteristics of partial pressure?
Dalton's law of partial pressures) states that the total pressure exerted by the mixture of non-reactive gases is equal to the sum of the partial pressures of individual gases.
Explain what is meant by the partial pressure of a gas and how it applies to respiration?
Partial pressure of a gas applied to respiration is explained by Dalton's Law. It states that in every mixture of gas, each individual gas has its own pressure that makes up the total pressure of gas.
What is the formula for Dalton's Law?
Dalton's Law of Partial Pressure is : Ptotal = Pgas1 + Pgas2 + Pgas3 + ... It states that when a Gas is made up of a miture of different gases, the total pressure of the mixture is equal to the sum of the partial pressures of the components
What general movement of low pressure centers across the United Stated is from?
The general movement of low pressure centers across the United States is typically from west to east. This is due to the prevailing westerly winds aloft and the overall atmospheric circulation patterns in the region.
Why does the pressure in the lungs become lower than the atmospheric pressure during inhalation afte the contract of the diaphragm?
The contraction of the diaphragm enlarges the volume of the chest cavity. This causes the air pressure in the chest cavity to decrease. This is because of the physics principle that states that, if the amount of gas in a particular container is constant, the product of pressure and volume is constant. Since you're increasing volume, the pressure must decrease.
Why is it easier to cook in a pressure cooker?
The universal gas law states that (pressure * volume/temperature) of a gas is a constant. Hence, if the volume stays the same (as in a pressure cooker), the air in the cooker can increase in temperature beyond the boiling point of water as pressure builds up over the normal atmospheric pressure. A higher temperature means faster cooking. The above is a very simplistic view of the physics involved.
