Which setLiquids, gases and plasmas are all classified as fluids. Which behaviour under a sideways force earns them thaTwo fluids are poured from identical jars and one flows far more sluggishly than the other. Which named quantiGases can be squeezed into a much smaller volume than liquids or solids can. What is the reason for this?Water poured from a narrow bottle into a wide bowl takes on a new outline. Which description matches a liquid?Density compares two measurable properties of a sample of matter. Which statement defines it?Density is mass per unit volume. Which unit is therefore the SI unit of density?The kilogram was originally fixed by reference to a definite volume of one substance. Which mass was chosen?Gold is about 2.5 times as dense as iron, and iron is about 2.5 times as dense as aluminium. Roughly how many A reservoir has a surface area of 50.0 km^2 and an average depth of 40.0 m. Taking the density of water as 1.0Solids and liquids have roughly comparable densities, while gases are far less dense than either. What accountA ton of feathers and a ton of bricks are set side by side. Which statement about the two piles is correct?Pressure is defined from a force and the surface on which that force acts. Which definition is correct?The SI unit of pressure is the pascal. One pascal is equal to which of these?An astronaut works where the outside pressure is essentially zero, and the gauge on her air tank reads 6.90 x A static fluid presses on the inside wall of its container. In which direction does the force produced by thatPressure in a fluid and the force that pressure produces differ in one important respect. Which statement is cTwo non-SI pressure units are still in everyday use. Which pairing of unit and application matches usual practFor a fluid of average density rho, the pressure caused by the fluid's own weight at a depth h below its surfaA dam holds back water that is 80.0 m deep at the wall, so the average depth of the water in contact with the Water 80.0 m deep presses on a vertical dam wall 500 m wide, and the average pressure on that wall is 3.92 x 1Two lakes hold water to the same average depth at their dams, but one lake stretches ten times further back frWhat is the standard value of atmospheric pressure at sea level?The atmosphere effectively ends at an altitude of 120 km and produces a pressure of 1.01 x 10^5 Pa at the grouHow deep must a diver go in fresh water before the pressure due to the water's weight alone equals 1.00 atm, tA swimmer floats 10.3 m below the surface of a pool that is open to the air, and 10.3 m of water alone produceA diver feels a clear pressure change after descending only a metre in a pool, while a lift ride of many storeThe relation P = h rho g was derived for a fluid in a container, yet it is applied to open water and to the atPascal's principle describes what happens when the pressure on an enclosed fluid is changed. What does it statBlaise Pascal was kept from studying mathematics until he was 15, yet he made lasting contributions in severalIn a hydraulic system two pistons sit at the same height and friction is negligible. A force of 500 N acts on A hydraulic system has two pistons at the same vertical height and negligible friction. Which relation connectA hydraulic system can multiply an applied force many times over, yet it cannot multiply the work done. What pGauge pressure is quoted relative to a chosen reference. Which reference does a pressure gauge use?How is absolute pressure obtained from a gauge reading?A tyre gauge reads 34 psi where atmospheric pressure is 14.7 psi. What is the absolute pressure inside the tyrFluids push rather than pull, so in most cases absolute pressure cannot fall below zero. What is the smallest An open-tube manometer is a U-shaped tube with one arm open to the air and a liquid inside. The liquid levels A mercury barometer is a tube of mercury with a nearly pure vacuum sealed above the column. What does it measuWith every heartbeat the arterial blood pressure swings between a maximum and a minimum. What are those two vaMercury rather than water is used in the manometer for arterial blood pressure. Mercury is 13.6 times denser tAn intravenous drip must just enter a vein where the blood pressure is 18 mm Hg above atmospheric. The fluid hWhat is a buoyant force?Why does an object immersed in a fluid feel a net upward force at all?Archimedes' principle links the buoyant force to something the object does to the fluid around it. What does iTwo blocks of equal volume are held fully submerged in water, one made of aluminium and one of lead. How do thA block of solid steel of mass 1.00 x 10^7 kg is fully submerged in water. Steel has a density of 7.8 x 10^3 kThe same 1.00 x 10^7 kg of steel is reshaped into a hull that can displace 1.00 x 10^5 m^3 of water. Taking waWhether an object floats or sinks in a fluid is settled by a single comparison. Which comparison is it?Ice has a density of 917 kg/m^3 and fresh water 1000 kg/m^3.

What are those forces Surface tension makes the surface of a liquid behave like a stretched elastic sheet. What produces it?An iron sewing needle laid flat can rest on a water surface even though iron is denser than water. Which stateA soap bubble of radius 2.00 x 10^-4 m is blown from soapy water whose surface tension is 0.0370 N/m. The gaugA tall narrow glass tube is stood upright in a dish of mercury, and mercury makes a contact angle of 140 degreSap has a density of 1050 kg/m^3, a contact angle of zero and the surface tension of water at 20.0 degrees CelIntraocular pressure keeps the eye in shape. What is its normal range?A force of 3.00 N is enough to rupture an eardrum of area 1.00 x 10^-4 m^2.
