Physics assignment :: XI 1. A vertical U tube of uniform cross section contains mercury in both of its arms. A glycerine (d = 1.3 g/cm3) column of length 10cm is introduced into one of the arms. Oil of density 0.8g/cm3 is poured in the other arm until the upper surfaces of the oil and glycerine are in the same horizontal level. Find the length of oil column. Density of mercury is 13.6 g/cm3. (9.6cm) 2. Two communicating cylindrical tubes contain mercury. The diameter of one vessel

Boyle’s law states that for a fixed amount a gas at a fixed temperature volume is opposite to its pressure. The air in the marshmallow is what follows Boyle’s law. The marshmallow is similar to a gas because when the pressure in the syringe is decreased the pressure in the marshmallow is increased. The volume increases in the marshmallow. So basically when the plunger is pulled out the pressure in the syringe decreases and the volume of the marshmallow

mole of hydrogen gas has a mass of 2.02 g. Use your value of molar volume to calculate the mass of one Liter of hydrogen gas at STP. The density is in g/L. Compare your value to a literature value? (Consult a hand book or text book) 2. In setting up this experiment‚ a student noticed that a bubble of air leaked into the gas tube when it was inverted in the water bath. What effect would this have on the measured volume of hydrogen gas? Would the calculate value be too high or too low

surface troughs‚ high pressure systems‚ and frontal boundaries. Boyle’s law (sometimes referred to as the Boyle–Mariotte law) states that the absolute pressure and volume of a given mass of confined gas are inversely proportional‚ if the temperature remains unchanged within a closed system.[1][2] Thus‚ it states that the product of pressure and volume is a constant for a given mass of confined gas as long as the temperature is constant. The law was named after chemist and physicist Robert Boyle‚ who published

object‚ M being the mass of the object‚ and V being the volume of the object. Mass is the space an object takes up. It is the amount of matter present in an object. Mass is measured using a triple beam balance. Units used to measure it are grams‚ metric tons ‚ milligrams ‚ and kilograms . Volume is the amount of space enclosed by a shape or object‚ how much 3-dimensional space it occupies. It can be occupied by a solid‚ liquid or gas. The volume can be measured in cubic meters‚ cubic centimeters‚ or
