Density & Pressure

Fill in the blanks The density of a substance is defined as the mass per unit volume and is measured in kilograms per metre cubed (kg ).To find the density of a liquid: • Find the mass of the measuring cylinder by placing it on a balance, then fill it with the liquid and measure the new mass. The difference in masses is the mass of the liquid. • The volume can be read from the cylinder. • Find the density using the equation.If the solid is regularly shaped, measure its dimensions using a ruler or other measuring tool and then use a mathematical formula to find the volumePressure is defined as the force per unit area and is measured in PascalsThe pressure at a point in a gas or liquid at rest acts equally in all directions and causes a force at right angles to any surface.The pressure beneath a liquid surface increases with depth, the density of the liquid and the gravitational field strength. • It is given by 𝑝 = 𝜌𝑔ℎ What is the volume (in cm^3) of ice cube of 2g mass and density 0.96 g 2 3 6 Increasing and decreasing pressure choose the right answer Skies decreases pressure Pin increases pressure spikes increases pressure Boats decreases pressure A hydraulic jack is used as a force multiplier.If the force on the small piston of area 5 cm^2 is 7 N. What is the force applied by the big piston on the wheel if its area is 350 cm^2. 0.5 kN 500 kN 5000 kN Write in 4 steps how to calculate density of gas write in 4 clear steps
