Total questions: 21
Worksheet time: 11mins
What is the unit of density?
Grams per litre (g/L)
Newtons (N)
Kilograms per metre cubed (kg/m³)
Pascals (Pa)
How is density calculated?
Density = Force / Area
Density = Mass x Volume
Density = Mass / Volume
Density = Volume / Mass
What is the first step to find the density of a liquid?
Tare the balance
Calculate the density using the formula
Measure the mass of the measuring cylinder
Measure the volume of the liquid
What is parallax error?
Error in measuring mass
Error in reading volume due to angle
Error in calculating density
Error in measuring pressure
How do you find the volume of an irregularly shaped solid?
Use a ruler to measure dimensions
Weigh it on a balance
Immerse it in water and measure displaced volume
Use a mathematical formula
What is pressure defined as?
Mass per unit volume
Volume per unit area
Force per unit area
Weight per unit volume
What happens to pressure as depth increases in a fluid?
It fluctuates
It increases
It remains constant
It decreases
What is the formula for pressure in a fluid?
p = m/V
p = A/F
p = F/A
p = ρgh
What does the pressure at a point in a gas or liquid at rest do?
Acts in one direction
Acts equally in all directions
Acts only upwards
Acts only downwards
What is the effect of gravitational field strength on pressure?
It only affects solids
It has no effect
It increases pressure
It decreases pressure
What is the relationship between density and pressure in a fluid?
Pressure is independent of density
Higher density leads to higher pressure
Density has no effect on pressure
Higher density leads to lower pressure
What is the effect of area on pressure when lying on a bed of nails?
Pressure decreases with area
Pressure increases with area
Pressure remains the same
Area has no effect on pressure
What is the correct formula for calculating density?
Density = Force / Area
Density = Mass / Volume
Density = Volume / Force
Density = Mass x Volume
What is the primary cause of pressure in a fluid?
Weight of the fluid
Shape of the container
Movement of particles
Temperature of the fluid
What happens to the weight of the fluid above a point as depth increases?
It decreases
It increases
It fluctuates
It remains constant
How does temperature affect the density of a fluid?
Density increases with temperature
Density decreases with temperature
Temperature has no effect on density
Density fluctuates with temperature
What is the relationship between pressure and volume in a gas?
Pressure increases as volume increases
Pressure decreases as volume increases
Pressure is independent of volume
Pressure and volume are directly proportional
What happens to the pressure in a fluid when the fluid is heated?
Pressure decreases
Pressure increases
Pressure remains constant
Pressure fluctuates
How does the viscosity of a fluid change with temperature?
Viscosity increases with temperature
Viscosity decreases with temperature
Viscosity remains constant with temperature
Viscosity fluctuates with temperature
What is the relationship between pressure and temperature in a gas?
Pressure increases as temperature decreases
Pressure decreases as temperature increases
Pressure is independent of temperature
Pressure increases as temperature increases
What happens to the buoyant force on an object as it is submerged deeper in a fluid?
It increases
It decreases
It remains constant
It fluctuates
