Matter on the Move
What happens to the movement of the particles of liquid as it is heated
the movement of particles speeds up
what is the solvent in a cup of tea
the hot water is the solvent in this scenario
What is a unit of measurement for distance?
Centimetres or Meters.
what is the formula for density
density= mass / volume
what is buoyancy
the tendency to rise and float in a fluid
How do particles move around in a solid?
The particles will vibrate in place.
What is a homogeneus substance and give examples.
Similar to solutions its when you cant see the different particles in a substance. Ex) Coca-cola,Tea,Coffee
In A liquid if the temperature increases.Does the flow rate increase or decrease?
The Flow Rate Increases
Does water have a greater flow rate than maple syrup?
Yes it does, the water will flow faster than maple syrup.
What is Archimedes Principle?
The buoyant force is equal to the weight of the displace water.
what is the particle model of matter
All matter is particles
particles are moving
spaces between particles forces between particles
Define the following terms: Saturated Solution,unsaturated solution and supersaturated solution
A saturated solution is when no more solute can dissolve in the substance while an unsaturated solution is the opposite .When something is unsaturated it means more can be dissolve.A saturated solution is the point where no more solute can dissolve.
If the Density in a gas increases.Would the viscosity decrease or increase?
The Viscosity Will Increase.
Ia a balloon has a density of 0.00035 will it sink in mercury?
No it will sink because the mercury has a higher density.
What is the buoyant force?
The force is measured in newtons,and it is the force against the force of gravity.(its the force that allows things to float)
What force needs to take place to change a solid to a gas.
Sublimation needs to take place
What is a element and give a example.
a element is its own particles and cant be broken.
Ex. Gold, Hydrogen, Helium, etc.
if you heat up honey will the flow rate increase or decrease
The viscosity will increase
If mercury has a density of 13.55g/mL,Nitrogen of 0.00125g/mL and Vegetable oil of 0.9g/mL. What order would you expect to find them(from top to bottom) if placed in a test tube?
Nitrogen,Vegetable oil,Mercury
how does and object volume affect buoyancy
the more compact the object is the less likely it is to sink and the more spread out the object is the more likely to float
What is the particle model of matter
- Particles are always in movement
- all substances are made of particles
- Particles have spaces between them
- There are attractive forces among particles
What is the difference between a substance that is soluble in water and substance that is insoluble in water and give examples?
When something is soluble it means it can dissolve while if it insoluble it can dissolve such as oil.
what is the flow rate of a substance that travels 35 centimetres in 10 seconds
It moves 3.5 cm/s(centimetres per second)
a wooden block has a mass of 14.2 grams and a volume of 20cm3 what is the density of the wood?
density= mass/volume
= 14.2g/20cm3
= 0.71g/ml
When dose floating occur?
When the buoyant force is greater then the gravitional force.
