Chapter 1.1 Flashcards
(20 cards)
Tell the the volume, density, shape and fluidity of solid?
Has a fixed volume, high, has a definite shape, does not flow
Tell the the volume, density, shape and fluidity of liquid?
Has a fixed volume, moderate to high, no no definite shape - take the shape of the container, generally flow easily
Tell the the volume, density, shape and fluidity of gas?
No fixed volume - expand to fill the container, low, no definite shape - text the shape of the container, flow easily.
Which process have a fixed temperature?
Boiling
How is the temperature and pressure connected to state of matter?
Change the temperature and pressure can change state of matter.
Is temperature in volume directly proportional or indirectly proportional ?
When the temperature increase, volume increases
What is the term meant by melting point?
Temperature at which solid turns to liquid
What’s the term of freezing Point?
Temperature at which liquid turns to solid
What is meant by the term boiling point?
Temperature at which liquid turns into gas.
Is melting point and freezing point temperature the same?
Melting Point and freezing point temperature are the same
What is mean by the term atom?
Atom is the smallest particle that cannot be broken down by any chemical reaction.
What is meant by the term molecule?
Molecule is a particle of two or more atoms join together.
What is meant by the terms ions?
Ion is an atom or a group of atoms that carries an electrical charge.
Is melting/boiling/evaporation endothermic reaction or exothermic reaction. Explain.
Melting or boiling or evaporation temperature increase ,energy-absorbed, endothermic reaction
Is freezing/condensation exothermic, or endothermic reaction?
Temperature decreases, energy released, exothermic reaction
Particle theory that concern with temperature
As temperature increases, particle move far apart.
As temperature decreases, particle move closer.
Compressing gas about the particle theory of it
The molecule got closer together and hit the wall of the container more often.
The higher the pressure, the closer particle to each other.
Heating gases and write the particle theory of it
Gas particles gain more kinetic energy, hit the wall of the container with increased the force.
Will pressure increase with the increase speed of gas particle?
Pressure will increase because the more often the particles collide with the walls, the greater the pressure.
What is the relation between temperature and average speed of gas particles?
As temperature increases, average speed of the gas particle increases
