Chapter 7 Part 2 (KPT :3) Heating & Cooling Curve Flashcards
REFER TO NOTES GRRRRRRRRRRR
what happens to the solid particles when heated? (heating curve)
when heated, the particles of the solid gain kinetic energy and vibrate more vigorously about their fixed positions
what happens to the solid particles at melting point? (heating curve) (solid + liquid)
at melting point, the heat supplied is taken in by the particles to overcome the forces of attraction that hold them in their fixed positions
what happens to the movement of particles at the liquid and solid state? (heating curve)
the particles change form vibrating about their fixed positions in a solid to sliding past each other throughout the liquid
when happens to the arrangement of particles at liquid & solid state? (heating curve)
they will change from being very closely packed in a regular arrangement in a solid to closely packed in an irregular arrangement in a liquid
what happens to the forces of attraction between the particles in the liquid and solid state? (heating curve)
the forces of attraction between particles change from being very strong to strong
what happens to the liquid particles as it continues to be heated? (heating curve)
as the liquid continues to be heated, the particles gain kinetic energy and move at greater speeds
what happens to the particles at boiling point? (liquid and gas) (heating curve)
at boiling point, the heat supplied is taken in by the particles to overcome the forces of attraction between the particles holding them in the liquid state
what happens to the arrangement of the particles in the liquid + gas state? (heating curve)
the particles change from closely-packed in an irregular arrangement in a liquid to being spaced very far apart and irregularly arranged in a gas
what happens to the movement of particles in the liquid + gas state? (heating curve)
the particles change from sliding past each other throughout the liquid to moving randomly and freely at great speeds in all directions
what happens to the forces of attraction between the particles? (liquid & gas) (heating curve)
the forces of attraction between particles change from being strong to weak
what happens to the particles as the gas continues to be heated? (gas) (heating curve)
as the gas continues to be heated, the particles gain kinetic energy and move at even greater speeds.
what happens to the particles when cooled? (gas) (cooling curve)
when cooled, the particles of the gas lose kinetic energy and move at even lower speeds.
what happens to the particles during condensation? (gas + liquid) (cooling curve)
during condensation, heat is released to strengthen the forces of attraction between particles, causing them to be held in the liquid state.
what happens to the arrangement of the particles? ( gas + liquid) (cooling curve)
the particles change from being spaced very far apart and irregularly arranged in a gas to closely packed in an irregular arrangement in a liquid
what happens to the movement of particles? (gas & liquid) (cooling curve)
the particles change form moving randomly and freely at great speeds in all directions in a gas to sliding past each other throughout the liquid.
