States of Matter Flashcards
What is thermal energy?
The energy carried by heat flow .
what is kinetic energy?
kinetic energy of an object is the energy that it possesses due to its motion.
What is heat?
heat is energy in transfer to or from a thermodynamic system
what is temperature?
a physical quantity that expresses hot and cold
what is melting?
a physical process that results in the phase transition of a substance from a solid to a liquid.
What is boiling?
the rapid vaporization of a liquid
what is evaporation?
a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase.
what is condensation?
the change of the state of matter from the gas phase into the liquid phase, and is the reverse of vaporization.
what is freezing?
a phase transition where a liquid turns into a solid when its temperature is lowered below its freezing point
what solidifying?
to make solid; to change from a liquid or gaseous to a solid form
what is sublimation?
the transition of a substance directly from the solid to the gas state, without passing through the liquid state.
what is deposition?
Reduced pressures tend to reduce unwanted gas-phase reactions
