Phase Changes and heat transfer

Front

What is vaporization?

Back

Vaporization is the phase change from a liquid to a gas, occurring when the particles gain enough energy to overcome intermolecular forces.

Front

What is the direction of heat transfer?

Back

Heat transfers from an area of high temperature to an area of low temperature.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature and density.

Front

What is sublimation?

Back

Sublimation is the phase change from a solid directly to a gas without passing through the liquid phase.

Front

What is recombination?

Back

Recombination is the phase change from plasma to gas, where ions and electrons combine to form neutral atoms.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials, where heat moves from the hotter object to the cooler one.

Front

What is the role of temperature in phase changes?

Back

Temperature affects the energy of particles; as temperature increases, particles move faster, which can lead to phase changes.

Front

What is the difference between melting and freezing?

Back

Melting is the phase change from solid to liquid, while freezing is the phase change from liquid to solid.

Front

What is condensation?

Back

Condensation is the phase change from gas to liquid, occurring when gas particles lose energy and come together.

Front

What is deposition?

Back

Deposition is the phase change from gas directly to solid, bypassing the liquid phase.
