Cambios de Fase

revisar las fases de la materia y los cambios de fase

QuestionAnswer
sólido las moléculas vibran en su lugar
líquido las moléculas se mueven unas alrededor de otras lentamente
gas las moleculas se alejan unas de otras
sólido mantiene su forma; no toma la forma de su contenedor
líquido fluye; toma la forma de su recipiente
gas no tiene forma visible; llena su contenedor
materia cualquier cosa que tenga masa y ocupe espacio
fase una forma o estado notablemente diferente de la misma sustancia
macroescala grande y fácilmente visto
escala molecular demasiado pequeño para ver sin herramientas
libertad de movimiento la forma en que las moléculas de una sustancia se mueven entre sí
derretimiento sólido convirtiéndose en líquido
congelación líquido que se vuelve sólido
evaporación líquido convirtiéndose en gas.
condensación gas convirtiéndose en líquido
Si AGREGAS energía cinética... las moléculas se mueven más rápido y la temperatura aumenta (provoca fusión y evaporación)
Si QUITAS energía cinética... las moléculas se mueven más lentamente y la temperatura baja (provoca congelación y condensación)

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
