Changes of State - Zuzanna R.

Changes of state are when one state of matter transitions to another state. This transition could be either through heat entering, or coming out of the substance.

Endothermic - Zuzanna R.

When something is endothermic, it has heat coming into it. It will usually melt, and change to another state of matter.

Melting - Zuzanna Ratajczak

2018zuzanna00 — 2016-01-29 19:53:56 UTC

Melting occurs when you add heat to a solid substance. That is when the solid will transition to the liquid state.

Melting Point - Zuzanna R.

2018zuzanna00 — 2016-01-29 19:54:02 UTC

The melting point of a substance is its temperature, when it is fully melted. Not all substances have the same melting point.

Evaporation - Zuzanna R.

2018zuzanna00 — 2016-01-29 19:54:09 UTC

Evaporation is the process, where heat is added to a liquid. The liquid then turns into a gas, like for example, into water vapor.

Boiling - Zuzanna Ratajczak

2018zuzanna00 — 2016-01-29 19:54:22 UTC

Boiling is when a liquid is heated up, to the point where it turns into gas. When a liquid is boiling, bubbles of gas will float to the top.

Boiling Point - Zuzanna R.

2018zuzanna00 — 2016-01-29 19:54:30 UTC

The boiling point of a substance is it's temperature, when it boils. Again, not all substances have the same boiling point.

Sublimation- Zuzanna R.

2018zuzanna00 — 2016-02-01 19:41:23 UTC

Sublimation is when a solid will transition to the gas state. When something sublimes, it will never turn into a liquid.
