What is the FREEZING POINT of matter in CENTIGRADE?

What is the FREEZING point of matter in FAHRENHEIT?

What do you call the changing from LIQUID to SOLID?

• FREEZING or SOLIDIFICATION

• MELTING or FUSION

What do you call the change from SOLID to LIQUID?

• FREEZING or SOLIDIFICATION

• MELTING or FUSION

The MELTING POINT of a SOLID is the temperature at which it turns to LIQUID. The MELTING POINT of ICE is the SAME as the FREEZING POINT of WATER 0^oC (32^oF).

• True

• False

The change from LIQUID to GAS is called ___. The particles in the LIQUID gain enough HEAT ENERGY to turn into GAS.

• Evaporation

• Condensation

• Sublimation

Everyday, water from rivers, lakes, oceans, and other bodies of water absorbs HEAT and turns into WATER VAPOR. What do you call this process?

• Evaporation

• Condensation

• Sublimation

On a hot day, your sweat on your skin turns into water vapor. What do you call this process?

• Evaporation

• Condensation

• Sublimation

When a GAS is COOLED it gives off HEAT and its particles slow down and change back to LIQUID.

• Evaporation

• Condensation

• Sublimation

A glass with ice becomes moist on the outside. This is because the water vapor in the air condensed on the cold surface of the jar and became wet. What do you call this process?

• Evaporation

• Condensation

• Sublimation
