DO YOU KNOW WHAT TOPIC WE WANT TO LEARN TODAY?

HMMI THINK I KNOW. BUT, IM NOT SURE

Understanding Specific Latent Heat

Change of Phase

Water exists in three phases: Solid(ice) Liquid Gaseous(steam)

What happen to the temperature when ice melts????

Temperature remains the same

When a solid melts or a liquid is boiling, heat is absorbed but the temperature remains constant. There are four main changes of phase: Melting Boiling Condensation Solidification

The four main changes of phase are summarized in figure below

The common characteristics of the four process in the change of phase are: iii.A substance undergoes a change of phase at particular temperature. iv.Heat energy is transferred during phase of change v.During change of phase, the temperature remains constant even though there is transfer of heat
