Faahfaahinta casharka

Natiijada casharka

I can describe and explain what happens to very hot water as it cools.

Muuji qoraalka
The higher the temperature of a hot drink, the faster its particles are moving. A hot drink makes the particles in the air around it move more quickly. The particles of a hot drink begin to move less quickly as they transfer energy to the air particles. The greater the temperature difference between a hot drink and the air, the faster it cools down.
