Terin likes hot tea and Rylee likes cold tea. Spill the tea on why Rylee should steep her tea in hot water first and then add ice if she wants to drink it right away?
The particles of tea will not mix with cold water
The tea will be diluted when she adds ice
Terin should steep her tea in cold water instead!
The particles of water move faster when it's hot and will mix the tea flavors faster
The movement that makes a dust particle float is called
Bronzian Action
Brownian Motion
Bowel Movement
Dust Mobility
