<human>:  What is the difference between a kettle and a teapot?
<bot>: The main difference between a kettle and a teapot is that a kettle is used to boil water, while a teapot is used to brew and serve tea. A kettle typically has a lid that can be opened, while a teapot has a spout for pouring and often a lid to keep the tea inside warm. Kettles typically have a handle for easy carrying, and teapots typically have a handle for easy pouring.
