chamas
"Chamas" means "flames" in English.
Here, 'chamas' refers to the flames, a plural noun used to describe the visible part of the fire.
As chamas do fogo eram intensas.
The flames of the fire were intense.
In this instance, 'chamas' is the conjugated verb form of 'chamar' in the second person singular (informal 'tu') present tense.
Tu me chamas para conversar sempre.
You call me to talk often.
Here, 'chamas' again means 'flames', used metaphorically to describe intense passion or emotion.
