Jane: Hi, Nga. Is that a coal-burning stove?
Nga: Hi. Yes, my dad bought it last week. It heats up our home very quickly. Let me put in some more coal.
Jane: . You're too close and will burn yourself!
Nga: . I'm very careful.
Jane: Yes, it feels very warm, but burning coal produces soot.
Nga: Oh no, I didn't know that. . I'll tell my dad.
