According to Merriam-Webster’s dictionary, the word hiss is identified as a verb. It means “to make a small sibilant sound”. On page 361, it states,” Impatient, so impatient, so like the water that’s hissing and tumbling in the pot, demanding immediate attention.” The author Tahira used this word to emphasize how impatient Kasim was being at the moment, comparing him to the sounds in the surroundings.
