Answer:

Q = 80000 cal

Step-by-step explanation:

La expresin para el calor es

Q = m
c_(e)ce ΔT

el calor especifico del agua es ce= 1 cal/gr ºC

la temperatura de ebullición del agua es Ef = 100ºC y partimos de la temperatura ambiente To= 20 OC

Q = m 1 ( 100 – 20)

q= 80 m

en el ejercicio no se da la masa de agua, pro podemos suponer, pote lleva 1 litros = 100 G

Q = 80 1000

Q = 80000 cal
