12) Em um experimento, uma substância líquida foi exposta a uma variação de temperatura
durante 8 minutos. Nesse experimento, a temperatura T, em graus Celsius, dessa substância, variou
em função do tempo m, em minutos, de acordo com a relação T(m) = – 5m2
+ 40m, sendo que a maior
temperatura atingida por ela correspondeu ao seu ponto de ebulição.
Qual foi o ponto de ebulição, em graus Celsius, dessa substância nesse experimento?
A) 4 °C.
B) 8 °C.
C) 40 °C.
D) 80 °C.
