question 1
(Unirg-TO) Brazil is admittedly a country of contrasts. Among them, we can point out the temperature variation in Brazilian capitals. Palmas, for example, reached, on July 1, 1998, a temperature of 13 ºC and, on September 19, 2013, a temperature of 42 ºC (with a thermal sensation of 50 ºC). On the Kelvin scale, the variation in temperature in the capital of Tocantins, between the two records made, corresponds to:
a) 13K
b) 29K
c) 42K
d) 50K
question 2
(Udesc) Burning 1,000 g of cooking gas provides 6000 cal. The mass of gas that must be burned to raise the temperature of half a liter of water from 25.00 ºC to 100.0 ºC, and still produce the evaporation of 100.0 ml of water, is:
a) 15.24 g
b) 15.23 g
c) 15.25 g
d) 15.22 g
e) 15.21 g

Human physiology in Enem goes far beyond knowledge about systems and their functioning and anatomy. Yes, anatomy: how to understand the function of a system without knowing the characteristics of the organs that compose it? Human physiology is always charged in a broad way, establishing relationships between various systems and addressing, mainly, how these systems act to keep the body in balance.
