Answer:
B. 111 J
Explanation:
The change in internal energy is the sum of the heat absorbed and the work done on the system:
ΔU = Q + W
At constant pressure, work is:
W = P ΔV
Given:
P = 0.5 atm = 50662.5 Pa
ΔV = 4 L − 2L = 2 L = 0.002 m³
Plugging in:
W = (50662.5 Pa) (0.002 m³)
W = 101.325 J
Therefore:
ΔU = 10 J + 101.325 J
ΔU = 111.325 J
Rounded to three significant figures, the change in internal energy is 111 J.
It is a reaction between an element and a compound that results in a different element and compound
Okay I did the math and I'm guessing around 18*C
Answer:
Temperature gets cooler and precipitation increases.
Explanation:
As average temperatures at the Earth's surface rise, more evaporation occurs, which, in turn, increases overall precipitation. … In addition, higher temperatures lead to more evaporation, so increased precipitation will not necessarily increase the amount of water available for drinking, irrigation, and industry
Higher elevations cause temperatures to drop because the higher up in the atmosphere you go, the colder it gets due to air pressure, in turn causing precipitation to freeze, creating snow. Lower elevations are a lot warmer because the air pressure is not as pressurized causing the temperature to be warmer
