Answer:
<h2>
ΔE = -1,382,800Joules</h2>
Explanation:
The internal energy of the system according to the thermodynamics law is the difference between the heat released by the system and work done to the system. Mathematically;
ΔE = q - W where;
ΔE is the change in internal energy of the syatem
q is the heat released by the system
W is the work done to the system
Given W = 4.50×10² kcal and q = 5.00×10² kJ
Since 1cal = 4.184Joules
4.50×10² kcal = (4.50×10²×10³)×4.184
W = 4.50×10² kcal = 1,882,800 Joules
q = 5.00×10² kJ = 5.00×10⁵Joules
q = 500,000Joules
Since ΔE = q - W
ΔE = 500,000 J - 1,882,800 J
ΔE = -1,382,800Joules
Hence, the change in the internal energy of the system is -1,382,800Joules
I believe it's Mercury, because the only other option would be Pluto and it's not even considered a planet anymore
Hope this helps
Answer:
Explanation:
Given the following :
Temperature (Th) of hot reservoir = 30°C (30 +273) = 303K
Temperature (Tc) of cold reservoir = 0°C (273K)
Quantity (Q) of heat transferred from hot reservoir = 400 J
Total change in entropy (ΔStotal) :
ΔStotal = ΔShot + ΔScold
ΔS = Q/T
Hot reservoir is losing 400J of heat ;
Q = - 400 J
ΔShot = Q/Th
ΔShot = - 400/303
ΔShot = - 1.32 J/K
ΔScold = Q/T
ΔScold = 400 / 273
ΔScold = 1.47 J/K
ΔStotal = ΔShot + ΔScold
ΔStotal = - 1.32 + 1.47
ΔS total = 0.15 J/K
A tornado is a natural force It is a very strong wind that causes thing to damage
Work is force times distance
pressure is force over area
hence pressure times volume will give us force times distance aka work
1.1 atm is 111.458 kPa
si units
111.458 kPa times 2.3 L equals 256.35 J
