You can't get something from nothing is practically stating the law. The law means states that energy can't be created or destroyed, in other words, it's constant. So in saying so, you truly can't get something from nothing

Answer:
2993 °C
Explanation:
A reaction is spontaneous if the free Gibbs energy (ΔG) is negative. ΔG is related to the enthalpy of the reaction (ΔH) and the entropy of the reaction (ΔS) through the following expression.
ΔG = ΔH - T . ΔS
For 1 mol, if ΔG < 0, then
ΔH - T . ΔS < 0
ΔH < T . ΔS
-320.1 × 10³ J < T . (-98.00 J/K)
T < 3266 K
To convert Kelvin to Celsius we use the following expression.
K = °C + 273.15
°C = K - 273.15 = 3266 - 273.15 = 2993 °C
Answer:
m<2 = 86
Explanation:
Vertical angles means the angles are equal to each other so:
<1 = <2
17x + 1 = 20x - 14
17x - 20x = -14 - 1
-3x = -15
x = 5
m<2:
20x - 14
20(5) - 14
100 - 14
86
Answer:
this raise the temperature is x = 3
Explanation:
Heat capacity is the relationship between heat and temperature change
C = Q / ΔT
if the heat in the system is given by the change in energy and we carry this differential formulas
= dE / dT
In this problem we are told that the energy of thermal radiation is
E = A V T⁴
Let's look for the specific heat
c_{v} = AV 4 T³
the power to which this raise the temperature is x = 3
