<u>Answer:</u> The correct statement is low temperature only, because entropy decreases during freezing.
<u>Explanation:</u>
The relationship between Gibb's free energy, enthalpy, entropy and temperature is given by the equation:
Where,
= change in Gibb's free energy
= change in enthalpy
T = temperature
= change in entropy
It is given that freezing of methane is taking place, which means that entropy is decreasing and is becoming negative. It is also given that the reaction is an exothermic reaction, this means that the is also negative.
For a reaction to be spontaneous, must be negative.
From above equations, it is visible that will be negative only when the temperature will be low.
Hence, the correct statement is low temperature only, because entropy decreases during freezing.
Answer:
Option (A) : Positive
Explanation:
A combustion reaction will always be associated with a change in entropy that is Positive due to the gaseous products released. Hence, there is a large positive entropy change.

Explanation:
En 1945, durante la Segunda Guerra Mundial, dos ciudades japonesas; Hiroshima y Nagasaki fueron bombardeadas con bombas atómicas durante el ataque ofensivo.
Hiroshima fue bombardeada el 6 de agosto de 1945 mientras que Nagasaki fue bombardeada el 9 de agosto de 1945.
Las bombas provocaron la muerte instantánea de aproximadamente 120.000 personas y obligaron al emperador japonés a rendirse incondicionalmente.
Breaker measures a large amount and graduated cylinder measures a small amount
This temperature is equivalent to 98.6 degrees Fahrenheit
