Question

Question 10 (10 points) Which of the following processes would be nonspontaneous? Water freezing at 0 °C. O A helium balloon rising into the air. The combustion of gasoline. A tomato plant returning to a seed.

Answer 1

we can define a process as a spontaneous or non- sponteneous. Sponteneous process are those which occurs smoothly and is owling without belp of any external factor and non-sponteneous process are those which does not occur Smoothly and for it 4G is positive Non sponteneous process occurs in hе темел$e mаnnел. The freezing point . At oo there is a of water is 0°c. equilibrium exists

between water and ice. 50, at 0°c . normally water starts to freeze at ice so water freezing at 0°C is a sponte nevus processing stone The belium balloon is always rising in the air. It is also a sponteneous process. As helium has less weight Than air, so it we add He gas inside a balloon, it always starts Mising inside the air The gasoline is a combustible substance. It is mostly use as a fuel for engines, and is made of boilling petroleum. It is an hydro- -Carbon compound. When gasolin burns it produces water coz and a huge amount of energy. As burning of any hydrocarbon is sponte neous, so combustion of gasolin is also sponte- -neous.

But a tomato plant can't return to a seed again. It is clearly non-sponteneous. A tomato plant generates from a toma to seed. But once seed start to flourish it never goes back to it's original state, so it is . non sponteneous! So; option 4 would be non- sponteneous. dobil
