yes delta s is positive, delta h is negative making delta g negative at all temps

Is ice melting a spontaneous reaction?
Before we go into the details of whether melting of ice at a room temperature of 25 degree Celsius is spontaneous reaction or not, we first define the spontaneous and non-spontaneous reactions. Spontaneous Reaction, as you know, is a reaction that takes place on its own without an external force or other reaction to drive it e.g. rusting or iron nail, burning of wood etc. Non-Spontaneous Reaction is a reaction which cannot occur without the input of work from an external source. Such as charging of battery, as the electrons flow is required to charge it completely. Now replying to your question: First of all I think, though I am not sure, that heat doesn't transfer from ice to the room. Actually, heat transfers from room to the ice and that's how ice is caused to turn into liquid. The ice needs heat from the surrounding to have its molecules to jiggle (vibrate) and this shaking of ice molecules changes it into liquid. Remember, this reaction is physical, not chemical. From all I have studied and I know, I truly believe that the conversion of ice into liquid form is spontaneous reaction.
How can you prepare ethanol from acetylene?
Full combustion of methane yields only carbon dioxide and water. However, acetylene is one of the products of the partial oxidation (i.e. incomplete combustion) of methane. According to [1], "Acetylene may be produced from methane in any process which raises the methane to a high temperature for a very short period followed by rapid cooling. [....] The process was studied at temperatures of 1000°C to 1300°C and reaction times of .01 to .03 seconds." Source: [1] http://circle.ubc.ca/handle/2429/41033
What matter were studied only for its value?
Gold and Copper have been studied only for its high value.
How are the processes of condensation and vaporization related?
Evaporation and CondensationEvaporation and condensation are the same process going in different directions: evaporation is the process of a liquid turning into a gas, and condensation is the process of a gas turning into a liquid. The term evaporation refers to the process when it is unforced: evaporation occurs well below the boiling point, as can be seen in daily life. These processes are studied as a part of the larger field of thermodynamics. Each substance will have its own energies of condensation and evaporation, due to the size and bond structure of the molecules.
What is endothermy?
endothermic.designating or pertaining to animals, as mammals and birds, whose blood ranges in temperatures from about 98° to 112°F (37° to 44°C) and remains relatively constant, irrespective of the temperature of the surrounding medium; homoiothermal.

What is cryobiology?
Cryobiology is the branch of biology that deals with the properties of organisms and tissues at low temperatures. Temperatures studied may range from moderately hypothermic conditions to cryogenic ones.
