During an experiment, ice and water were placed in a perfectly insulated thermos flask at 0 °C. Describe this system when it phase reaches equilibrium.

Is this science?

sorry I don't know the answer to this question

Explanation: An insulated thermos indicates that there is no heat interactions between system and surroundings and there is a thermodynamic equilibrium between water and ice.

The mechanic equilibrium means that water and ice have the same pressure and thermal equilibrium means that water and ice have the same temperature. Given the existence of phase change, it means that phase with greater specific heat storage a major portion of heat. Water has a specific heat greater than in ice, which according to the First Law of Thermodynamics, there is less water than ice.

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
