Which of the following best describes a property of water?
2 answers:
Answer: C. Remaining liquid over a wide temperature range
Explanation: Water has a high specific heat i.e it requires a large amount of heat to raise the temperature of 1 gram of water through . This is because the molecules of water are associated through strong hydrogen bonds.
It is also an universal solvent as it can dissolve most of the substances in it due to its high dielectric constant.
The freezing point of water is , that is liquid water converts to solid form at
and the boiling point of water is
, that is liquid water converts to gaseous form at
. Thus it can remain in liquid form over the temperature range of
to
Water has a high surface tension as the molecules of water are held together by strong hydrogen bonds.

Answer:
The final equilibrium temperature of the system is
For the ice it would melt completely the mass that would remain is Zero
Explanation:
In the following question we are provided with
Mass of the ice = 129 g = 0.129 kg
Mass of the steam = 19 g = 0.019 kg
Initial temperature is = 0°C
Temperature of steam = 100°C
Following the change of state of water in the question
The energy required by ice to change to water is mathematically given as
Where is a constant known as heat of fusion and the value is
The energy been released when the steam changes to water is mathematically given as
Where is a constant known as heat of vaporization and the value is
The energy released when the temperature of water decrease from 100°C to 0°C is
100°C)
Where is the specific heat of water which has a value
Looking at the values we obtained we noticed that ]
What this means is that the ice will melt
bearing in mind the conservation of energy
looking the way at which water at different temperature were mixed according to the question
Heat lossed by the vapor = heat gained by ice
