Answer:
ΔTb = 0.66 C
Explanation:
Given
Mass of KBr = 185 g
Mass of water = 1.2 kg
Kb = 0.51 C/m
Explanation:
The change in boiling point (ΔTb) is given by the product of molality (m) of the solution and the boiling point constant (Kb)
[tex]\Delta T_{b}= 0.51 C/m * 1.296 m = 0.66 C[\tex]
Explanation:
From the attached phase diagram, one can easily make out the phase in which water exists. Matter generally exists in three physical states which are solid, liquid and gas. Water is a unique compound that can exists in these three states at a given temperature and pressure.
From the attached phase diagram,
- point O is the triple point where the three phases of pure substance co-exists.
- The areas between the curves points at a single phase of matter. Y is a water vapor.
- The lines on the curve denotes two equilibrium phases. For example; X is a phase contain ice and melt water.
