#1 Posted 8:05pm 17-03-10 colligative1. The depression in freezing point caused by a 1M NaCl solution is 0.0123°C. What will be the depression in freezing point caused by 1M glucose solution? 2. When HgI2 is mixed with aqueous solution of KI then freezing point ................. .(increases/decreases/remains same) 3. (True/False) When a liquid and its vapours are at equilibrium and the pressure is suddenly decreased cooling occurs. [ courtesy TAPAS [hide]posted in favor of avinav's request[/hide]]
In every loss, in every lie, in every truth that you'd deny
And each regret and each goodbye was a mistake too great to hide
And your voice was all I heard that I get what I deserve

But there is suffering in life, and there are defeats. No one can avoid them. But it's better to lose some of the battles in the struggles for your dreams than to be defeated without ever knowing what you're fighting for.

#5 Posted 11:06pm 17-03-10 Re: colligativeI think last one is true. Bcoz when u suddenly decrease the pressure, most of the liquid will evaporate - the internal energy of the remaining liquid supplies the enrgy reqd for the process - so cooling should occur. [12] |

SUCCESS IS NOT FINAL..FAILURE IS NOT FATAL...ITS THE COURAGE TO CONTINUE THAT COUNTS .... |
