If a 0.5kg of Pu at 90 degree c is submerged in 2kg of water at 20 degree C inside a bomb calorimeter, what would be the final temperature of the system. C for Pu is 0.133j/g C

C for water is 4186 j/g C

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.

what is the question here. i think you messed up.

answer; 4 electrons;
