A25.0g tin sample was placed in boiling water at 99.5 c until it had the same temperature. afterwards, the tin sample was placed in room temperature water. if the tin sample lost 399.4j of heat and its final temperature was 24.5 c, what is the specific heat of tin?

Answer : The specific heat of tin is, 0.213 J/g.K

Explanation :

Formula used :

where,

q = amount of heat lost = -399.4 J

c = specific heat capacity of tin = ?

m = mass of tin = 25.0 g

= final temperature =

= initial temperature =

Now put all the given values in the above formula, we get:

Therefore, the specific heat of tin is, 0.213 J/g.K

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.
