Answer: Option (A) is the correct answer.

Explanation:

It is known that in gases, molecules are held by weak Vander waal forces. As a result, they move far apart from each other and attain high kinetic energy.

This causes more number of collisions between the molecules of a gas.

On the other hand, in a solid substance molecules are much more closer to each other because of strong intermolecular forces of attraction. This causes the solids to have least kinetic energy and definite shape and volume.

Hence, we can conclude that the statement molecules in a gas move faster than in a solid, best explains why water vapor has more energy than a block of ice.

16.25 g of water at 54 C relaeases 402.7 J. What will be its final temp?

leonid [27]

Data:
Q = 402.7 J → releases → Q = - 402.7 J
m = 16.25 g
T initial = 54 ºC
adopting: c = 4.184J/g/°C
ΔT (T final - T initial) = ?

Solving:

Q = m*c*ΔT
-402.7 = 16.25*4.184*ΔT
-402.7 = 67.99*ΔT
$\Delta\:T = \frac{-402.7}{67.99}$
$\boxed{\Delta\:T \approx -5.92\:^0C}$

If: ΔT (T final - T initial) = ?
$-5.92^0 = T_{final} - 54^0$
$T_{final} = 54^0 - 5.92^0$
$\boxed{\boxed{T_{final} = 48.08\:^0C}}\end{array}}\qquad\quad\checkmark$
