Comparison of internal energies: hot nail versus beaker of water

[memeningful]

Homework Statement

[/B]
A nail is heated in a bunsen burner flame and is about to be dropped into a beaker of water at room temperature.

a) Which of the two substances (nail or water) would you expect to initially have:

i) the highest internal energy
ii) the highest average kinetic energy

Homework Equations

The Attempt at a Solution

for my answer
i) the highest internal energy (to me, it was nail)
ii) the highest average kinetic energy (to me, it was water)

I checked the answers, my logic is wrong, so I have decided to come here to ask why and the reasonsThanks everyone!

i) I think nail .
iii) <W>~T because temperature of nail is higher than water.

 

[CWatters]

Have a think about the factors that effect the internal energy. It's not just the temperature.

I think the factors that effect the internal energy are the temperature and the degrees of freedoms. Metal has 6 degrees of freedom. I don't know about the liquid.

 

[CWatters]

The energy required to heat something up depends on three things. The Temperature change is one.

Would it make a difference if it was an ocean of water?
What would make a difference if the mass and temperature of the two objects were was the same?
