Here's my pick at this:
Entropy (or some form of disorder) will always increase in time.
Thus if you look at snapshots of a system and see that it's entropy is increasing you can tell the flow (or arrow) of time!
Search '2nd Law of thermodynamics' for more info! :)

Answer : The specific heat capacity of the alloy
Explanation :
In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.
where,
= specific heat of alloy = ?
= specific heat of water =
= mass of alloy = 21.6 g
= mass of water = 50.0 g
= final temperature of system =
= initial temperature of alloy =
= initial temperature of water =
Now put all the given values in the above formula, we get
Therefore, the specific heat capacity of the alloy
