Oxygen is gas at room temperature. remember the air you breath have 21%oxygen and it is gas
Answer : The final temperature of the aluminum and ethylene glycol is
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 aluminum =
= specific heat of ethylene glycol =
= mass of aluminum = 13.60 g
= mass of ethylene glycol = 23.27 g
= final temperature of aluminum and ethylene glycol = ?
= initial temperature of aluminium =
= initial temperature of ethylene glycol =
Now put all the given values in the above formula, we get:
Therefore, the final temperature of the aluminum and ethylene glycol is
