The temperature of an object is how cold or hot it is.
The final temperature is 12.3 degrees Celsius
<h3>How to determine the final temperature </h3>The given parameters are:
--- the heat of vaporization
--- the specific heat of Aluminum
--- the mass of alcohol
-- the molecular mass of alcohol
Start by calculating the moles of alcohol using:
So, we have:
Next, calculate the amount of heat absorbed by the alcohol using:
The mass of alcohol is 73 grams. So, we have:
Evaluate the products
Divide both sides by -65.92
Express as degrees Celsius
Also, we have:
--- the difference in the initial and the final temperatures.
This gives
Collect like terms
Hence, the final temperature is 12.3 degrees Celsius
