Boiling Alcohol using a resistor :D
I took a 10W 3.3Ω resistor ,immersed it in alcohol and then powered it up with around a hundred watts . And the results are here for you to see :
The setup of the experiment. I had included an ammeter and a voltmeter to monitor the power delivered to the resistor in real time. I had also included a LM35 temperature sensor to check the temperature of the alcohol. But for some reason (??) , the sensor gave up on me and started showing impossible temperatures like 154.4 degrees (as you can see in the green multimeter).
Bubbles started forming as soon as the power was switched on :
The Alcohol starts boiling vigourously around a minute after the power is switched on. Alcohol vapors can be seen rising from the cup :
I was pretty excited at this point to see the alcohol boiling so vigorously. I was actually tempted to bring a match and try lighting the vapors. Here is a video of the alcohol boiling :
Now that i think about this , this is actually a kinda good idea for boiling alcohol. Since open flames are no where involved , its much safer to heat alcohol in this way than by using a spirit lamp or a gas stove. But then , who wants to heat alcohol ?
I now intend to make a more safer setup and try to ignite the alcohol vapors. It will be rather interesting to see what will happen.
Thats all for now ,
