A liquid battery (like older automobile batterys) contain acids which produce hygrogen gas that is explosive.
pour petrol in it and drop a lighted match in it
This is a chemical process (combustion).
Depending on the power of the lighting system; 1 joule (J) = 2,777 778.10-7 kWh.
First the wick is lighted; after this the wax is melted, vaporized and burned.
yes, old and new battery should have same voltage rating. Battery type shud match only capacity may be large.
repetition of similar consonant sounds at the ends of accented syllables, as in blue spurt of a lighted match.
The heat from the lighted match caused the liquid in the test tube to heat up. If the liquid was flammable, it may have caught on fire. However, if the liquid was not flammable, it would have simply heated up and there may have been no other visible changes.
Usually the battery brand does not matter. As long as the replacement battery is an exact match (shape, configuration, voltage, amperage, etc.) it should work.
Temperature is the most important factor affecting the reaction rate in this scenario. By increasing the temperature with the lighted match, the kinetic energy of the particles is increased, leading to more collisions and a faster reaction between the match and the candle wick.
It depends on what is inside the test tube. If the test tube is empty nothing will happen, if there is petrol in the test tube the petrol will ignite.
It is not recommended to recharge a 3V battery with a 12V charger as this may damage the battery. The voltage of the charger should match the voltage of the battery to avoid overcharging and potential safety hazards. It is best to use a charger specifically designed for the 3V battery.
NO, voltage of the charger must match the battery voltage.
