Tina is correct
Explanation:
Tina is correct because LPG stove involves both physical and chemical changes. Gaseous LPG comes out as gas and it is liquified.This is physical change. Liquid LPG burns this is chemical change. Petroleum gas is converted to liquid form under pressure as LPG. The main component of Liquified Petroleum Gas(LPG) is butane, the other being propane and ethane. It is odourless, but the LPG in our domestic gas cyclinders gives a foul smell due to ethyl mercaptan.
