Question: 1.The minimum ignition energy (MIE) is the minimum energy input required to initiate combustion in a flammable mixture. For flammable gases it is typically 0.1

1.The minimum ignition energy (MIE) is the minimum energy input required to initiate combustion in a flammable mixture. For flammable gases it is typically 0.1 mJ and for dusts it is typically 10 mJ, although substantial variation can be expected with specific materials. The mass of a penny is typically 2.6 gms. How far must this penny be raised to contain potential energy equivalent to 0.1 mJ?
