a pan is put on an open flame4 & metal is a thermal conductor ->  a pan is a thermal conductor  a pan is put on an open flame0 & a flame are a part of a fire ->  the flame gives off heat  the flame gives off heat & a pan is put on an open flame1 ->  the flame is a source of heat  the flame is a source of heat & a pan is put on an open flame & a pan is put on an open flame3 ->  the pan is exposed to a source of heat  a pan is a thermal conductor & the pan is exposed to a source of heat & if thermal conductor is exposed to a source of heat then that conductor may become hot / warm ->  the pan will become hot  the pan will become hot & a pan is put on an open flame7 ->  the hot pan is a kind of hot object  the hot pan is a kind of hot object & a hot object is a source of heat ->  the hot pan is a source of heat  the hot pan is a source of heat & a pan is put on an open flame3 & an ice cube is placed in the pan ->  the ice cube in the hot pan is exposed to a source of heat  the ice cube in the hot pan is exposed to a source of heat & a pan is put on an open flame5 & a pan is put on an open flame6 ->  the ice cube in the hot pan will become hot  the ice cube in the hot pan will become hot & a pan is put on an open flame2 & becoming hot means increasing in heat energy -> a pan is a thermal conductor0: the ice cube will melt and change into water in hot the pan  a pan is a thermal conductor0 & the hot pan is a source of heat -> a pan is a thermal conductor1: the water from the melted ice cube in the pan is exposed to a source of heat  a pan is a thermal conductor1 & if a substance is exposed to a source of heat then that substance may become hot / warm -> a pan is a thermal conductor2: the water from the melted ice cube will become hot  a pan is a thermal conductor2 & evaporation means a substance changes from a liquid into a gas by increasing heat energy & becoming hot means increasing in heat energy -> the water from the melted ice cube will then evaporate
