Physics A stone floor feels cold to the bare feet but a carpet on the same floor feels warm. This is because The stone conveys the heat away from the feet more rapidly than the carpet The carpet is a better conductor of heat than the stone The floor and carpet are at different temperatures The human body maintains a constant temperature The stone conveys the heat away from the feet more rapidly than the carpet The carpet is a better conductor of heat than the stone The floor and carpet are at different temperatures The human body maintains a constant temperature ANSWER DOWNLOAD EXAMIANS APP
Physics An egg sinks in soft water but floats in a concentrated solution of salt because Albumin dissolves in salt solution and egg becomes lighter The density of salt solution exceeds the density of eggs Egg absorbs salt from the solution and expands Water has high surface tension Albumin dissolves in salt solution and egg becomes lighter The density of salt solution exceeds the density of eggs Egg absorbs salt from the solution and expands Water has high surface tension ANSWER DOWNLOAD EXAMIANS APP
