    Undergrad Mass-Light Conversion: How Much is Lost?

    I understand what u mean but some mass is lost , u c the light (from flame) is emited .. its not a reflection , its a energy. So it has to be something . Light can't be created (conflicts law) so only thing possible thing is HEAT TO LIGHT or MASS TO LIGHT .

    Do we lose weight by respiration ? (Losing carbons)

    We take in Oxygen (O2) & give Carbon dioxide (CO2) . Say a guy somehow does not digest any food or fat for 5 min .. So will lose weight equal to all the "C" lost from his body in that 5 min ??
