Due to atmospheric pressure the weight of 10 kg of cotton is grater than 10 kg of iron.
The answer is two fold: Real and Psychological. The Real part is explained by the relationship between mass and force. When you lift anything up what you feel is the force it exerts on your system (your hand for example) and not the weight. 1kg or iron exerts more unit force on your hand because its mass is concentrated in smaller area. On the other hand, 1kg of feather has its mass distributed over a wider area and therefore exerts a smaller unit force. It therefore genuinely feels lighter. The psychological bit is that we automatically expect something big to weigh more than and item far smaller than it. Of course it won't be if they are the same weight. Your perception therefore is that if "feels" lighter.

The wind is as big as an elephant but lighter than a feather.nice riddle
Yes a feather is lighter than water. Water can be gallons. A feather however is no pounds. If you have a scale at home than fill up a cup of water than get a feather, from like a scarf a pillow etc. And put the water on first, then write down the number. Then put the feather on the scale and write down that number then compare.
