If you lay a steel needle horizontally on water it will float if you place the needle vertically into the water it will sink explain why?
Needle floats if u place it on the surface of the water even its density is heavier than water because there is a thin film on the water surface that is stretched towards the sides of the container because of the collision force of the molecules & this is called suface tension when u plae the needle vertically it tears the film therefore it sinks
Why a pin or clip keep floating on water?
This happens because like us water has a skin and if you place a pin flat on the water and don't disturb the "skin" the pin will float as it is resting on the "skin" of the water, whereas, if you had to attempt to place the pin with the point facing down it will break/pierce the "skin" of the water and sink to the bottom and not rest on top because it experiences buoyancy which is more than its weight

Why is the skin of frog always moist?
Skin is the respiratory organ in frogs. A thin water film is formed on the skin of frog and to retain this thin film of water for long time, mucus is produced by the mucus glands present in the skin. The O2 gets dissolved into this thin film of water from where it gets diffused into the blood capillaries. And this is the reason, why the skin of frog is richly supplied with blood capillaries. If the skin of frog dries up, the frog dies. The frogs also have lungs but 80% of respiration takes place through the skin. So, frogs have two respiratory organs 1) Skin 2) Lungs.
How does tepid sponging reduce body temperature?

How does moist skin help a frog?
Moist skin helps in respiration. A think film of water is formed on the surface of frog, into which the atmospheric O2 gets dissolved and ultimately diffuses into the blood vessels underlying the skin. This is the reason, the skin of frog is richly vascular.
