No, adding more salt to water will increase the density of the water, making the spoon more likely to sink rather than float. The increased density of the saltwater would effectively displace more water, causing the spoon to become more submerged.
some water vapor released from boiling would condense on the cold spoon as water droplets.
Yes, adding salt to water increases its density, which can make some objects that would normally sink, like eggs, float. By altering the density of the water, the buoyant force exerted on the object can be increased to make it float.
'nothing, it's like putting a spoon in a hot soup' Wrong ^ As the metal spoon is a better conductor of heat than the air the hot water (or soup) and the spoon as a larger surface area with the air (or active sight) it transfers heat to the surrounding faster, thus cooling the hot liquid faster.
it will float, with it being a soft metal, try it for yourself
Conduction is what transfers the heat in this process. The fast moving particles in the hot electric coil collide with the slow-moving particles in the cool pot. The transfer of the heat causes the pot's particles to move faster. Then the pot's particles collide with the water's particles, which in turn collide with the particles of the spoon. As the particles move faster, the metal spoon becomes hotter.
because the spoon is more dense than water
When a metal spoon is placed in water, the water exerts an upward buoyant force on the spoon due to the displacement of water. If the force of buoyancy is greater than the weight of the spoon, the spoon may bend due to the imbalance of forces acting on it. This effect is especially noticeable if the spoon is made of a soft or thin metal.
You can't make a bar of metal float on water, but boats with metal hulls float. Also, metal bars and other metal objects float on mercury.
In water, a metal spoon sinks. In water, a plastic spoon floats.
A plastic spoon floats because plastic is less dense than water, so it displaces enough water to generate an upward buoyant force that exceeds its weight, causing it to float. The shape and size of the spoon also contribute to its ability to stay afloat.
The spoon sticking out of a cup of hot water also gets hot because heat is transferred from the water to the metal spoon through conduction. The metal material of the spoon allows heat to flow easily, causing the temperature of the spoon to increase as it comes into contact with the hot water.
Metal conducts heat better than wood, so the metal spoon quickly absorbs the heat from the hot water, making it feel hotter to the touch compared to the wooden spoon, which does not conduct heat as efficiently.
Metal ships are built to float.
Conduction
Yes, if it makes the water denser, the boat will float easier. For example, it is easier to float in salty water.
Cesium metal will float on water as its density is lower than that of water, causing it to float.
Conduction of heat. When the spoon is left in the boiling water, the molecules in the hot water transfer kinetic energy to the metal spoon, causing its temperature to increase.
