Most often, to see how the metal reacts with when heated with Oxygen.
When submersed in Water, the immediate surface of the metal will not exceed much more than 100degrees Celsius, so no reaction with oxygen is visible.
In air, the temperature can reach highs of nearly 800degrees Celsius, so reactions with oxygen are more apparent.
Several metals can react with water.
some water vapor released from boiling would condense on the cold spoon as water droplets.
Simply: Heat (a flame works nicely) Water (preferably not already boiling) A container (a metal pan will work) A thermometer(grab the meat thermometer, but don't let mom catch you boiling it)
A cup of boiling water since it has higher temperature. Note that heat transfer depends more on the temperature.
'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.
The specific heat of water when it comes to a boiling point is 100 degrees Celcius, or 212 degrees Fahrenheit. The boiling temperature can vary based on the vapor pressure of the atmosphere.
If the metal's temperature has equilibriated with the water, than the temperature of the system (water and metal) will be the same.
Boiling a pot of water on the stove. The heat couldn't reach the water if it were not conducted through the metal pot.
Heat will flow from the boiling water into the ice cube.
The heat will flow from the boiling water to the block of ice.
When water reaches its boiling point, it undergoes a phase change from liquid to vapor. At this point, any additional heat applied to the water will not raise its temperature further, but rather increase the rate of vaporization. Therefore, applying more heat on boiling water is a waste of energy as it will not significantly affect the temperature or any other properties of the water.
Boiling water has a lower latent heat than steam. Steam is the transition from liquid to gas for boiling water. If by boiling water you mean liquid water at the temperature of 100 degrees Celsius then yes, steam has a higher latent heat.
Yes, the boiling water has more heat than the match flame.
A cup of boiling water since it has higher temperature. Note that heat transfer depends more on the temperature.
The metal one - it is the best conductor of heat
