Why did you heat the metal in a dry test tube rather than in the boiling water?

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.

What will happen when you put a metal spoon in boiling water?
some water vapor released from boiling would condense on the cold spoon as water droplets.
What lab equipment is used to hold 50mL of boiling water?
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)
Which can transfer more heat a cup of boiling water or 1 basin of tap water?
A cup of boiling water since it has higher temperature. Note that heat transfer depends more on the temperature.
What is the specific heat of water when it comes to a boiling point?
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.
Why does a metal spoon get hot in a pot of boiling water?
'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.
If you heat a metal in boiling water how do you know the metals heat?
If the metal's temperature has equilibriated with the water, than the temperature of the system (water and metal) will be the same.
What is an example of transfer of heat through conduction?
Boiling a pot of water on the stove. The heat couldn't reach the water if it were not conducted through the metal pot.
How will heat flow if an ice cube is dropped in boiling water?
Heat will flow from the boiling water into the ice cube.
What will be the flow of heat when you drop a block of ice in boiling water?
The heat will flow from the boiling water to the block of ice.
Why is it a waste of energy to apply more heat on water that is already boiling?
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.
Does steam has highest latent heat than boiling 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.
Does boiling water have more heat than a match flame?
Yes, the boiling water has more heat than the match flame.
Which can transfer more heat a cup of boiling water or a cup of tap water?
A cup of boiling water since it has higher temperature. Note that heat transfer depends more on the temperature.
Four spoons wooden metal rubber and plastic were placed in boiling water with candle wax on them which one did the candle wax melt from first?
The metal one - it is the best conductor of heat

What type of heat is boiling water?
convection
What purifies water?
boiling it to intence heat
