Potassium metal is a metal that explodes when put in cold water. It causes a chemical reaction which results in a large explosion.
choices are: The cold will flow from the metal into the hot water, causing the hot water to warm up and the metal to cool down. b. The energy from the hot water will flow into the cold metal, cooling the water down and heating up the metal. c. The cold will flow from the metal into the hot water, causing the hot water to cool down and the metal to warm up. d. The metal will cool down because the specific heat of water is high.
No, paper will not keep water cold for the longest time. A metal cup will keep water the same temperature for the longest time. I know this because I did a science experiment about this but instead of cold water I used hot, which won't really make a difference. The next would be glass then paper.
Metal is a good conductor of heat, so on a cold day, the metal bench quickly loses heat to the environment, making it feel cold to the touch. Your body also conducts heat to the metal, causing it to feel cold as it draws heat away from your body.
A metal shovel would feel cold to the touch because metal is a good conductor of heat. When the metal comes into contact with your skin, it quickly transfers heat away from your body, making it feel cold.
Because metal conducts heat faster than wood. The temperature of the water will be carried up to your hand much more efficiently by the metal spoon than a wooden spoon.
Caesium
Sodium is a shiny metal that explodes on contact with air or water due to its high reactivity with oxygen and water. When exposed to moisture or air, the sodium metal rapidly oxidizes, releasing hydrogen gas and heat in an explosive reaction.
It explodes on contact with water.
cause you put it in cold water... so it makes it cold.

The physical property of reactivity is observed when lithium reacts with cold water, producing hydrogen gas and forming lithium hydroxide. This reaction occurs because lithium is a highly reactive metal and readily reacts with water.
Sodium when placed in water explodes.
When steam hits cold metal and forms water droplets, it is called condensation.
The gas produced when sodium metal is added to cold water is hydrogen gas.
Stick it in cold water.
The metal that reacts slowly with cold water to form a hydroxide is magnesium. When magnesium reacts with water, it forms magnesium hydroxide and hydrogen gas.
warm water will rust metal faster
