What happens if cold water is on flesh to long?
Hypothermia
What happens when a cold spoon is placed near the vapour of boling water?
When a cold spoon is placed near the vapor of boiling water, the water vapor cools down and condenses into water droplets on the surface of the spoon. This happens because the cold temperature of the spoon causes the water vapor to lose energy and transform back into liquid form.
Does warmer water rise or fall in cold water?
Warmer water rises in colder water. When heated, water expands and becomes less dense, causing it to rise and displace the colder, denser water. This movement of warm water rising and cold water sinking forms a process known as convection.
Water vapor and air inside an aluminum container are heated to a high temperature The container is then submerged in ice cold water Why does the aluminum container collapse?
When water is heated, water vapor forces the air out. When submerged in cold water, the water vapor condenses instantly, leaving a partial vacuum in the can, Atmospheric pressure (14.7 psi) acting on the outside of the can crushes the can before air can rush through the opening in the can to balance the pressure. Fun science experiment, just be careful not to get burned.
What is one reason that room temperature water boils faster than cold water?
Room temperature water boils faster than cold water because it is closer to the boiling point, requiring less energy to reach that point. Cold water must first be heated to room temperature before it can reach the boiling point, delaying the process.
What happens to a can when heated and transferred to cold water?
The can collapses and closes in on itself.
When the car stops what causes the heater to go cold?
The heat for the interior of your car comes from the heated radiator coolant. When you are driving down the road the water pump circulates the heated engine coolant. If the engine slows and the water pump isn't real efficient you might get cooling in the heater. When you turn off the engine you aren't getting warm water pumped into the heater.
You can not start your Mercedes Benz car when engine is hot however it easily start when engine is cold?
Yes the reason for that is because the engine is over heated and when its cold the engine is nice and cold perfect for starting conditions.
What happens to the molecules of air when they are heated?
they get exited and move faster than cold molecules
Does water flow from hot to cold?
No, cold water is piped into the hot water tank and is heated by electricity or gas, it then flows out to the hot water taps.
What happens when a fluid starts to cool down after being heated?
it gets coldit gets cold
What happens when hot water meets cold water?
cold water is much heavier than hot water . the water becomes warm
Is hot water denser than cold water?
NO, it is the opposite. remember molecules expand when heated
What metal does not react with cold water but reacts with steam when heated?
Iron and Zinc
How can I prevent my dog's water from freezing in cold weather?
You can prevent your dog's water from freezing in cold weather by using a heated water bowl or placing a heated water dispenser near your dog's living area. Additionally, you can check the water frequently and refill it with warm water to prevent freezing.
What is the function of the cold water inlet in a water heater system?
The cold water inlet in a water heater system brings in cold water from the main water supply into the tank, where it is heated up to provide hot water for household use.
What will happen to a drop of food coloring when added to a cup of heated water?
The food coloring will spread throughout the water and become homogeneous faster than it would in cold or warm water. The food coloring would also mix evenly with the water faster if you stirred the water after adding the food coloring. This happens because the molecules are moving faster when they are heated up stirred.
