How does cold water turn in to hot water?
Heat it. Place a 300ml sample of the cold water in a 500ml beaker and place the beaker on a retort stand about six inches above a standard laboratory Bunsen burner. Turn on the gas and ignite the Bunsen burner. Allow the flame to heat the water for several minutes. When small bubbles begin to form in the water, shut off the Bunsen burner and measure the temperature. ...

What does a gentle flame on a Bunsen burner do?
A blue flame is neither too hot or too cold as somebody else has said. But the gentle blue flame is good for heating something up with a temperature that is between the yellow safety flame and the roaring blue flame. ...

How do you know the expansivity of a bimetallic strip?
You can test the bimetallic strip's expansivity by placing it in a hot or cold environment, such as a refrigerator or a Bunsen burner. The strip that contracts or expands more has a higher expansivity than the other. ...
How electric water heater works?
Basically a water heater is a big water tank with insulation wrapped around it. cold water will then flow into it and will activate a thermostat. The thermostat will then either kick on an electric heating element inside of the tank or will fire up a gas heating system at the base of the tank. Once the thermostat hits it preset temperature it then turns off the heating coil or burner. the tank is the filled with hot water ready for...

Why doesn't cold water make a hot burner cold?
Heat is a form of energy and due to the principal of thermodynamic equilibrium, will constantly seek a state of equilibrium. The reason a hot burner does not become cold is because as the energy is transferred to the cold water more energy is being put into the burner through either electricity or gas. If there was no source of energy to the burner, then the cold water would cool down the hot burner, though the cold water would also heat up...

What is an iron ring and how it is used?
What is an iron ring? !. An iron ring/clamp that holds glassware such as a funnels or other objects, like the a wire gauze or clay triangle for heating with a Bunsen burner. Often, the iron ring/clamp will be attached to an iron stand. How it is used? !. It's used to hold a flask in place while subjecting it to heat or cold. to use for oil lolipop to use for oil lolipop ...

How does cold water turn to hot water?
This has to be an honest question. There is a hot water heater. Probably in the basement next to the furnace. Can be heated with natural gas, electricity, oil or propane. Cold water come in, is heated with a burner at the bottom of the tank or with electrical heating elements in the side of the tank. ...

What are some convection currents in the home?
-- circulation of hot air in a gas cooking oven -- circulation of hot or cool air from heating/air-conditioning vents throughout the room -- circulation of heated water up to the outlet and cold water down to the burner, in a hot water heater -- continuous feed of the coldest water in the tea-pot down to the bottom where the burner is ...
Asked in Thermostats
Why does the thermostat keeps turning on and off?
Because that is its job! A thermostat is a device that measures the temperature of a given space or volume, and turns heating / cooling devices on and off accordingly. The thermostat in your house is designed to turn the heating off when the house is warm and turn it on when the house is cold. The thermostat in your car turns the radiator fan on when the oil / water temperature increases to a level that could be damaging to...
