Does it take more energy to heat water at room temperature to 212 f?
yes it does
How much energy does it take to melt ice?
Heat because Ice and water would thaw out and begin to heat up
Why airconditioned cools room and why refrigerators warms room?
Air Conditioners and Refrigerators operate on the same principal - removing heat from one location and expelling it elseware. In this case, the fridge creates a much smaller "room" to be cooled, where as it would take much more energy to bring an entire room down to 1 or 2 degrees centigrade.
Why does water take so long to warm up?
The specific heat of water determines how much energy is needed to heat water.
How are heat and energy diffrent?
Heat is a type of energy. Thus heat is energy, but there are other forms that energy can take (such as sound, chemical, light, etc).
How is light energy converted into heat energy?
Light energy is converted into heat energy when plants take in sunlight (light energy) and convert it into heat energy when they respire and produce energy.
What do you have to do to heat energy to freeze a substance?
You need to take heat energy out of the substance.
What is form of the energy conversion that take place to combustion engine?
Heat energy is released in a heat engine when fuel is burned. The heat energy is then changed into mechanical energy.
What kind of energy does a candle take?
It takes the energy of heat.
What form does machines wasted energy take?
Usually, much of the wasted energy takes the form of heat energy. However, part of the energy can also be in other forms, for example sound.
What is the energy conversions that take place until the electricity is produce to coal?
Chemical energy> Thermal(Heat) energy Heat energy> Rotating mechanical energy
How can you generate heat energy?
take a dump! :)
