You would need a source of power giving at least 500watts to heat a cup in reasonable time. You could obtain this from a lead acid cell such as a car battery. At 12v you would need a current of say 50 amps (this would give 600watts). So the heating coil should have a resistance of 12/50 ohms = 0.24 ohms. The connectors to and from the battery would need to be rated for 50 amps without heating up appreciably.
What else can I help you with?
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.
How did the heat energy received by the cup of soil to the heat energy of received by the cup of water?
The cup of water will receive more heat energy compared to the cup of soil because water has a higher specific heat capacity than soil. This means water can absorb more heat for a given temperature change compared to soil.
Which can trasfer more heat a cup of bioling water or a cup of tap water?
tap water
If ice melts in cup of water what produces in the cup?
Heat
What evaporates faster a cup of water by the sun or a cup of water boiled?
a cup of water that is boiled since it gives more heat.
What happens to the heat stored in the metal when the metal is poured into the Styrofoam cup of water?
When the metal is poured into the Styrofoam cup of water, the heat stored in the metal is transferred to the water and the cup. This transfer of heat causes the temperature of the water and the cup to increase, as the metal cools down.
Which can transfer more heat 1 cup of boiling water or 1 teapot of boling water?
The cup.
If you place a cup of sand and a cup of water in the sun which one will heat up faster?
The cup of water will heat up faster than the cup of sand because water has a higher specific heat capacity, meaning it requires more energy to increase its temperature compared to sand. Sand, being a solid, has a lower specific heat capacity and will heat up more quickly.
How did the heat energy received by the cup of soil compared to the heat energy received by the cup of watr?
The cup of soil would receive less heat energy compared to the cup of water because soil has a lower heat capacity and thermal conductivity than water. This means that soil would heat up or cool down more slowly than water when exposed to the same amount of heat energy.
Which can transfer more heat 1 cup or boiling water or 1 teapot of boling water?
One teapot of boiling water can transfer more heat than one cup of boiling water because the teapot has a larger volume and surface area for heat transfer. The greater quantity of boiling water in the teapot allows for more heat to be transferred compared to the smaller amount in a single cup.
Will water heat more in a black cup or a white cup when sitting in the sun?
Water will heat more in a black cup than in a white cup when sitting in the sun because black absorbs more light and heat energy, while white reflects it. This means that the black cup will absorb more heat from the sun's rays, warming up the water more quickly.
How is energy transferred from a cup of boiling water?
Energy is transferred from a cup of boiling water through convection, conduction, and radiation. Convection causes the hot water at the bottom to rise, transferring heat to the cooler water at the top. Conduction transfers heat from the water to the cup, and radiation emits heat in the form of infrared waves.
