starting from absolute zero, even twice as much water as the tea would contain more heat. Even starting at 0 Celsius underwater volcanoes would heat water far beyond boiling. On a percentage of heat the tea would win.

How is heat energy transfed from the cocoa to the spoon?
Assuming you have a cup of hot cocoa, then the heat transfer is by conduction
What is called when you pick up a hot cup and the heat is transferred to your hand?
This is conduction
What is the difference between heat and temperture?
Heat is the AMOUNT of energy, Temperature is the CONCENTRATION of heat energy. For example; An iceberg (a big one) will have more heat energy than a cup of coffee (fresh and hot).
How is heat transferred when a cup of hot coffee is placed in a freezer?
Heat can beradiated,conducted or travel byconvection or a combination of these three.The base of the cup would conduct the heat to the surface it is sitting on and the body of the cup would radiate the heat and the air in the freezer would transfer the heat by convection currents.
What if A woman picks up a cup of hot cocoa and feels her hands get warmer. What statement best explains what is happening?
That means that heat energy is transferred from the hot cup, to the hands.
The rate of heat loss from the hot cup change during the experiment answer?
The rate of heat loss from the hot cup decreased during the experiment.
What can you add to a paper cup to keep hot drinks hot for longer?
The thermal conductivity decreases when a paper cup (or another paper cup) is added. Intuitively, the heat has to pass through more layers. This is Fourier's Law of Heat Conduction - lower thermal conductivity means less heat loss.
A hot cup of coffee loses heat faster than a warm cup Why doesnt the hot cup reach room temperature before the warm cup?
The hot cup loses heat faster, but only until it becomes a warm cup itself. Then it loses heat as the warm cup did at the beginning. However, by this point, the hot cup is warm, but the warm cup is now cooler too. Therefore, the warm cup will still become room temperature first.
Will a liquid remaine hot longer in a plastic cup or in a metal cup?
It depends on which one radiates heat fastest. Since plastics are generally poor heat conductors, you'd expect the plastic cup to cool more slowly. But a thin plasic cup, painted black, may radiate more heat than a very shiny metal cup.
Does a cup of hot tea or a picture of lemonade have more thermal energy?
Possibly, if the pitcher was large enough. Heat and temperature mean two different representations of heat energy. Heat is the absolute value, temperature is the average value. For example, a swimming pool at 25 deg C has more heat contained within it than a cup of water at 25 deg C. However the swimming pool has the same temperature as the cup of water. Since heat is based on the absolute value, which is proportional to the amount, a pitcher of lemonade may have more overall heat than a small cup of hot tea, although the temperature of the tea would be higher than the pitcher of lemonade.
How do you keep hot water hot in a cup?
try covering the glass, so the heat particles stay inside the cup, and the hot water stays hot.
How do currents heat in the ocean?
the radiation from the sun will send heat to the ocean and the heat would make currents hot Basically a convection current
When you pick up a hot cup heat is transferrd from the cup to your hand primarlyby what?
convection
Will a metal cup or a styrofoam cup keep the hot water warm after a short time?
It is the Styrofoam cup as it is not a good conductor of heat but the metal cup is a good conductor of heat.
Where does the heat go from a cup of hot cocoa sitting on the table?
Hot air rises.
What is scientific heat?
Strictly speaking, heat is the total amount of thermal activity within a given volume. Temperature is the average amount of heat within a given volume. For example, a hot cup of coffee has a higher temperature than a bathtub full of warm water, but the tub of water contains more heat than the hot cup of coffee.
How does a bath of hot water at 40 Degrees have more heat energy than a cup of tea at 90 degrees?
It has a much higher volume of water compared to the tea cup. It takes less energy to heat a small amount of liquid such as a tea cup.
