Which object has more heat energy a hot cup or a cold cup why?
The hot cup has more heat energy because temperature is a measure of the average kinetic energy of particles in an object. The hot cup has higher temperature, meaning its particles are moving faster, and therefore have more heat energy compared to the cold cup.
Does a cup of hot water have more heat that a pail of hot water?
Not necessarily. The amount of heat in a cup of hot water and a pail of hot water depends on factors like their temperature, volume, and material. In general, a pail of hot water will likely have more heat than a cup of hot water due to its larger volume and higher overall energy content.
When you feel the heat from a hot cup is that conduction?
Yes, feeling the heat from a hot cup is an example of conduction. Heat is transferred through direct contact between the hot cup and your hand.
How conduction is used in a hot cup?
In a hot cup, conduction is the transfer of heat from the hot liquid to the cup itself. The heat is conducted through the material of the cup, warming up the surface that we touch. This is why the cup feels warm to the touch when filled with a hot liquid.
How did the rate of heat loss from the hot cup change during the experiment?
The rate of heat loss from the hot cup likely decreased over time as the temperature of the cup approached that of the surroundings. Initially, when the cup was hot, the rate of heat loss would have been higher due to the temperature difference between the cup and the surroundings. As the cup cooled down and approached equilibrium with the room temperature, the rate of heat loss would have reduced.

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.
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.
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 did the rate of heat loss from the hot cup change during the experiment?
The rate of heat loss from the hot cup likely decreased over time as the temperature of the cup approached that of the surroundings.

When you pick up a hot cup heat is transferrd from the cup to your hand primarlyby what?
convection
