∙ 6y agoThe heat source is at the bottom of the pot, so the water there gets hot first. Hot liquids expand, making them lighter than the surrounding cooler liquid. This rising hot water is a convection current. As it move up to the top of the pot, cooler water moves down to replace it.

∙ 13y agoWhile the tea cools down, part of the heat will go away through infrared radiation - that will be absorbed by the walls/roof of your house and get converted back to heat - or it will radiate into outer space, if you are outside your house. The remaining heat will heat up the atmosphere, through conduction and convection.

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.
Why are we able to sip hot tea or milk faster from a saucer rather than a cup?
Because the rate of evaporation depends upon the surface area exposed to the atmosphere. The surface area of a saucer is greater than that of a cup which makes it easier for tea to evaporate rapidly which thereby makes the tea cool.
Is porcerlain cup an insulator?
porcelain is a bad conductor of electricity or current, It is a very good Insulator used in all electrical installations throughout the world. mostly we use in household item as tea cup and Saussure's, as porcelain cup can not conduct heat from inside to outside we hold it cup normally evnthough inside tea is hot.
How can a cup of very hot tea have less thermal energy than a kettle of lukewarm water?
Even though the cup has very hot water it still has less thermal energy than the kettle because the kettle is larger than the cup therefor it has more liquid and more liquid = more molecules and the more molecules the more the heat energy ( thermal energy ) It does not matter how fast the particals are moving just how many there are , the cup has a lot less particals than the kettle so it has less thermal energy. This was wrote by an 11 year old just think about that .
When a cup of hot tea cools down is that a chemical change?
physical change
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.
When a spoon is dipped into a cup of hot tea the heat from the tea is eventually felt in the handle of the spoon what method of energy transmission is responsible for this heat transfer?
metal radiation transmission
Why a spark of firework will not hurt you as much as a cup of hot tea?
a spark from a fire work may be very hot but it will not hurt very much because it does not contain much heat energy however even though a cup of tea may not be very hot it can still burn the tongue because it contains a lot of heat energy.
What type of energy is a hot cup of tea?
The heat is thermal energy, but it also has several other forms of energy (including mass energy, potential energy, chemical energy, etc.)

When Javier touches a hot mug of tea energy is transferred from the surface of the mug to his hand. What kind of energy is this?
The transfer of heat from cup to hand is known as conduction.
What in the house uses conduction?
A spoon in a cup of tea.If a spoon was left in a hot cup of tea conduction would happen. Particles in the part of the spoon that is in the hot cup of tea will use the heat/thermal energy of this as kinetic energy. These particles will then pass this kinetic energy (whilst still keeping some in themselves,) to the particles next to them. This will continue until all the particles in the spoon have kinetic energy.
How does a hot cup of tea cool the body better than an ice cream?
Yes, tea cools better than an ice cream. During hot weathers, sweating remains the most effective way of cooling down the body and ice-cream does not cause sweating. Hot tea is cooling on a hot day mainly because it causes the body to lose sweat. Sweating is one of the body's main cooling mechanisms. When liquids evaporate, they need energy in the form of heat. If, like sweat, they are on the skin, then they use the body's heat to evaporate, so the body loses heat.
Why do liquids cool down when its hot?
the heat leaves the tea and enter the atmosphere as energy
How can you get an Asian cup of hot tea?
tea
Why can you make a cup of hot tea sweeter than a cup of iced tea?
Hot tea is capable of dissolving more sugar than iced tea.
Why do hot tea remain hot in white cup than in a dark cup?
I know this might sound strange but it's when the heat is reflected back into the cup the same way light is. Dark cups absorb the heat causing conduction. Hope this helps!
