If the water in the cup came from the kettle, it will be cooler than the water that remains in the kettle. Since the water in the cup is more exposed to the air than the kettle it will lose heat to evaporation more quickly than the water in the kettle will. The cup will also conduct heat way from the water until the water and the cup are the same temperature, whereas the kettle is already as hot as the water it contains.
thermos cup
A kettle is used for boiling water usually used for making a cup of coffee or tea.
china cup
A paper cup typically does not keep water hotter than a plastic cup. Paper is a poor insulator compared to plastic, so heat is more likely to escape from a paper cup, leading to faster cooling of the water inside.
Boil some water to make a cup of tea or coffee
Cup,teapot,kettle,pail,tub
The cup of water is as hot as the bath tub full of water as they are at the same temperature.
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 .
Take half cup of milk and water. Then put it in a kettle . Then keep it on gas stove . When it will boil off the gas stove. Take kettle and put it in cup . Now your tea is ready.
A black cup will get hotter in the sun compared to a white cup. This is because black objects absorb more light and heat than white objects, which reflect more light. The absorbed heat will cause the black cup to warm up faster.
It will stay cooler or hotter depending on what it originally was.
Put teabag in cup, boil kettle, let water cool for a bit, then pour it in.
