yeah but It would take like over a year or something. So you can try and yell for a year if you want
A cup of coffee is an example of convection because the heat from the water warms up everything in the cup and all the atoms are bouncing off the cup[ in the coffee] of coffee because the coffee is hot.
Yes, just about all one-cup coffee makers are faster than the typical 10-cup brewers. They heat the water up much faster. For an even faster cup of coffee, consider the Keurig machines that will have you drinking a hot cup of coffee in under two minutes.
It depends on how big the coffee cup is.
A cup of coffee loses heat by:conduction - heat from the coffee enters the table topconduction- the hot coffee warms any milk or sugar added lowering the overall temperatureconvection - warm air (heated by the coffee) rises up by convention carrying the heat away.convection in the fluid in the cup brings the hottest fluid to the top allowing speedier evaporation.radiation - all bodies warmer than their surroundings radiate heatevaporation - the steam over the hot coffee is water vapor using the coffees heat to evaporate and escape the fluid
The boiler will heat up the water that comes out of the tap or is used in the radiators. Also the kettle will heat up cold water to make a cup of coffee or tea
You just go up to them and say..."May I please have a cup of coffee?"
You yawn, stretch, and drink a cup of coffee.
First pour boiling water into the cup to heat it up Then makesure you use an insulated one with air pockets, vacumn or all lid - all three of these will keep your coffee for around a day !
The sand will heat up faster.
The cost of a cup of coffee (6 oz) is determined by the cost of the coffee and the strength you prefer. I use one quarter cup Folger's Classic Roast per 10 cup brewer. The coffee is $0.30/oz and the cost is $0.03/cup.
You will want to use a coarse grind for the vacuum coffee maker. If you have a fine grind you will end up with coffee grounds in your coffee.
Heat transfer to cups (or other solid objects) happens on a molecular level; fast moving hot molecules (perhaps in your hot coffee) collide with slower moving cold molecules (in your cup) and speed them up, giving up some of their own momentum.
