Which has the greater amount of internal energy: an iceberg or a cup of hot coffee? Defend your answer. The iceberg has the greater internal energy (“amount of heat”), because it has so very much more mass than the cup of coffee. This is true even though the temperature of the coffee is much higher.

Although an iceberg is cold and a pot of boiling water is hot, there is more heat energy in an iceberg because there are more molecules moving around.

Q: Could a block of ice have more thermal energy than a pot of boiling water? A: Yes, the block of ice could have more thermal energy if its mass was much greater than the mass of the boiling water.

A calorie is the energy needed to raise the temperature of 1 gram of water through 1 °C. So, yes, an iceberg in the North Atlantic does indeed contain more heat than your cup of boiling water by many trillions of times over.

Which has the greater amount of thermal energy-an iceberg or a hot cup of coffee? Explain. The hot coffee has a higher temperature, but not a greater internal energy. Although the iceberg has less internal energy per mass, its enormously greater mass gives it a greater total energy than that in the small cup of coffee.

In Celsius scale, water freezes at 0°C and boil at 100°C. 90°C. However, the swimming pool contains a lot more water. Therefore, the pool has more thermal energy than the cup of tea even though the tea is hotter than the water in the pool.

Warmer objects have faster particles and higher temperatures. If two objects have the same mass, the object with the higher temperature has greater thermal energy. Temperature is measured with a thermometer. Heat is the transfer of thermal energy between objects that have different temperatures.

Answer Expert Verified -The rate of the dye totally mixed with each container varies. -The dye mixes the fastest when dropped to the container having a hot water; the dye mixes slower when dropped to the container having tap water; and the dye mixes the slowest when dropped to the container having cold water.

Answer. it will take 2 mins to reach it ,if you put in in high heat and lid on.

For boiling 1 cup of water, it takes about 1 minute in a microwave, 2 minutes in an electric kettle, and 3 minutes in a pot on the stove. The time it takes to boil water depends mostly on the following factors: Amount of water. The container.

When water is boiled, the heat energy is transferred to the molecules of water, which begin to move more quickly. Eventually, the molecules have too much energy to stay connected as a liquid. When this occurs, they form gaseous molecules of water vapor, which float to the surface as bubbles and travel into the air.

Usually heating 2 cups will take slightly less than twice one cup, because of the cube-square law, the water won’t have twice the surface area. The faster you heat though, the less the difference will be. Also, if you literally heat two cups of water, like in a microwave, then it will take almost exactly twice as long.

answer: Cooling from 100 to 45 in a closed container, not sealed so you don’t get a vacuum, probably takes 100 minutes or so. min, but you said open pot, so it’s faster, as you get material loss (evaporation/”sensible heat”) as the water cools.

Answer: The temperature of the water increases. The water also releases bubbles and bacterias are being killed at this state. The water is also gradually decreasing as it evaporates in our atmosphere.

After boiling, what remain is the salt component since water will leave the beaker and evaporate turning liquid H₂O to gas H₂O. Letting water turns into gas so that salt component will be left from the container.

The molecules of water start moving with more kinetic energy. The temperature of the water increases. After that additional heat energy is consumed in converting water into water vapours. High energy molecules leave the water surface and go into the atmosphere in the state of vapours!!

Evaporation only happens on the surface while boiling happens throughout the liquid. This process is called boiling.

Boiling is the process by which a liquid turns into a vapor when it is heated to its boiling point. The change from a liquid phase to a gaseous phase occurs when the vapor pressure of the liquid is equal to the atmospheric pressure exerted on the liquid.

Answer: Boiling and condensation are the process involved in distillation normally. sometimes freezing is also used then it is called freezing distillation.

The process of distillation begins with heating a liquid to boiling point. The liquid evaporates, forming a vapor. The vapor is then cooled, usually by passing it through pipes or tubes at a lower temperature. The cooled vapor then condenses, forming a distillate.

Distillation is used to separate liquids from nonvolatile solids, as in the separation of alcoholic liquors from fermented materials, or in the separation of two or more liquids having different boiling points, as in the separation of gasoline, kerosene, and lubricating oil from crude oil.

(Whether she actually invented it is unclear.) But it wasn’t until the 8th century A.D. that Arabic alchemist Abu Musa Jabir ibn Hayyan designed the alembic pot still, a contraption that allowed for the effective distillation of alcohol.

Aeneas Coffey

Azeotrope, in chemistry, a mixture of liquids that has a constant boiling point because the vapour has the same composition as the liquid mixture. The boiling point of an azeotropic mixture may be higher or lower than that of any of its components.
