The cup with
hot boiling water
has more thermal energy than the cup with freezing cold water because the molecules are moving faster, which equals MORE total kinetic energy.
Which contains more heat thermal energy a mug full of boiling water or a bathtub of room temperature water?
Suppose you were to compare a milliliter of water near the boiling point with a bathtub full of water at room temperature. The bathtub contains a billion times as many water molecules, and therefore has a higher total kinetic energy and more heat.
Does a cup of boiling water have more thermal energy than a bathtub of warm water?
A cup of boiling water may have a
higher temperature
than a bathtub of warm water because the average kinetic energy of the particles is higher. However, if you were to sum up the kinetic energy of all of the water molecules in the tub, it would have a higher total thermal energy.
How much thermal energy does boiling water have?
At 1 atm, water freezes at 0° C and boils at 100° C. The energy required to change water from a liquid to a solid is 333.7 kJ/kg while the energy required to boil water is
2257 kJ/kg
.
What has a higher thermal energy a cup of boiling water or an iceberg?
Answer:
Boiling water
has a lot more heat than the oven’s air (even though the air has a higher temperature). The oven’s air is less dense than the pot’s water. An iceberg has a lower temperature than a burning match, but much more heat!
Which is hotter a red hot nail or a bathtub filled with ice water?
To see the difference, consider a red-hot nail and a bathtub full of
tepid water
. … This is because the nail has the higher average kinetic energy (higher temperature), but the water contains far more atoms and thus far more total heat energy than the nail.
Which has more kinetic energy a 2l of boiling water or a cup of boiling water?
Temperature is a measure of the AVERAGE Translational KE ONLY! Heat is a flow of thermal energy from hotter to colder because of a difference in temperature.
(think water fall!)
There is twice as much molecular kinetic energy in 2 liters of boiling water as in 1 liter of boiling water.
What happens to a hot cup of tea as it reaches thermal equilibrium?
Long experience tells us that, over time, the tea will get cooler and the surrounding air will get warmer until the air and the cup of tea reach thermal equilibrium. … The result is that
the decrease in the internal energy of the cup of tea is equal to the increase in the internal energy of the air
.
What happens to water when you heat it to 100 C?
When heat is added to a pure body of water at 100° Celsius the temperature does not change. What happens instead is that
the water beings to boil
. This example is known as a change of state or a phase change.
Does boiling water release energy?
VAPORIZATION
When water reaches its boiling point of 100oC, water molecules are moving so fast that they break free of the attractions that hold them together in the liquid state. … CONDENSATION When steam is cooled, it releases thermal energy and turns into its liquid state. This process is called condensation.
What happens to water when you heat it?
When water is heated,
it evaporates
. The molecules move and vibrate so quickly that they escape into the atmosphere as molecules of water vapor. … Water is evaporating, but staying in the air as a vapor. Once water evaporates, it also helps form clouds.
Does ice have more thermal energy than hot water?
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.
What has more thermal energy water or ice?
Item EG054002: Water has more thermal energy
than ice
because the molecules of water are moving faster than the molecules of ice. The ice has more thermal energy because it is a solid and the water is a liquid. The water has more thermal energy because the ice has no thermal energy, but the water does.
Which has more energy an iceberg or a bucket of red hot molten metal?
An iceberg could even contain more
heat
energy than a cup of coffee or a red-hot iron bar. That’s because its bigger and contains so many more molecules, each of which has some heat energy. The coffee and the iron bar are hotter (have a higher temperature), but the iceberg holds more heat because it’s bigger.
Are heavier atoms hotter?
This question originally appeared on Quora.
Yes
. Temperature differences means that there is a different amount of kinetic energy in the motion of the atoms of the two bodies. …
What is happening to the glitter as the water gets hotter?
The glitter
flows from the high heat in the center to the outsides where it is cooler
. Convection transfers heat (energy) by currents of gas or liquid. (It may help to have students get up and walk past the demonstration so that they can get a closer look.)
