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.
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
.
Does 4 cups of boiling water have the same thermal energy as 2 cups of boiling water?
Does 4 cups of boiling water have the same thermal energy as 2 cups of boiling water? Temperature is the average kinetic energy of particles of matter. Thermal energy is the total kinetic energy of particles of matter. … It's determined that
both cups of water have the same amount of thermal energy
.
Is boiling water thermal energy?
Boiling water on a stove is an example of
thermal energy
. Thermal energy is produced when the atoms and molecules in a substance vibrate faster due to a rise in temperature.
Which cup has the most thermal energy?
Which cup of
coffee
has more thermal energy? The coffee in the cup on the right would have more thermal energy because the particles are moving at a much faster rate than the coffee in the cup on the left. Temperature is measured using a thermometer.
Which has more total energy a cup of boiling water at 100?
Correct!
The swimming pool
at 90°C has more energy. The cup of boiling water at 100°C has more energy.
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.
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.
How many joules does it take to heat 1 Litre of water?
The energy needed E=SH times change in temperature times the total mass in grams(Which is 1000gram for a liter of water). That gives you 4.184•79•1000 which is
330,536J
, or 330.54KJ.
Which has more thermal energy a glass of water or a pool?
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. … This is because the large beaker contains more water and needs more heat energy to reach 100°C.
What has more thermal energy an iceberg or boiling water?
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.
What has the most thermal energy?
Matter in its gas state
has the most thermal energy than when it is a solid or a liquid. Because gasses have more thermal energy than others, they move differently than others.
Why does the ice not melt even though the water is boiling at the top?
Why does the ice not melt even though the water is boiling at the top? … When ice is wrapped in wire gauze and placed in water it does not melts even when the water boils because
the container is made up of insulating material
. Due to no heat transfer heat will not able to hit into the ice and it remains intact.
Will boiling water melt ice?
The hot water produces heat to melt the ice
, while the rubbing alcohol speeds up the melting process due to its low freezing point.
Why does ice melt slower in salt water?
Salt water freezes at a lower temperature than the 32 degrees F at which freshwater freezes.
The difference between the air temperature and the freezing point of salt water is bigger than the difference between the air temperature and the freezing point of freshwater
. This makes the ice with salt on it melt faster.
