A teaspoon of boiling water contains more internal energy than a pan full of water at 50 C.
a pan full of boiling water cointains more internal enery because it has a larger mass
The pan. Because it has a larger mass.
It should be 0 as internal energy is a function of temperature, i.e: U (T) At the boiling point, there is no change in temperature, and hence DU= 0
Internal Energy
thermal
No, boiling point is not affected by volume. What will change is the amount of energy you need to put in to get it to boiling point.
The boiling water at its boiling point uses the extra energy being supplied to transform its state from liquid to gas (steam) at the rate of 540 cals per gram. Now if you have the water boiling in a pressurized vessel you can make the water boil at a higher temperature and this is used in certain applications but the temperature will remain constant at that pressure as long as there is water to be converted to steam.
Frozen Lake
It should be 0 as internal energy is a function of temperature, i.e: U (T) At the boiling point, there is no change in temperature, and hence DU= 0
The energy is used to maintain the temperature at the boiling point.
the energy which absorved in the object is called internal energy
Smoke is an example of mechanical energy and heat energy. This is because the internal motion of atoms is called heat energy and mechanical energy is energy associated with motion. Smoke contains atoms moving which is both an example of heat and mechanical energy.
The energy is used to maintain the temperature at the boiling point.
What is the internal energy reserve in plants
Internal energy is defined as energy associated with the random, disordered motion of the molecules.
Internal energy is defined as energy associated with the random, disordered motion of the molecules.
During boiling the temperatre of the boiling liquid does not go up. The energy input into the boiling liquid is taken away as the latent heat of evaporation by the escaping gaseous phase.
the transfer in internal energy is also called heat
Melting requires energy input or absorption because liquid water has more energy than solid water.
