The molar enthalpy of vaporization of benzene at its boiling point 353.25 K is 30.8 kJ mol-1 What is the molar internal energy change?
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
What is ethalpy?

The sum of the kinetic and potential energy of the molecules of a substance?
thermal
Is the boiling point of one liter of water different from the boiling of 2 liters of water?
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.
Why does temperature remain constant during the boiling of water although is supplied?
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.
Which contains the most thermal energy - a boiling pot of water or a frozen lake?
Frozen Lake
The molar enthalpy of vaporization of benzene at its boiling point 353.25 K is 30.8 kJ mol-1 What is the molar internal energy change?
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
Where is the heat energy going when a substance is boiling?
The energy is used to maintain the temperature at the boiling point.
What is internal energy of an object?
the energy which absorved in the object is called internal energy
Where all the heat energy is going when a substance is boiling?
The energy is used to maintain the temperature at the boiling point.
What is Smoke is an example of an?
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.
What is the internal energy reserve in animal?
What is the internal energy reserve in plants
What is internal energy?
Internal energy is defined as energy associated with the random, disordered motion of the molecules.
What internal energy?
Internal energy is defined as energy associated with the random, disordered motion of the molecules.
How does he amount of energy change during boiling?
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.
What is the transfer thermal or internal energy?
the transfer in internal energy is also called heat
What requires more energy melting or boiling?
Melting requires energy input or absorption because liquid water has more energy than solid water.
