What phase change from liquid to gas will take place if you add energy equal to the heat of vaporization?
The liquid will boil.
What can a boil be defined as?
Boiling, a type of phase transition, is the rapid vaporization of a liquid, which typically occurs when a liquid is heated to its boiling point, the temperature at which the vapor pressure of the liquid is equal to the pressure exerted on the liquid by the surrounding environmental pressure.
What will happen to bring a substance from a liquid to a gas?
The phenomenon is called evaporation (the transformatiom occur at low temperatures, at the surface of the liquid) or vaporization (the transformatiom occur at high temperatures - boiling in the total volume).
Why is gravitational potential energy equal to kinetic ebergy?
Gravitational potential energy is not equal to kinetic energy:MGY doesn't always equal (1/2)mv2. This holds true in the CHANGE of gravitational potential energy being equal to the CHANGE in kinetic energy because of the Law of Conservation of Energy, Mass, and Charge.
How does kinetic energy of solids liquids and gases compare?
The kinetic energy is lowest in solids, higher in liquids, and highest in gases.
What phase change from liquid to gas will take place if you add energy equal to the heat of vaporization?
The liquid will boil.
Why is the enthalpy of sublimation is equal to the sum of enthalpy of fusion and enthalpy of vaporization?
Enthalpy is a state function, and to a first approximation does not depend on temperature. So the change in enthalpy to go from solid to a gas directly (sublimation) at some temperature is equal to the sum of the enthalpies associated with going from a solid to a liquid (fusion) and going from a liquid to a gas (vaporization) at other temperatures.
What does latent evaporation equal?
Latent evaporation is the amount of energy required to convert a liquid into vapor at a constant temperature. It is equal to the latent heat of vaporization of the substance being evaporated.
Is heat of vaporization for water is equal to heat on condensation of water?
Yes, the heat of vaporization for water is equal in magnitude but opposite in sign to the heat of condensation. This means that the amount of energy required to vaporize water is the same as the amount of energy released when water vapor condenses back into liquid water.
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?
The molar internal energy change can be calculated using the equation: ΔU = ΔH - PΔV, where PΔV is the work done during the phase change. For vaporization, at constant pressure, the work done is approximately zero, so the molar internal energy change is approximately equal to the molar enthalpy of vaporization. Therefore, the molar internal energy change in this case is 30.8 kJ mol-1.
What can a boil be defined as?
Boiling, a type of phase transition, is the rapid vaporization of a liquid, which typically occurs when a liquid is heated to its boiling point, the temperature at which the vapor pressure of the liquid is equal to the pressure exerted on the liquid by the surrounding environmental pressure.
The temperature at which the vapor pressure of a liquid is equal to the external pressure is the what?
The temperature at which the vapor pressure of a liquid is equal to the external pressure is known as the boiling point. At this point, the liquid changes to a gas by overcoming the external pressure.
How much energy is released during condensation?
During condensation, the energy released is equal to the latent heat of vaporization of the substance. This energy comes from the conversion of the gas state to the liquid state, causing the gas molecules to slow down and release energy in the form of heat.
Does the mass of liquid affect the rate of temperature change?
Sure. Other things being equal, you need more energy to raise the temperature of a larger mass of liquid.
What will happen to bring a substance from a liquid to a gas?
The phenomenon is called evaporation (the transformatiom occur at low temperatures, at the surface of the liquid) or vaporization (the transformatiom occur at high temperatures - boiling in the total volume).
What does energy pressure mean?
Pressure energy per unit volume is equal to the pressure and per unit mass is equal to the density of the liquid. When an incompressible liquid flows out of a tank in which the pressure is maintained , the liquid under pressure possesses potential energy.
If work done on an object is equal to object's change in kinetic energy this the state of?
If the work done on an object is equal to the object's change in kinetic energy, then the object is in a state of work-energy theorem. This theorem states that the work done on an object is equal to the change in its kinetic energy.
