What energy is required to create a phase change without changing the temperature?
It is called the latent heat of vaporisation.
How does the temperature of gas change when it is compressed if the process is adiabatic?
In an adiabatic process, the temperature is increased when it is compressed. There is an increase in internal kinetic energy, and because temperature is related to kinetic energy, it is also increased.
What is a latent heat energy levels?
Latent heat- the amount of heat required by a system/ substance to change phase. It's also heat absorbed or radiated during a change of phase at a constant temperature and pressure.
How does a thermometer help when comparing the energies of particles?
A thermometer measures the amount of thermal energy a material has. This thermal energy is related to the vibrational and rotational energy the particles in the material have. By using the thermometer to measure the temperature of a material you are, in effect, measuring the amount of energy the particles of that material have.
What increases when the average Kinetic energy of the particles in a material increases?
The average kinetic energy of colliding particles can be increased by increasing temperature.
Materials with a high specific heat can absorb a lot of energy and show little change in temperature?
Yes. Specific heat capacity is the amount of heat energy required to change the temperature of the material, so a material with high specific heat needs a lot of heat energy for its temperature to go up.
The specific heat of the material is?
specific heat content is calculated by the joules of energy required to change the temperature of one cubic centimeter of the material 1 degree Celsius.
The amount of heat energy required to raise the temperature of a unit mass of a material one degree is?
Heat capacity is the amount of heat energy required to raise the temperature of a unit mass of a material one degree.
Why you calculate enthapy?
Generally enthalpy is analgous to the energy of a material at a particular temperature and pressure. It is calculated to determine the energy a material holds, or more often, enthalpy differences are calculated to determine how much energy is required to bring a material from one temperature and pressure to another temperature and pressure.
How does temperature relate to amount of energy present in a substance?
Higher temperature means greater energy content compared to a lower temperature. The energy required to change the temperature is proportional to the mass of the system, the specific heat capacity, and the temperature change.
The heat of fusion is defined as the energy required at constant temperature to change 1 unit mass of a?
The heat of fusion is the amount of energy required to change 1 unit mass of a solid to a liquid at constant temperature.
What is specific latent heat.?
It is the amount of energy required to change the state of 1kg of a substance with no change in temperature.
What is specific latent of fusion?
It is the amount of energy required to change 1kg of solid into a liquid with no temperature change.
What means that a large amount of energy is required to change the waters temperature?
Specific heat
Why does the temperature not change during a phase change?
During the change of state, the molecules of a substance absorb energy to overcome the strong intermolecular force of attraction between them. Hence the heat energy which we supply is absorbed by them for this purpose. So change in temperature is not observed.
What is specific latent heat of vaporisation?
Is the amount of energy required to change 1kg of liquid into gas with no temperature change.
Can a material gain energy and not change temperature?
Yes quite possible. This occurs at the change of state. As water gets changed into steam heat will be supplied but the temperature would remain at the boiling temperature.
