Why doesn't the temperature increase as the liquid changes into a gas?
During phase change from liquid to gas, the energy is used to break the intermolecular forces holding the liquid together rather than increase the temperature. This energy is called latent heat and is used to overcome the forces between molecules instead of raising the temperature. Once all the liquid has evaporated, then additional energy will go towards increasing the temperature of the gas.
Define temperature glide as it pertains to refrigerant blend?
Temperature glide refers to the range of temperatures over which a blend of refrigerants evaporates or condenses during a phase change process. This phenomenon occurs because the individual components of the blend have different boiling points, resulting in a temperature range rather than a single temperature for the phase change process.
What is the difference between latent heat and sensible heat in terms of their effects on temperature changes in a substance?
Latent heat is the energy absorbed or released during a phase change, such as melting or boiling, without affecting the temperature of the substance. Sensible heat, on the other hand, is the energy absorbed or released that does cause a change in temperature.
As heat is added to a substance undergoing a phase change the temperature remains constant because the energy is being used to?
break intermolecular bonds and change the phase of the substance rather than increase the kinetic energy of the particles (temperature).
Why does the temperature of a substance remain constant during it's melting point on boiling point?
Because of phase transition ie from solid to liquid during melting and from liquid to vapour during boiling. So just to change over from one phase to the other heat is totally utilized and hence no chance to have a rise in temperature. So temperature remains constant.
What happens the temperature during a phase change?
nothing
When the physical state of a substance changes during a phase what happens to the temperature of the system?
The temperature remain constant during a change of phase.
What happens to the temperature during a phase change?
The temperature* remains unchanged. * The heat (energy) content changes.
What happens to a substances temperature during a phase change?
stays the same
What happens to temperature after a phase change?
During a phase change, the temperature remains constant even though heat is being added to the system. This is because the energy is being used to break intermolecular forces rather than increase the temperature of the substance. Once the phase change is complete, the temperature will start to rise again.
Does the temperature of a substance change before the change of state is complete?
No. During a phase change the temperature is constant until the phase change is complete.
How does temperature change during change of physical change?
Temperature remains constant during the change in phase (physical state).
What do you think will happen to the temperature of a substance during a phase change?
During a phase change, the temperature of a substance remains constant. This is because the energy being absorbed or released is used to break or form intermolecular bonds, rather than to change the temperature of the substance.
Does the temperature of a substance changes before the change of state is completed?
No. During a phase change the temperature is constant until the phase change is complete.
A change of phase takes place at a constant?
A change of phase takes place at a constant temperature and pressure. During a change of phase, the substance absorbs or releases latent heat without a change in temperature.
What happen to the temperature during phase change?
The temperature remain constant.
What happens to energy added during a phase change?
The added energy is used in the phase change to break intermolecular bonds.It is used for the phase change. ~ APEX
