What else can I help you with?
What happens to a substances temperature during a phase change?
stays the same
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 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
What happens when heat is added to a system?
When heat is added to a system, the temperature increases, unless there is a phase change taking place. In that case, temperature remains the same, and the only observable difference is the phase change.
What do the lines on a phase diagram represent?
The lines on a phase diagram represent the boundaries between the different phases of a substance (such as solid, liquid, and gas). These lines show the conditions of temperature and pressure at which two phases can exist in equilibrium with each other.
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 temperature during a phase change?
During a phase change, the temperature remains constant as the substance absorbs or releases heat energy to change from one phase to another. This is because the energy is used to break or form intermolecular bonds rather than raise or lower the temperature.
What happens to the temperature during a phase change?
The temperature* remains unchanged. * The heat (energy) content changes.
What phase change happens when glass mists up from breath?
Water in the vapor phase changes to liquid phase due to the cooler glass temperature.
What happens to a substances temperature during a phase change?
stays the same
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.
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 do you get a change of phase?
Change of phase is caused 99% of the time by a change in temperature or pressure.
When evaporation happens does the temperature increase or decrease?
When evaporation happens, the temperature decreases. This is because the energy required for the phase change from liquid to gas is absorbed from the surroundings, leading to a cooling effect.
What happens to the temperatures of a substance while it is changing state?
It can lose or gain energy or it forms the attractions between particles.
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.
