What phase changes release energy?
Gas to liquid change releases energy.
What happens to energy during a phase change?
Energy either transfers to the object or leaves the object.
Which type of energry is being transferreed during phase change?
Heat energy. Internal energy
Is energy required for each phase change?
Yes energy reqired during each phase change process. solid to liquid(water) = 333.7 Kj/kg liquid to vapour(water) =2257.1Kj/kg
What do you think will happen to the temperature of a substance during a phase change?
Typically, the temperature doesn't change during a phase change.
How does the the energy of a system change during a phase change?
energy is either absorbed or released during a phase change
How does the energy of a system change during phase change?
energy is either absorbed or released during a phase change
What happens to the energy during a phase change?
When energy is added during a phase change the energy is used to break molecular bonds.
What happens to the 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

Does the energy content of a substance change during a phase change?
Yes, but not the temperature.
Why does the temp of water not increase during a phase change?
These are phase changes - All the energy that is added at this time is used to change the phase of the substance.
What phase changes release energy?
Gas to liquid change releases energy.
What The heat of fusion of a substance is the energy measured during a?
phase change
Why doesn't the temperature change fast during a phase change?
Basically because there is energy needed for the temperature to rise or become lower, but energy is also needed to change the phase, so instead of the energy being used to change the temperature, it is being used to change the phase, therefore temperature does not change.
What happens to energy during a phase change?
Energy either transfers to the object or leaves the object.
