When freezing happens is energy added?
No, energy is removed.
Why is Energy loss equal to Energy gain?
Whether total energy output is equal to the energy input depends on whether you have an isolated system. It is possible to put more energy into a system than leaves it and vice versa. In that case accumulation of energy in the system can be positive or negative. In general, the formula for the energy balance is: Energy in - Energy out = Change in contained energy (i.e. accumulation). Energy can be added to or removed from a system via work done on (or by) the system, heat added to or removed from the system, and mass added to or removed from the system. Energy can change form in a system or be added or removed from a system via such mechanisms as changes in kinetic energy, changes in potential energy, changes in pressure/volume, phase changes, changes in chemical composition (chemical reactions), etc. In steady state processes, accumulation has to be zero, so any energy input, by any means, must be balanced by energy output.
What happens to particles inside of a solid liquid or gas when energy is added compared to when energy is removed?
When energy is added the particles inside the substance vibrate more. Conversely, the vibrate less when energy is removed.
What is a set of particle or interacting components to which energy is added or from which energy is removed?
the answer is always B!
Does physical change occur when energy is added or removed?
Physical Change
When freezing happens is energy added?
No, energy is removed.
What is enthalpy of fusion vaporization?
Enthalpy of fusion/vaporization is the amount of energy added to a system to melt of boil a substance or the amount of energy removed from a system to condense or freeze a substance.

Is heat energy being added or removed during boiling?
added

Is heat energy being added or removed during the process of evaporation?
In condensation heat is removed In evaporation heat is added
When energy is added or removed is a physical change or chemical change?
Physical

What must be added to a system to break a bond?
Energy must be added to a system to break a bond.

The 3s.
