# Its sensible temperature can increase, # It can undergo a phase change (solid->liquid, liquid->gas, gas->plasma, or solid->solid with atomic arrangements), or # A chemical / physical reaction can be triggered (diffusion in semiconductors, curie temperature in magnets, have a pretty sharp temperature thresholds).

How will the substance change if energy is added to the liquid at 20 degrees celsius?
the substance will get hotter.
Why may the temperature of a substance change when energy is added?
Thermal energy of a substance is determined by the movement of the molecules and the potential energy of the arrangement of molecules. Heat transfer will stop when thermal equilibrium is reached. It depends upon the substance how long that takes.
What happens when energy is taken away from matter?
The substance's particals will start slowing down and come closer together. As kinetic energy is removed from a substance, it will do the opposite as when kinetic energy is added to a substance.
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 will happen to happen to the state of the substance the atomic or molecular activity and the shape of the graph when thermal energy is added?
When you add thermal energy you are going to do two things: you will cause a progressive change of phase from solid to liquid to gas to plasma, and you will raise the temperature causing increased atomic/molecular activity. Unless you identify the axes of the graph, I don't know what graph you are talking about and can't talk about the shape of whatever it is you are graphing.
What has to be added to a substance to cause a phase change?
Heat energy must be added to or subtracted from a substance to cause a phase change.
When energy is added to molecules what happens to the substance?
they spread apart and move faster when energy is added.
How will a substance change if energy is added to the liquid at 20 degrees Celsius?
The substance will get hawter
How will the substance change if energy is added to the liquid at 20 degrees celsius?
the substance will get hotter.
Why does evaporation require that heat energy be added to a substance?
Heat is energy the substance needs to change it's state of matter (the more energy a substance has the higher it's temperature)
What means energy is added to the substance as it changes state?
it vaporizes

Thermal energy added to a substance that is not changing state causes the substances temperature to do what?
To increase.
What substance can change from a liquid to a gas on its own without energy needing to be added?
water
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.
