First, it'll change it's temperature, and with this comes change in size, usually expansion.
Then it can change its physical properties, it can become softer, or harder.
Next you may change its phase: If you're starting out with a solid, it may melt to liquid phase; a liquid may go to gas phase; a gas may go to plasma phase.
Or, if oxygen is available, eventually it may start to burn.
Or, depending on the material, which could well be a mixture of different molecules, these might interact with each other, or they might fragment into smaller molecules.

What happens when a liquid doesn't have thermal energy?
Any object above zero kelvin - in other words, any object - has thermal energy. If you cook down a liquid - reduce its thermal energy - it will sooner or later get cold enough to become a solid.
Why is heat an unusable energy?
Thermal energy is useful energy. However, thermal energy is usually just heat, and not very hot heat at that. And heat, unless hot enough to boil water is a bit difficult to move and to convert into other kinds of energy. You can't run an electric motor directly off thermal energy for instance. But if you live somewhere where homes needs to be heated as opposed to cooled then thermal energy most certainly can come in handy.
Vibrating objects produce this energy?
It can be thermal energy if it is the atoms vibrating in a solid material. If the vibration is large enough it can cause acoustic energy, if the vibrating object is coupled to the atmosphere. If an object is vibrating in a magnetic field it can give off electromagnetic energy.
What enery tranformation takes place when rubbing your habds together?
thermal energychemical energy is transferred to thermal, sound, and motion energy. Thermal
Which of these has the least amount of energy solid gas or liquid?
E(gas) > E(liquid) > E(solid) That is, the solid has lowest energy, and has has highest energy. Because you have to put energy into the material to melt and then boil it. In more detail... First the material is solid, in a nice stable low energy state. By heating the material you are transferring energy into the material. When you have put enough energy in you disrupt the van der waals forces and the material melts. Now you have a liquid which must be a higher energy because you put energy into it to melt it. Similarly, to boil the liquid you must add sufficient energy so the molecules can completely overcome the van der Waals forces to enter the gas phase.
How can a liquid expand without changing state?
A liquid can expand when thermal energy is absorbed which is known as thermal expansion, but the thermal energy is not enough to change the liquid's state. When there is enough thermal energy, the liquid may change to a gas if the particles move fast enough to escape the liquid or it may change to a solid if the thermal energy is released from the matter.
Convection currents carry thermal energy from the sun to Earth?
No. Convection requires a medium to carry thermal energy from one place to another. There is no or not enough of any material in space to accomplish this. Radiation will carry thermal energy from the sun to the Earth.
Does melting los or gain thermal energy?
A solid melts when it gains enough thermal energy.
What happen-eds during condensation?
the particles in a gas lose enough thermal energy to form a liquid.
If you slide a crate across the floor kinetic energy is converted to thermal energy as it comes to rest. Why will adding thermal energy to a stationary crate not cause it to move?
# cos nothing is converting it to kinetic energy # if you add enough thermal energy the box will burn and "move" :)
A person places a metal spoon that is at room temperature into a bowl of hot soup how will the thermal energies of the spoon and the soup be affected?
the spoon will increase in thermal energy, and the soup will decrease in thermal energy. Reason: Thermal energy is the total of all the kinetic and potential energy of the atoms in an object. When the thermal energy of a substance increases, its particles move faster. If the thermal energy of a solid increases enough, it melts into a liquid. The liquid state of a substance always has a higher thermal energy than its solid state. If the liquid continues to gain thermal energy, its particles speed up more. When the particles of a liquid have absorbed enough energy to escape the forces between them, the liquid becomes a gas. The substance has undergone another phase change. As the total kinetic energy of the particles in an object increases, the object gets warmer. Heat flows from a warmer object to a cooler one.

What occures when particles in a gas lose enough thermal energy to form a liquid?
condensation
What are two ways to change the state of a substance?
Substances can change state, usually when they are heated or cooled. For example, liquid water turns into steam when it is heated enough, and it turns into ice when it is cooled enough. The closeness, arrangement and motion of the particles in a substance change when it changes state.
When a liquid becomes a solid where does the heat energy in the liquid go?
A gas has more heat energy, often called thermal energy, than a liquid, even if both the liquid and gas are at the same temperature. Consider that the gas molecules have more thermal energy than liquid molecules of that same substance. The gas molecules are "free" to move around more because they have more kinetic energy than molecules of the liquid. And kinetic energy is function of thermal energy. If we consider the case of water molecules to illustrate our point, when a pan of water is boiling, the water molecules escaping the pan as a gas have more kinetic energy than the ones making up the liquid water that is still in the pan. Also consider the case of water that is evaporating. Wet your finger and blow on it. The liquid water on your finger cools as the evaporating water molecules take thermal energy from that liquid to make their change of state possible. It takes an increase of thermal (heat) energy to change a liquid into a gas.
What has to be added to change one state of matter to another?
heatMost often: energyRemove energy from a gas and it usually liquefies, remove energy from a liquid and it usually solidifies.These changes of phase always occur with a change of heat. Heat, which is energy, either comes into the material during a change of phase or heat comes out of the material during this change. However, although the heat content of the material changes, the temperature does not.
Does condensation take place when the particles of a gas lose enough thermal energy to form a liquid?
yes
