An increase in thermal energy gives particles more kinetic energy, which causes them to vibrate more. As they vibrate more, the volume they take up increases.
For example, when ice water is heated up, the molecules spread out, take up a greater space, and so the result is liquid H2O.
The reverse scenario - when gaseous water ('steam') is cooled, due to a reduced level of thermal energy - is that the particles will vibrate less and the substance will contract. The steam will condense into liquid water.

What causes some mechanical energy to change to thermal energy?
Normally, friction between moving surfaces causes mechanical energy to convert to thermal energy (heat), as in the brakes of most cars.
Does thermal energy increase during a phase change?
Thermal energy may increase or decrease during a phase change. It depends on which "direction" the change is going. In a phase change between a solid and liquid, as in the case of water, the solid water (ice) will reach 0 °C by absorbing thermal energy. It's temperature will be rising as it absorbs heat. But at the transition temperature, it must still absorb some heat to "make the transition" from ice at 0 °C to water a 0 °C. This thermal energy is the enthalpy of fusion. Thermal energy will have increased during the phase change. Another way make the point is that water at 0 °C will have more thermal energy than an equal mass of ice at 0 °C. If you guessed that the opposite is true, you'd be correct. The changes in thermal energy apply to "regular" phase changes between solids, liquids and gases. (There are other types of phase change that don't involve thermal energy or the change of state from solid, liquid or gas.) A link can be found to the enthalpy of fusion for you to investigate further into this one type of transition. That link is below.
What are examples of single energy transformations?
1. when a toaster transforms electrical energy to thermal energu to toast your bread. 2. a cell phone transforms the electrical energy to eletromagnetic energy to contact with other cellphones. hope you understand it:)
Examples of reversible physical change?
examples of physical change are ice,water,chocolate,liquid,
The addition or loss of thermal energy changes the arrangement of the particles during what?
a change of state
Explain how a change in thermal energy causes matter to change from one state to another. Give two examples?
It causes matter to change by turning water into gas which is vaporization. water into ice and burning wood into ash.
How does change in thermal energy causes matter to change from one state to another?
An increase in thermal energy may change a solid to a liquid, a liquid to a gas, or a solid to a gas.A decrease in thermal energy may cause a change in the opposite direction - for example, from a liquid to a solid.
How does a change on thermal energy cause matter to change from one state to another?
It causes matter to change by turning the water into gas which is vaporization, turning water into ice.
What is another chemical change?
Thermal decomposition is a chemical change.

What is meant by the term chemical change Give 2 examples?
A chemical change is a change that imply the change of the nature of molecules. Examples: neutralization of an acidic solution, thermal decomposition and generally all chemical reactions.
How does in thermal energy cause matter to change from one state to another?
An increase in thermal energy may change a solid to a liquid, a liquid to a gas, or a solid to a gas.A decrease in thermal energy may cause a change in the opposite direction - for example, from a liquid to a solid.
When you put on the brakes of a bicycle friction causes some of the mechanical energy of the brakes to change to thermal energy?
true
What causes some mechanical energy to change to thermal energy?
Normally, friction between moving surfaces causes mechanical energy to convert to thermal energy (heat), as in the brakes of most cars.
What is heat strain?
heat strain or the thermal strain is caused due to the temperature changes. A solid body expands as the temperature increases and contracts as the temperature decreases.this causes the thermal strain. for a homogeneous and isotropic body the thermal strain is caused by change in temperature. thermal strain = coefficient of linear thermal expansion * change in temperature where the coefficient of linear thermal expansion gives the strain per degree of temperature.
How Does Thermal Energy Cause Change?
An increase in thermal energy gives particles more kinetic energy, which causes them to vibrate more. As they vibrate more, the volume they take up increases.
How a change in thermal energy causes matter?
A burning wood fire, when cooled down or extinguished, leaves wood ashes.
