How a change in thermal energy causes matter to change from one state to another give two examples?
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 else can I help you with?
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 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:)
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.
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
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.
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.
What is another chemical change?
Thermal decomposition is a chemical change.

What are some non examples of thermal expansion?
Some non-examples of thermal expansion would include the boiling of water, which involves a phase change rather than expansion due to temperature increase, and the stretching of a rubber band, which is a different mechanism of deformation unrelated to temperature change. Additionally, the growth of a plant is not an example of thermal expansion.
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.
Can energy change to one anothere?
Yes, for instance potential energy can change into kientic energy and electromagnetic raditaion energy can change into thermal or chemical energy. It is also possible to change matter into energy and energy into matter.
What energy causes of state in a system?
The energy that causes a change of state in a system is typically thermal energy. When thermal energy is added or removed from a system, it can cause the particles within the system to gain or lose kinetic energy, leading to a change in the state of matter (such as melting, freezing, boiling, or condensation).
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.
How a change in thermal energy causes matter?
A burning wood fire, when cooled down or extinguished, leaves wood ashes.
What has thermal energy moving from one substance to another?
The transfer of thermal energy from one substance to another is called heat transfer. Heat can transfer through conduction (direct contact), convection (through fluids), or radiation (electromagnetic waves). This transfer of heat causes a change in temperature in the substances involved.
