What else can I help you with?
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.
Give an example of one type of energy conversion?
Mechanical energy is supplied to a generator from an engine, a steam turbine for example, and converted to electrical energy
Give an example of one type of energy conversion change to another form?
Heating food in a microwave: Electromagnetic radiation energy in the form of microwaves cause increased vibration of bonds in water molecules resulting in the increased heat production.
What transfer of energy is and give an example?
Transfer of energy refers to the movement of energy from one system or object to another. This can occur in various forms such as heat, work, or electromagnetic radiation. An example of transfer of energy is when sunlight transfers energy to plants during photosynthesis.
Can you give me one example of an energy transformation?
When a light bulb is turned on, electrical energy is transformed into light and heat energy.

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 is it called when heat causes an object to give off light?
energy
Give an example of nuclear energy?
heavy water
Can you give an edible example of a phase change?
Making ice cream and then letting some of it melt are two examples of phase changes.The extreme cold of the ice cream maker causes the liquid cream to give up its heat and turn solid. This freezing phase change is exothermic because energy (heat) comes out of the cream.If you leave a bowl of ice cream on the table in a warm room, the heat energy of the air will enter into the ice cream and it will become liquid. This melting phase change isendothermic.Memory tip:exo - the heat energy exits the cream, which gets colder.endo - the heat energy goes into the ice cream, which gets warmer.

Why does the shape of mitochondria change?
No, they give the cell energy.
Give one example when magnetic energy changes into electric energy?
A discharging inductance.
What causes light to refract Give an example form everyday life?
Sex

What is the chemical change and kindly give a example or picture?
Chemical change is a process in which reactants are changed to form one or more than one products. During a chemical change there is rearrangement of atoms i.e, breaking and formation of new bonds.This change is not reversible. For Example: # burning of wood # change in temperature or energy,as in exothermic or endothermic reactions. # formation of precipitate in a reaction.
