What are some examples of chemical to electrical energy?
ex: mechanical energy * a running person * moving windmill * person throwing a ball ex: electrical energy * t.v * computer * toaster
How is energy involved in a chemical changes and physical changes?
Energy can be absorbed or released in a chemical or physical change, it is not destroyed or created. It simply assumes a different form. This is the law of conservation of energy. Accounting for all the energy present before and after a change is not a simple process. But scientists who have done such experimentation are confident that the total amount of energy remains the same.
Is painting a wall physical change or chemical?
Physical - because you're changing the appearance - not the composition of the wall.
When a person gets hypothermia the enzymes in their body become less active how does this change affect the body's chemical reaction?
most chemical reactions require a certain input of energy, meaning they need to be at a certain temperature. when the temperature is too low or too high, these chemical reactions cant take place.
Is age physical or chemical change?
Aging is a physical change that is brought on by a chemical change. As a person ages, there are hormones that get depleted, like estrogen for women, and testosterone for men. This chemical change in the body leads to a physical change in appearance.
How is energy involved in chemical?
cause energy change chemical. when a person do some vigorous exercise his enery is not lost or not increase but his energy changes from one form to another when a person lift a very big weight he is tired because of his energy canged from one form to another our energy is not destroyed and no increase but its only changed the form.
Is it a physical or chemical change when you use an air pump?
That is a physical change - at least the pump is (air in, air out, with no chemical change). The energy required to run the pump probably will come from a chemical reaction though: an electric generator burning fuel to run the generator or food being digested and converted to energy in the muscles if it is a person powering it
What energy transformations happen when a person lifts a chair?
Chemical energy from the person's muscles is turned into potential energy.
What energy transformation happens when a person lifts a chair?
You are using chemical energy produced in your muscles to lift a weight against gravity, which means the weight gains gravitational potential energy
Which type of energy is converted into mechanical energy when a person walks.?
A person converts chemical potential energy into kinetic/mechanical energy when he walks. The chemical potential energy usually takes the form of adenine triphosphate (ATP) stored in the body.
What form of energy when person running?
Chemical potential energy of the body is converted to kinetic energy.
What form of energy is used when a person is climbing a ladder?
The person will use the energy of his muscles to do that. This energy comes from the food eaten by people.
What is the energy transformation taking place when a person jogs at the park?
Chemical energy is transferred into kinetic energy. When a person jogs, motion is produced.
Is old ham in the refrigerator a chemical change or physical change?
When ham get "old" (ie rots or degrades), it undergoes both a chemical and a physical change. Microbes break down the meat into energy they can use and in turn leave their metabolic wastes (ie a biochemical change). When a person notices a ham after it has been sitting on a shelf for several week, that person will notice that the color, shape, smell, and taste (if they are brave) of the ham has changed. Thus the changes are both chemical and physical
Is Ag a physical or chemical change?
Aging is a physical change that is brought on by a chemical change. As a person ages, there are hormones that get depleted, like estrogen for women, and testosterone for men. This chemical change in the body leads to a physical change in appearance.
What form of potential energy does a person blowing a vuvuzela have?
chemical potential energy
What is the process in which radiant energy from the sun is converted into chemical energy?
I have no idea=please ask another person=
