Substance that provides energy as the result of a chemical change?
Fuel. :)
A substance that provides energy as a result of a chemical change is a?
Fuels
What is different between exothermic and endothermic reactions?
If energy is released as a result of a process, an exothermic change has taken place. If a constant input of energy is required to drive a physical or chemical change, the change is described as endothermic.
Why is the enthalpy change of combustion for methanol less negative than methane?
The combustion of methanol to form products of H2O and CO2 do not have as much of an energy change compared to methane and a result methanol releases less energy compared to methane. The more negative an enthalpy change is, the more heat it is going to release.
What is the end result in a chemical change?
The end result in a chemical change is an atom
Can you make thermal energy?
No. The law of conservation of energy states that energy can not be created or destroyed. However, energy transfers can result in thermal energy.
Which type of energy is stored energy as a result of a change in position or condition?
pontential energy
Which type of energy is stored as a result of a change in position or condition?
Potential Energy (change of position) and latent energy (change of state condition as freezing)

What is a type of energy resource?
Substances in Biology that provide energy as the result of a chemical change are called?
What term is defined as energy stored in an object as result of a change in its position?
That is called potential energy.
Explain how the energy from the sun travels from the sun and allows us to feels its warmth on your face?
The energy travels from the sun through the form of radiation. We feel the UV part of that radiation, which transfers it's energy to our skin cells, which heat up as a result.
A substance that provides a form of energy such as heat as a result of a chemical change?
Iron
Which type of energy as a result of a change in position or condition?
This form of energy results from the fact that there is the potential for the wrecking ball to do work.
What does alcohol in a thermometer rise in a result of?
The heat on the outside of the thermometer transfers to the glass which transfers to the alcohol making the alcohol expand making it rise
Where does the energy go since heat of vaporization does not result in a temperature change?
It increases the potential energy of the molecules, since they separate from each other.
