What else can I help you with?
Is photosynthesis a physical change?
No, photosynthesis is a chemical change by which water and carbon dioxide are converted into oxygen and carbohydrates.There is an energy transformation. Light energy is converted to chemical energy
What reactions convert light energy to chemical energy?
The light dependent reactions take in the light energy and convert that to chemical energy, but it is in the Calvin cycle (light independent reactions) where the chemical energy is stored in a complex sugar.
What is the energy role of chloroplasts?
They are energy transformers. They convert light energy to chemical energy
Does a light switch change chemical energy directly in to light energy or does a flashlight?
A light switch simply completes a circuit, allowing electrical energy to flow through a light bulb which then produces light energy. In a flashlight, a battery provides electrical energy which is converted into light energy by the bulb or LED.
What is a change of an organism's use energy for growth and repair?
Just 2 of the possible answers:Plants use external energy - light (photo-electric energy) for photosynthesis and make glucose. So in this example light energy --> chemical energyMany living organisms use chemical energy stored in their cells as fat/glucose/starch/ATP for heat and movement. So chemical energy --> thermal energy or chemical energy --> kinetic energy.
What can change light energy to chemical energy?
Plants can change light energy into chemical energy during the process of photosynthesis!
What type of energy change in torchlight?
Torchlight involves a conversion of chemical energy from the batteries into light energy, which is emitted as visible light.
Can electrical energy change into chemical energy and light energy?
Yes, electrical energy can be used to drive chemical reactions in a battery to store energy in the form of chemical energy. Additionally, electrical energy can be converted into light energy by passing an electric current through a light bulb or LED.
Does a flashlight change from chemical energy to light energy?
Yes, a flashlight changes stored chemical energy into light energy when the battery powers the light bulb. The chemical energy in the battery is converted into electrical energy, which then powers the light bulb's filament to produce light.
Where does light energy change into chemical energy in plant cells?
The Chloroplasts
Is photosynthesis is chemical or physical change?
ChemicalCO2 is reduced into glucose. Water is oxidized into Oxygen.Also energy transformation occurs. Light energy transforms into chemical energy
What is it when you change light energy into chemical energy in plants?
That process is known as photosynthesis.
How can mechanical energy change into chemical energy?
Mechanical energy can change into chemical energy through processes like photosynthesis in plants. In this process, light energy is converted into chemical energy stored in the bonds of molecules like glucose.
What is the process when plants change light energy into chemical energy?
Plants use a process called photosynthesis to convert light energy into chemical energy. During photosynthesis, plants absorb light energy, which is used to convert carbon dioxide and water into glucose (sugar) and oxygen. This process occurs in chloroplasts, which contain chlorophyll, the pigment that captures light energy.
What energy change happens in a greenhouse?
Light to heat and chemical energy in plant's biomass
Is production of light by a lamp physicalnor chemicaln change?
The production of light by a lamp is a physical change. It involves the conversion of electrical energy into light energy through a process that does not alter the chemical composition of the materials involved.
In a chemical change energy does what?
In a chemical change, energy is either absorbed or released. This can result in changes in temperature, light production, or other forms of energy transfer during the reaction.
