What two energy transformations happen when you rub two sticks together and fire is started?
When you rub the sticks together, you convert kinetic energy (from moving the sticks) to internal energy, or heat energy - the sticks will warm up. When the heat energy is sufficient to overcome the activation energy of the combustion (activation energy = minimum amount of energy required to start a chemical reaction), the chemical energy in the sticks/whatever you are combusting is converted to heat and light energy
What facts affect seed germination?
Heat, moisture, and airflow. Some seeds also need light to germinate.
What factors affect heat storing of materials?
heat capacity and mass
What is the source of heat and light for all the plants?
The sun is the source of heat and light for plant-life.
What is the source of darkness and cold since the sun is the source of heat and light?
We're modestly familiar with the source of heat and light. And we know that heat and light both exist and are real. Cold and darkness do not exist. They merely describe the lack of heat and light, respectively.
Does the place where the light bulb is affect the heat given off?
does the vessel where the light bulb is placed affect the heat
Are glow sticks exothermic or endothermic glow sticks?
Glow sticks are exothermic.Exothermic is when heat/energy is released. And that is exactly what glow sticks do. but the energy being released is in the form of light.
Why do glow sticks emit light?
Glow sticks emit light through a chemical reaction called chemiluminescence. Inside the stick, two chemicals are mixed together, causing them to react and produce light without generating heat. This reaction creates the glowing effect that we see in glow sticks.
Does colour affect heat or light reflection and retention?
Yes, color can affect heat and light reflection and retention. Light-colored surfaces tend to reflect more heat and light compared to dark-colored surfaces, which absorb more heat and light. This is why wearing light-colored clothing in hot weather can help keep you cooler.
What energy was given off by the buring match sticks?
Mainly heat. Also, to a lesser degree, light and sound.

How does light affect the generation of heat?
Light affects the generation of heat by transferring energy to objects it comes into contact with. When light is absorbed by an object, it causes the object's molecules to vibrate, which generates heat. The more light absorbed, the more heat is produced.
Does light affect absorbstion?
yes it does because light is heat so it will also dry faster
Do glow sticks produce heat?
Glow sticks do not produce heat as they operate through a chemical reaction, rather than a heat-producing process like combustion. The reaction involves a chemical compound inside the stick being mixed with a separate chemical compound, which produces light without generating heat.
What are some charactaristics from the sun that have affect on earth?
Light, heat, radiation
Do curtain colours affect heat and light reflection or attention?
Yes, it does.
How does presence of light affect the rate of decomposition?
light will produces heat which will speed up the rate of decomposition.
