Answer:
exothermic
Explanation:
An exothermic reaction is a chemical reaction that releases energy through light or heat. It is the opposite of an endothermic reaction. Expressed in a chemical equation: reactants → products + energy.
Explanation :
The spherical mirrors are of two types i.e. concave mirror and the convex mirror.
The mirror whose reflecting surface bulges inwards are called concave mirrors. It is also known as converging mirror. Th attached figure shows a concave mirror.
The image formed by concave mirror is real inverted. There is only one case when the formed image is virtual and erect when the object is placed in between the pole and the focus.
The loss or conservation of kinetic energy is the difference between an elastic and an inelastic collision. Kinetic energy is not preserved in an inelastic collision, and it will change forms into sound, heat, radiation, or another form. The kinetic energy in an elastic collision is preserved and does not change forms.
It gets converted from one form to other forms.
The great thing about the incandescent light bulb ... the original kind,
invented by Thomas Edison ... is that it can take electrical energy and
instantly turn it into light energy and heat energy. So you can use the
bulbs in your house to see at night without burning candles or oil, and
you can even use them in your chicken coop to keep the chickens warm.
I used one a few years ago when I found a tiny abandoned baby possum under the bush in my front yard. The poor thing was almost frozen. I put
it in a box with a few of my old T-shirts, and put an incandescent light bulb
under the box to keep it warm. In the morning, I took it to a wildlife rescue place on the lake-shore here in Chicago. They told me that the baby would
not have survived without the heat overnight. And three months later, they
sent me an email saying that my baby possum had grown big and strong,
and that they took him to the forest preserve and released him in the wild.
That was a rare occasion. We don't actually use light bulbs for heat too
much any more, so it's considered wasted energy in light bulbs. We have
better ways to generate heat now, and for light, we're changing to devices
that run cool and make a lot more light with the same amount of electrical
energy ... like fluorescent tubes, CFL curly bulbs, and LED bulbs. The
incandescent bulb is going away.
But the principal is still the same ... convert electrical energy into light energy.
