Heat is the energy an object has because of the movement of its atoms and molecules which are continuously jiggling and moving around, hitting each other and other objects. When we add energy to an object, its atoms and molecules move faster increasing its energy of motion or heat.

But surely if moonlight was redirected sunlight it'd be warmer than cooler?

magnifying it would only magnify the beam

making it hotter surely

moon isn't that reflective hence the drop in temperature given off

I tried one of them. It did not seem to work well. Even then is the warmth just going into the sky more where the moonlight can hit.

The answer is that the Moon is actually not very reflective,the Sun is just very bright. The Moon reflects only about 11% of the sunlight that hits it. But the Sun is so bright that even this much reflection looks very bright to us.

The one I used not very good.

night is always colder cos we aren't facing the sun

@carlito the argument is that it probably isn't i think

it'd be different than sunlight

I remember reading that the ground is colder when exposed to clear sky because heat radiates outward with nothing to insulate it. Objects sheltered under something would be slightly warmer as they are partially insulated. For example, the ground under a bridge would have the bridge to retain a bit of its heat at night.

The sun has warmed the surface during the day. Once the sun goes down, the earth's surface will begin to cool (energy emitted is greater than energy received). This causes the earth's surface to become progressively cooler during the night. ... The sun gradually warms the surface throughout the day.

Yes but from melting rocks to no warmth at all. That is not 90% reduction in heat.

yeah

but ur not facing directly at the sun tho

so it will be alot colder

I'm very close to writing an essay on what's going on here

haha

@Drewski4343 yes but that's different than just moonlight and nothing else cooling things down

The magnifying lens is most likely the best test. And moonlight does not produce any heat.

what do you mean, raspberry?

There are like 3 common things I see and I may just decide to write about it

moonlight is just light

@mineyful i've read what you've said but they don't seem to explain the thing

all light is just made from photons, so there is no cold light

Moonlight consists of mostly sunlight reflected from the parts of the Moon's surface where the Sun's light strikes.

yeah you guys keep talking but they don't

@Drewski4343 temperatures can be different in different buildings or in different settings. but you could just cover/uncover a stream of moonlight onto ao thermometer

Most of us use the word 'heat' to mean something that feels warm, but science defines heat as the flow of energy from a warm object to a cooler object.

True but photons can do different things. They shine a laser into the remaining air in a vacuum chamber to make it colder. So light can be used to cool.

Light can be used as the heat source, but the cooling power is not very strong. Much better performance is obtained when laser light is used to cool clouds of atoms and other small objects to near absolute zero.

steve's got a point

only if the material gives of more light than taken in

yees, photons can absorb energy. they are part of the electromagnetic quantum wave

Photons are actually a particle representing a quantum of light or other electromagnetic radiation. A photon carries energy proportional to the radiation frequency but has zero rest mass.

@raspberry so, covering the ground directly after measuring it uncovered has a warmer temperature?

nice explanation

So Moonlight could be absorbing energy. Cooling us.

@Drewski4343 covering/uncovering moonlight. but not insulating the ground. like, a piece of dark paper 20 feet above a thermometer will not insulate it
