Why black colour absorb and radiate more heat?
The objects is black when no light reflect from it, hence, it absorb light very well. And at the same time, what can absorb light very well would radiate heat very well .
When sweat evaporates and the the water molecules absorb heat energy why is this important?
they absorb your heat off your skin to keep you cool.
Why is a metal plate used in heat sinks?
because metal is a good conductor of energy (there are a lot of free electrons in a metal) and this will cause the metal to absorb and radiate more energy combined with the increased surface area of the heat sink
Why do rough surfaces absorb and radiate heat fast?
Due to their greater surface area.
Does the Bunsen burner absorb energy as heat?
The Bunsen burner release energy as heat of combustion.

Wavelenghts at which planets emit enregy?
Most planets absorb energy in the light and UV (and shorter) wavelengths. Planets radiate energy in the infrared (heat) and longer wavelengths.
When sweat evaporates and the the water molecules absorb heat energy why is this important?
they absorb your heat off your skin to keep you cool.
How do water and land surfaces differ in their abilities to absorb and radiated heat energy?
Land absorbs more heat energy than water does.

Why do rough surfaces absorb and radiate heat fast?
Due to their greater surface area.
In terms of energy why is water used in cooling systems?
Water has a height specific heat, meaning it can absorb a lot of heat energy per kilogram.
Which method of heat transfer can take place if two objects at different temperatures are placed without touching each other in a vacuum?
Heat doesn't travel through a vacuum. The energy could be changed to light and radiate across the gap, so that would be radiation.
How would greenhouse gases retain energy in the atmosphere?
Greenhouse Gases (water, carbon dioxide, methane, SF6 etc.) are made up of at least two molecules. The bond size between the atoms in the molecules is such that it can absorb heat more easily than other molecules. When solar energy comes to the atmosphere they absorb the solar energy as heat then radiate it to other atmospheric (non-greenhouse) gases such as nitrogen and oxygen..
How does the solar heater heats up the water in the tank?
The solar panels absorb energy from then sun, the solar energy is then transformed into heat energy causing the water to heat up.
Why does the moon have extreme heat and extreme cold?
it has no atmosphere to distribute heat and no water to absorb and release heat. he earth's relatively consistent temperatures are caused by the fact that 70% of its surface is water, which absorbs large quantities of solar energy and releases it slowly back into the atmosphere as heat, while the atmosphere retains and distributes that heat. on the moon, rocks on the sun side absorb heat, becoming very hot, but as soon as they rotate into shadow they quickly radiate that heat into space and become very cold.
What kind of energy do you have when your in a black shirt and start to sweat?
Heat - generated by your metabolism. The colour of your clothes is not important save that a black shirt will radiate heat from you more easily than a white one, but will absorb more external heat such as from the Sun.
