List down what life on earth would be like without the light and heat energy from the sun?
Actually light and heat is one of the most important things we get from the sun which fosters life on earth. Without light plants will not carry out photosynthesis and ultimately they will die. Heat keeps our earths temperature warm otherwise the earth will freeze.
What would happen in the central heating system if someone bought two radiators?
Most central heating systems have more than one heat emitter, but as long as there's a rough balance between heat input from the system heat source and the heat emitters, the number of emitters doesn't matter. If you are thinking of adding two radiators to an existing system without changing the amount of space to be heated, if the boiler is adequate now, it still will be. If you are adding them to heat a basement area underneath the area presently heated, this is also generally not a significant change (heat rises). If you're adding a free standing uninsulated 1000sq foot greenhouse, you should consult a heating company in your area.
Why the temperature in earth surface is important?
One of the ways heat flows from the atmosphere to the air is through conduction. Convection is another, and radiation is yet another. Convection is how heat is transferred from earth's hot interior to the mantle. Without these ways of transferring heat, life on earth could not exist.
What are the processes that cause water to change from one state to another?
Through changes in heat energy withing the H20 molecules. When there is more heat, it boils and evaporates into a gas When there is less or almost no heat, it freezes into ice.
How does adding or removing heat to a system result in of temperature or change in state?
then the temperature either goes up or down. When you add heat to a substance the substance normally spreads out more for on a subatomic level the atoms vibrate more. Gases have a larger volume at the same pressure and fluids can increase in volume too. Solids normally expand. The opposite to the above is true with a decrease in temperature. It is good to note that if you melt ice it decreases in volume which is proof that heat dose not always expand the substance.
How can you change matter form one state to another?
By adding heat and removing heat.
How can temperature be increased without heating?
It is possible to add heat to a substance without changing its temperature. That happens during melting and boiling. However, I cannot think of a case in which the temperature of a substance increases without heat being added to it, either by radiation, conduction or convection.

What 2 things can change matter from one state to another?
adding heat or freezing
Under what condition is heat transferred from one object to another?
Heat normally flows from a warm object to a cool object
Why are cats warm blood animals?
A warm-blodded animal is one that produces body heat by its own muscle action. Cats do this, so are then called "warm-blooded".
What is the difference in specefic heat and latent heat?
Specific heat is the heat energy in joules required to rise the temperature of one kg of substance through one kelvin without a change in its state. But latent heat is the heat required to change the state of one kg of substance without change in temperature.
What is the transfer of heat from warm to cold areas called?
If you heat one end of a metal bar then the heat passes along the bar by a process known as conduction.
Does the heat energy pass from molecule to molecule?
yes, if heat didn't pass from one molecule to another, nothing would not be hot or warm.
How does adding or subtracting heat affect temperature?
Adding heat energy usually warms a substance, and subtracting heat energy usually cools the substance. heat energy only moves from a hot substance to a cool substance. Example: a pan on the stove could be room temperature, but once you put it on the flame, the heat from the flame transfers to the cooler pan, heating it up.Additional answerIn some cases adding heat energy does not raise the temperature but moves the substance from one phase to another. For example, if you add heat energy to ice you melt it and it becomes water at the same temperature. If you continue adding heat energy then, of course, that water then gets warmer.
How do the waters of the earths ocean help distribute heat from one place to another?
The heat transfers through the entire ocean, since its technically one big global ocean.
