How do you get the energy released when 150 grams of water freezes?
You need to get the energy OUT of the water; otherwise it won't freeze. This is usually done by putting the water in contact with something colder.
Do radios need energy?
Yes, Radios Need Energy. ( All Electronics Need Energy )
Is there any form of energy that is not reversible by itself?
I am not entirely sure what you mean by "reversible by itself".An energy transformation is usually NOT entirely reversible. Some energy is wasted in the transformation, and (even though the energy is definitely still somewhere), you may need ADDITIONAL energy to transform it back.
Why is there a need for energy to be converted form one form to another?
First of all, energy conversions will happen in nature, whether we desire it or not.In technology, different kinds of energy is usually converted to electricity to make it easy to transport. At the other end, the electricity is converted to whatever you need; sound in a radio, heat in a heater, kinetic energy in different machines.First of all, energy conversions will happen in nature, whether we desire it or not.In technology, different kinds of energy is usually converted to electricity to make it easy to transport.

Why you need energy when you sleep?
Because you move a lot when you sleep, To move you need energy so you need energy to sleep.
How much energy do catalysts need?
Usually none.
Why it is important that energy is being transformed?
Usually we need energy in some specific form, so we need to transform it from one type of energy to another.
Why do people need to get used to technology?
Because it keeps advancing.
Does energy need to be converted before it can be used in a technological system?
Yes, usually.
What is terminal decline phenomenon?
i need this answer too
How many electrons does an atom usually need in its outer energy level to be stable?
2.
What do cells need to respire?
It depends what type of cells. Usually it's water and energy but others need sunlight for instance.
Why do you need to conserve your electrical energy?
Saving energy will (a) save you money, and (b) help protect the planet, since using a lot of energy usually harms the planet.
Why a person's metabolic rate naturally decline with age?
The metabolic rate begins to decline at age 30.
Can you decline any portion or all of a loan you do not need?
A. True
Why do cars need fuel?
Fuel is material which is processed (usually 'burnt') to produce energy - heat or power. To move a car takes energy - and that has to be supplied by the fuel.
When are superconductive materials usually most effective?
Superconductive materials are usually most effective when you need to conduct energy. These materials aren't recommended when you are working with water.
