What terms describe the amount of electrical energy used in a certain amount of time?
kilowatthours
What happened to energy when an appliances is used for a longer time?
Typically, an electrical appliance uses electrical energy at a certain rate (a certain power, a certain amount of energy per second). The longer you keep it on, the more energy it will use in total. The relation is simply: energy = power x time Units might be joule, watt, and seconds; or kWh, kW, and seconds.
How does energy conversion support the Law of Conservation?
Any time there is an energy conversion, a certain amount of one type of energy gets reduced, and another type of energy increases. The amounts lost and gained are the same, so total energy is conserved.
Is power related to time or weight?
Power is a measure of the amount of work done in a certain amount of time.
What does mechanical energy transform to?
A body with mass in motion possesses kinetic energy. If it is subject to friction, either on a rough surface or through the air, some of this energy will be converted to thermal energy, ie it will heat up. An extreme example of this is the re-entry of space vehicles into the atmosphere. It could also be converted to potential energy, such as when you fire a bullet upwards, it eventually stops rising, partly because of friction but also because it is being pulled back by gravity.
Efficiency of a machine is?
The amount of energy used in a certain amount of time and the expense.

Why is Hydroelectricity not worldwide?
availability is not everywhere. it can only produce a certain amount of energy at a time

How much energy does uranium produce in a certain amount of time?
The energy produced by natural radioactive disintegration is small an important only at geological times scale.
Are there fridges that automatically close after a certain amount of time?
No, there are not any fridges that will automatically close after a certain amount of time.
What is the amount of goods produced in a certain time?
the amount of goods produced at a certain time is called productivity
What will happen if you get too much carbohydrate?
if your body doesnt use up the energy within a certain amount of time it is stored in lipids(fats)
What is a deposit that gives a certain amount of interest in a specified amount of time?
time deposit
