State the First and Second Laws of Thermodynamics and explain why they are important in understanding your ability to extract and use energy resources?
The first law states that neither matter nor energy can be created or destroyed The second law states that everything tends toward disorder ie. falls apart, fades, withers, erodes, etc. I like the versions: 1st: You can't get something for nothing 2nd: Not only that, you can't even break even
Is it true fossil fuel's transform chemical energy into another form of energy?
If you mean the use of fossil fuels, yes. Typically, the fuels are burned (for example, in a car engine), converting the chemical energy into heat. Part of this is then converted into movement. A heat engine can only convert part of the heat energy into useful energy, so the remainder is wasted.
Where is useful thermal energy stored?
geothermal energy.....I hope you will pass your grade
When does this chemical energy become useful to you?
Chemical energy in gasoline becomes useful when we run our vehicles. In wood, it becomes useful when we burn it to heat our homes. In foods, it becomes useful when we eat the food.
How is coal converted to the energy people use?
The most useful energy that coal provides is as a fuel for combustion; we have to burn it. Burning coal creats heat we can use to boil water, turning it to steam, and then we use the steam to drive turbines to make electricity.
What is useful and wasted energy?
Useful energy is energy that can be converted to any other type of energy. Wasted energy is no longer available to be converted - usually because it got spread out too much, or because it got converted to heat. Heat can be partially, but not completely, converted to other types of energy.
What percentage of energy is converted into useful energy?
It depends on the efficiency of the machine. No machine is perfect and there are always losses and waste. Usually the losses are a greater percentage than the useful energy.
An airplane changes energy into different forms The total amount of energy does not?
The total amount of energy doesn't change. However, some useful energy will be converted into unusable energy.The total amount of energy doesn't change.

Is nuclear energy potential energy or kinectic energy?
Until converted, it is potential energy. However, to make nuclear energy domestically useful it is converted into thermal (thermodynamic) energy (heat), which, in turn, is converted into electrical energy, both of which are kinetic energy.
Is nuclear energy thermal energy or potential?
Until converted, it is potential energy. However, to make nuclear energy domestically useful it is converted into thermal (thermodynamic) energy (heat), which, in turn, is converted into electrical energy, both of which are kinetic energy.
The percentage of energy from a fuel that is actually used to perform work is its?
That is called efficiency. An efficiency of 1 (or 100%) means that all the energy is converted into useful work.That is called efficiency.

Can some energy is lost during every transfer or conversion.?
Usually some energy is wasted, yes. Energy is not "lost" in the sense of conservation of energy; energy is always conserved. However, useful energy gets converted into unusable energy all the time.
When one type of energy is transformed into another type of energy during a conversion what u is lost?
Total energy is always conserved. What is lost is that usually, some useful energy is converted into unusable energy - for example, heat that is spread out.
Natural gas is a fuel What do you mean by fuel?
By fuel we usually means something that can be burned. The energy released(usually heat) in the burn can be converted to other, more useful forms of energy, like electricity, or mechanical energy(movement).
What are the uses of alternative energy?
The energy itself is used the same way as any other energy - to heat our homes, operate electrical appliances, etc. Once such energy is converted to a useful form - usually electrical energy - it makes no difference (for the ability to use it) where the energy comes from.
What role does friction play in energy transformations?
In many cases, energy is wasted due to friction - meaning that useful energy is converted into unusable energy.
Why do you have to conserve energy when infact the energy of this world is constant?
While the TOTAL amount of energy remains constant, on the other hand, useful energy can, and will, be converted into unusable energy.
