When a car burns gasoline, much of the energy is released in the form of heat. which of the following best describes this process in relation to the first law of thermodynamics?
a. energy is not created nor destroyed, but it can change into matter.
b. energy is not created nor destroyed, but it can change from one energy form to another.
c. energy can be created from matter or used to produce matter.
d. some useful energy is lost as heat whenever an energy transfer occurs.
e. energy transfers are always 100% efficient in changing energy from one useful form to another.

Option (B) is correct.

The first law of thermodynamics is an adaptation of the law of conservation of energy, this is thoroughly adapted for the systems(thermodynamics). Law of conservation of energy defines that the total energy of a confined system is stable; energy can be transferred or converted from one form to another, but it cannot be formed or destroyed.

sleep paralysis is a parasomnia, events associated with sleep.

sleep paralysis happens when you are in the middle of waking up or falling asleep. it is the feeling of being conscious but unable to move. it definitely involves hallucinations.

i had a friend that had sleep paralysis and he told me a story one time where he was laying in bed and he couldn't move his body no matter how hard he tried and there was someone standing in the corner of his room coming towards him. he couldn't move and you can't "wake up" because you are already conscious. sometimes sleep paralysis can be triggered by frequent waking up during the night based off of multiple trips to the bathroom, or if you had ever been abused, sleep paralysis can start happening from things like that.
