You are driving west in your car on a clear, warm day. up ahead, you see a dark band of ominous clouds. soon, you drive beneath the towering bank of clouds, and things get very dark. for twenty minutes, you are pelted with rain and even some hail. you keep driving west, even though it seems a little sketchy at times. on the radio, you hear that the next county to the north is under a tornado warning. then the sky lightens, and there is only a little rain. you notice that the temperature outside has dropped by 15°f (8°c). what have you just driven across?

the entire statement is true and correct.  

there's no diagram, nothing is illustrated, and no question is asked.

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is

conservation of mass

mass before something happens = mass afterwards
