scientist might model volcanic eruptions using a computer model. what is the biggest benefit of this model a. It can be used to measure the temperature in a volcano b. using a model is less hazardous than studying the volcano close up c. only the lava of the volcano is shown by the model d. it can be used to make animations of volcanic eruptions for movies

the correct answer is answer a. a mixture

no other options make sense

hope this

have a great day : )

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml
