What is true about models in science?
a. models are accurate enough for the phenomena they represent
b. models only present macroscopic versions of the submicroscopic
c. models explain phenomena but are not good for predicting events
d. models are used throughout science although they are not always accurate

Models are used throughout science although they are not always accurate is true about models in science.

Option D

Explanation:

Models are used in all scientific fields to demonstrate a complex situation or topic easily to the audience. These are made by assumptions taken after observing the behaviour of small amount of sample or data.

We can predict the future mechanism of the sample when subjected to different conditions or situations based on it. But the predictions may or may not be accurate. If the counter research based on the model is not true then the model will be termed as failure.

For example, the plum pudding model of atom proposed by J.J. Thomson was proved wrong after Rutherford found different predictions from Gold Foil experiment. So, models used throughout science although not always accurate.

they are made of gases.

they have a spherical shape.

they make energy through fusion.

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
