Question

if a pressure of 70.kPa on a volume of 80.cm cubed is reduced to 10.kPa, by what factor does the pressure change

Answer 1

The pressure changes by a factor of 7.

Step-by-step explanation:

In this question, the pressure is reduced from 70.kPa to 10.kPa. To find the factor by which the pressure changes, we divide the original pressure by the final pressure. So, the factor of pressure change is:

Factor = Original Pressure / Final Pressure

Factor = 70.kPa / 10.kPa

Factor = 7

Therefore, the pressure changes by a factor of 7.

Answer 2

70-10/70 x 100 percentage change ....

60/70, 6/7 fract change
