Question

MATLAB language;

...

Boyle's law of gases says that:

P1V1 = P2V2

Make a program (script) that calculates any of the 4 parameters, based on the elements that the user decides, that is:

P1 = P2V2 / V1 - ask for the data that is needed. P2, V2, V1

V1 = P2V2 / P1 - ask for the data that is needed. P2, V2, P1

P2 = P1V1 / V2 - ask for the data that is needed. P1, V2, V1

V2 = P1V1 / P2 - ask for the data that is needed. P1, P2, V1

REMEMBER THAT FROM THAT ELECTION, THE REQUIRED VALUES ARE ASKED

Answer 1

%{
MATLAB script to calculate the desired parameter value out of four (P1, V2, P2, V2)
based on the values entered for other parameters
%}

fprintf("Enter parameter values below and leave the unknown parameter blank to calculate its value.\n");

P1 = input("Enter value of P1: ");
P2 = input("Enter value of P2: ");
V1 = input("Enter value of V1: ");
V2 = input("Enter value of V2: ");

if(isempty(P1))
if( isempty(P2) || isempty(V1) || isempty(V2) )
fprintf("Enter atleast any 3 parameters to calculate value of remaining one\n");
else
P1 = P2 * V2 / V1;
fprintf("P1 = %f\n",P1);
