Question

What is mean by isothermal process??​

Answer 1

Answer:

Let add both equation

5x + 3y = 9

+ 4x - 3y = (-18)

____________

9x = (-9)

:. x = (-1)

put this value in equation 1

\longrightarrow \rm 5x + 3y = 9⟶5x+3y=9

\longrightarrow \rm 5 \times ( - 1) + 3y = 9⟶5×(−1)+3y=9

\longrightarrow \rm ( - 5) + 3y = 9⟶(−5)+3y=9

\longrightarrow \rm 3y = 9 + 5⟶3y=9+5

\longrightarrow \rm 3y = 14⟶3y=14

\begin{gathered} \longrightarrow \blue{\boxed{ \rm y = \frac{14}{3} }}\\ \end{gathered}

⟶

y=

3

14

Answer:

isothermal process is the process with constant temperature

delta T = 0
