Question

2.Consider the relationship between the temperature and pressure of a gas, when the volume is held constant. Is the relationship directly proportional or indirectly proportional? 3.Which gas law does this demonstrate?

Answer 1

Explanations:

According to the pressure law, the pressure (P) of a fixed mass of a gas is directly proportional to its absolute temperature (T) provided that the volume remains constant. Mathematically;

`\begin{gathered} P\alpha T \\ P=kT \\ k=(P)/(T) \end{gathered}`

k is the variation constant

If we have initial and final pressure and initial and final temperature, the formula can be written as:

`k=(P_1)/(T_1)=(P_2)/(T_2)_{}_{}`

3) The gas law that demonstrates the equation and definition above is known as the PRESSURE LAW.
