The relationship between pressure and temperature of a kno4rx4d9o8xr tw :jnk6z- 4bciyzv;s +own volume an x-1h:suz 1fu3jv4 evvlxu,v0d amount of gas can be described using Gay-Lussac’sxuf1h v1 uv43l, suzvexj:- 0v law which states that pressure is directly proportional to temperature.P∝T
Where P is pressure in Pa, and T is temperature in K.
1.On the axes above, sketch the graph of P∝T.
2.State two features that would need to be added to your sketched graph to turn it into a drawn graph.
3.The proportionality can be shown in an equation by incorporating a constant, k. The equation becomes P=kT, and follows the format of the equation of a straight line.
3.1.State the feature of a straight line that k represents in this context.
The feature is .
3.2.Deduce the y-intercept of the straight line.
it is (Pa).
