Hi -

Grateful for your advice on the question below please ? - I think the question itself is 'flawed', (how can gradient be measured like this ?), but have an answer - curious to see what an expert thinks !

Many Thanks

In an experiment carried out on a fixed amount of gas held at constant volume, the pressure (in units of Pa) was measured as a function of the temperature (*C). pressure / 10- Pa 2.07 1.5 1.0- 0.5 0.0+ 20 40 60 80 100 120 140 temperature / "C Calculate the gradient of the resulting graph to two significant figures, expressing your answer in scientific notation. gradient = Pa"C
