Graph, on a single hs plot, the isotherm for propane at 20°c and the isobar for propane at 1 bar.
use the data to estimate the slopes of each curve at the point where they cross. that is, numerically estimate \left(\frac{\partial h}{\partial s}\right)_t(∂h∂s)t and \left(\frac{\partial h}{\partial s}\right)_p(∂h∂s)p at 20°c, 1 bar.
h=517.6 kj/kg s=2.194 kj/kg-k
in the slides, i stated that \left(\frac{\partial h}{\partial s}\right)_p(∂h∂s)p = t. prove that this is true. compare this value to the answer estimated from the data.
note: i am not asking you to do \left(\frac{\partial h}{\partial s}\right)_t(∂h∂s)t because it is much more difficult than you are expected to be able to do at this stage.

When an experimenter draws a conclusion that he assumes will apply to all situations set up similarly to his test situation, even though he cannot possibly have examined all possible test scenarios, the experimenter is using deductive reasoning inductive reasoning abductive reasoning subjective reasoning
