C p/jmol-1k-1 =20.17 +0.3665 t/k

calculated q , w, delta h when temp is raised from 25 to 200 °c . at constant pressureq_p and volume q_v. i know how to find w and q but how to find Δ h i dont know what C_p is never heard of it nor is it in my textbook

It helps if you spend some time formatting your post, using appropriate symbols for units, and subscripts/superscripts and capital letters where applicable. Otherwise it's hard to read and understand what you write.  Use of complete sentences would also help immensely.

qp - that is, q_p - is probably the heat transferred under constant pressure conditions.
