A rigid cylinder with a movable piston contains a sample of hydrogen gas. At 320. K, this sample has a pressure of 160. kPa and a volume of 3.85 L. What is the volume of this sample at STP? (Make sure you round your answer to the correct number of significant figures) *

answer: semi-infinite solid initially at a uniform temperature of 400 ◦c is cooled at its surface by convection. the cooling fluid at a constant temperature of 200 ◦c has a convective coefficient (ha) of 250 w/m2.k. the physical properties of the solid: k = 20 w/m.k and α = 4 * 10-5  m2/s. using δx = 0.04 m and δt = 10 s. write the finite difference equations describing the transient heat transfer of the first five δx and the temperature profile after 30 s.
