If the pressure, volume, and temperature of a gas are known, which can most likely be found by using the ideal gas law? a. the molar amount of the gas
b. the partial pressure of the gas
c. the standard temperature and pressure
d. the molar mass

catya that's not even a b or c

the answer is symmetrical : )

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.
