explain why the tire pressure gauge is turning on and off depending on the time of day susan is driving her vehicle and explain the implications for airing up her tires proberly. in the future then usa a model to show the relationship between temperature pressure volume and the number of moles in relation to the gas laws

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.
