The following figure shows a manometer filling with mercury connected to a tank filling with a liquid and gas methane. Calculate the gas pressure, in cm Hg and Pa. (Density of mercury =13.6×10³kgm¯³). (atmospheric pressure =76Hg) (g=10N kg ¯¹)​

Which process is represented by the pv diagram? a. the isobaric process b. the isovolumetric process c. the isothermal process d. the adiabatic process

Could someone me find the answer to this problem.

Consider a 1000 w iron whose base plate is made of 0.5 cm thick aluminum alloy 2024-t6 (ρ = 2770 kg/m3 and cp = 875 j/kg°c). the base plate has a surface area of 0.03 m2. initially, the iron is in thermal equilibrium with the ambient air at 22°c. assuming 90% of the heat generated in the resistance wires is transferred to the plate, determine the minimum time needed for the plate temperature to reach 200°c.
