Question #1: Find the state of a closed system containing water substance of given mass as mentioned in the table below. Specify the zone in which the point lies and properties v, u, h and s as appropriate. Also comment on the approximated value if applicable Q # Mass [kg] 1 1 2 2 3 1 Property 1 P= 100bar P=15MPa T=170°C Property 2 T=250°C Saturated vapour H=2816.2kJ

An object is placed against the center of a spherical mirror and then moved 80An ideal gas at 14.7 °C and a pressure of 2.92 x 105 Pa occupies a volume of 3.40 m?. (a) How many moles of gas are present? (b) If the volume is raised to 5.33 m and the temperature raised to 31.0 °C, what will be the pressure of the gas? (a) Number Units (b) Number Units cm from it along the central axis as the image distance i is measured. The figure gives i versus object distance p out to ps 46 cm. What is the image distance when the object is on the central axis and 76 cm from the mirror?

Ethylene glycol (antifreeze) has a density of 1.11 g/cm^3. What is the mass in g of 417 mL of this liquid?

What is the specific? weight of nitrogen in units of new temper cubeter. at the temperature of minus 10 Celsius and the pressure of 0.6 bar gauge ?  Please. I want you to give me details in how you confirm each unit. I don't want answer like I provide. I want another answer with more details. And please, could you use this formula?  Specific Weight (γ)=ρ×g =(P(abslot/Rsp*T)×g

Letters G and H
