80 kg saturated steam at 10 bar, 20 kg ice at -200C , and 100 kg water at 800C are mixed together in an insulated pot. The pressure is kept constant at 10 bar. What is the temperature and phase of the mixture in the pot at equilibrium

Ahuge (essentially infinite) horizontal nonconducting sheet 10.0 cm thick has charge uniformly spread over both faces. the upper face carries +95.0 nc/m2 while the lower face carries -25.0 nc/ m2. what is the magnitude of the electric field at a point within the sheet 2.00 cm below the upper face? (ε0 = 8.85 × 10-12 c2/n · m2)
