What would be the pressure (in atmospheres) exerted by 0.75 moles of an ideal gas, if the gas filled a 40.5 liter container at a temperature of 19 degrees celsius? (the ideal gas constant is 0.0821 l•atm/mol•k.)

The photo above shows oil and vinegar in a pitcher. the top make a claim about about the density of the vinegar compared to the density of the oil summarize the evidence to support the claim and explain your reasoning

Along wire of diameter 1 mm is submerged in an oil bath of temperature ∞ 31°c. the wire has an electrical resistance per unit length of 0.01 ω/m. if a current of 103 a flows through the wire and the convection coefficient is 500 w/m2·k, what is the steady-state temperature of the wire? from the time the current is applied, how long does it take for the wire to reach a temperature that is within 1°c of the steady-state value? the properties of the wire are 8000 kg/m3, 500 j/kg·k, and 20 w/m·k.

When flexing to a reflective style, one should be specific, brief and to the point, and maintain a fast and decisive pace?
