A Pyrex beaker is filled to the brim with 250 ml of glycerin at 15°C. How much glycerin overflows at 25°C?

Two large tanks, each holding 100L of liquid, are interconnected by pipes, with the liquid flowing from tank A into tank B at a rate of 3L/min and from B into A at a rate of 1L/min. The liquid inside each tank is kept well stirred. A brine solution with a concentration of 0.1kg/L of salt flows into tank A at a rate of 6L/min. The (diluted) solution flows out of the system from tank A at 4L/min and from tank B at 2L/min. If initially, tank A contains pure water and tank B contains 10kg of salt, determine the mass of salt in each tank at time t≥0. What is the solution to the system? x(t)=                                     y(t)=

A car tire has an inner radius of 45.46 cm has a low pressure of 195 kPa. The tire is recommended to be inflated to 248 kPa. At the low pressure the tire outer radius is 56.65 cm and fully inflated is 67.81 cm. The outside temperature is 17 0C. What is the mass of the air to inflate the tire? How many air molecules are added to properly inflate the tire?

What is the density of water vapor in the air on a hot, dry day in the desert when the temperature is 40.0 °C and the relative humidity is 5.00 %? The vapor pressure of water at 40.0 °C is Py = 7.34 x 10° Pa and the molecular mass of water is M = 18.0 g/mol. Enter your answer in units of grams per cubic meter. density: g/m3
