Chapter 1, Problem 1P

A graduated cylinder was filled with gasoline to 100 ml. Its total mass was 188 g including the 120 g cylinder. If 20 g of gasoline evaporated, what would be the reading on the graduated cylinder? 78.1 86.4 a. 62.2 b. 70.6 C. d.

the question from thermodynamics  Oxygen (molar mass 32 kg/kmol ) expands reversibly in a cylinder behind a piston at a constant pressure of 3 bar. The volume initially is 0.01 m3 and finally is 0.03 m3; the initial temperature is 18.97 0C. Calculate the mass of oxygen with the correct unit to four decimal places. Assume oxygen to be a perfect gas and take the specific heat at constant pressure as =  0 . 9 1 7 k J / k g K and molar gas constant as  =  8,314  J / kmol K

The production data for a well is as follows; 450 bbl/day of water 2800 bbl/day of 34.5o API oil 9.85 mscf/day of gas What is the density of the oil in kg/m3? (Input your answer in the space below to 2 decimal places)

Points: 201 3) Three objects are connected by massless wires over a massless frictionless pulley as shown in the figure. The tension in the wire connecting the 10.0-kg and 15.0-kg objects is measured to be 133 N. M A 15.00 kg 133 N (a) What is the mass M? 10.00 kg (b) What is the acceleration of M? (c) What is the tension in wire A?

A reservoir of oil has a mass of 830 kg. The reservoir has a volume of 0.920 m³. What will be the value of weight density? Select one: 3 O a. 88.50326 KN/m 3 O b. 90.2173 Kg/m 3 O c. 8850.326 N/m O d. 902.173 Kg/m

As of October, 2016 the world's largest pumpkin weighed 1190 kilograms. In order to grow a record-setting pumpkin, the fruit's mass must increase by an average of 18 kg/day. If we assume that the density of raw pumpkin is approximately 0.50g/cm³ we can convert this to an increase in volume of 1.27ft³/day. If the volume of a spherical pumpkin is increasing at 1.27ft³/day, then how fast is the surface area of the pumpkin changing when the diameter of the pumpkin is 7 ft? Give the answer with two decimal places, and include units.
