UNIVERSITI TEKNIKAL MALAYSIA MELAKA FAKULTI KEJURUTERAAN MEKANIKAL BMCG 2713 – THERMODYNAMICS TUTORIAL 1 BASIC CONCEPTS OF THERMODYNAMICS 1. What is the difference between intensive and extensive properties? 2. Define the isothermal, isobaric, and isochoric processes. 3. What is the difference between gage pressure and absolute pressure? 4. Most of the energy generated in the engine car is rejected to the air by the radiator through the circulating water. Should the radiator be analyzed as a closed system or and open system? Explain. 5. A vacuum gage connected to a tank reads 30 kPa at a location where the barometric reading is 755 mm Hg. Determine the absolute pressure in the tank. Take Hg = 13590 kg/m 3 . 6. The barometer of a mountain hiker read 930 mbar at the beginning of a hiking trip and 780 mbar at the end. Neglecting the effect of altitude on local gravitational acceleration, determine the vertical distance climbed. Assume an average air density of 1.20 kg/m 3 and take g=9.7 m/s 2 .

###### "Before using Course Hero my grade was at 78%. By the end of the semester my grade was at 90%. I could not have done it without all the class material I found."

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
