An ideal gas initially at 305 K undergoes an isobaric expansion at 2.50 kPa. The volume increases from 1.00 m3 to 3.00 m3 and 12.8 kJ is transferred to the gas by heat.
(a) What is the change in internal energy of the gas?
kJ
(b) What is the final temperature of the gas?
K
An anemometer for measuring wind speed consists of four metal cups, each of mass m = 140 g, mounted on the ends of four essentially massless rods of length R= 0.37 m. The rods are at right angles to each other and the structure rigidly rotates..
