Physics 7 B Midterm Review Gabriel Wong1. In place of pressure and volume, we can use Temperature and Entropy to specify thestate of a gas. Plot the Carnot cycle on the T- S plane. a.) What does the area inside the curve representb.) What region of the T-S plane corresponding to the heat input?c.) Based on a.) and b.) , explain why the Carnot engine achieves the maximumefficiency of any reversible engine2. A gas of N particles has a velocity distribution given by f(v) = C v^2 for v smallerthan 10 m/s and f (v) = 0 for v bigger than 10 m/s.a.) Find the mean speed of the particles b.) Find the rms speed of the particles3. An air bubble of volume V forms at the bottom of a lake of depth 30 m. Suppose thewater pressure at the bottom of the lake is 1.5 atm and the Temperature is 4 C.
