Question

5 kg steam expands in a piston-cylinder device from a pressure of 5 bar and
700°C (h=3925.97 kJ/kg s=8.5892kJ/kg-K, u=3477.52 kJ/kg) to a pressure and temperature of 3 bar and 600°C(h=3703.20 kJ/kg s=8.5892kJ/kg-K, u=3300.79 kJ/kg ).If the process is reversible and adiabatic, calculate the total work(kJ) for the process

Answer 1

The two types of cells that are capable of changing their shape are:

(i) White blood cells (WBCs):- The white blood cells (leukocytes) present in our blood they have the ability to change their shape. This helps them to kill germs by engulfing them. Unlike RBCs they possesses a nucleus.

(ii) Amoeba: Amoeba can change its shape with the help of pseudopodia (false feet) that are projections of its body and adapt to their environment. During cold days, it wraps itself into a ball.The pseudopodia help the Amoeba to capture its food and move from one place to another.
