Question

When the heating in coil b dissipates 33.3w of power, the potential difference v across coil given by

Answer 1

Answer:

Liquid enters the tube at a constant temperature of 19.5 °C and leaves the tube at

a temperature of 25.5 °C. The mass of liquid flowing through the tube per unit time is m.

Electrical power P is dissipated in the heating coil.

The student changes m and adjusts P until the final temperature of the liquid leaving the tube is 25.5 °C.

The data shown in Fig. 3.2 are obtained.

m / g s-1 P/ W
