Explanation

The energy extracted from the vaporised liquid as evaporation occurs will decrease the temperature of the liquid, resulting in a process known as evaporative cooling.

Explanation

Head is the change in water levels between the hydro intake and the hydro discharge point.

It is a vertical height measured in metres.

Explanation

To find the current flowing through the conductor, you can use Ohm's Law, which states:

$\text{Voltage (V)}=\text{Current (I)}\times \text{Resistance (R)}$

Given that the power (P) of the conductor is $100\text{W}$, and the voltage (V) is $250\text{V}$, you can use the formula:

$\text{Power (P)}=\text{Voltage (V)}\times \text{Current (I)}$

Solve for current (I):

$\text{Current (I)}=\frac{\text{Power (P)}}{\text{Voltage (V)}}$

Substitute the given values:

$\text{Current (I)}=\frac{100\text{W}}{250\text{V}}=0.4\text{A}$

So, the current flowing through the conductor is $0.4\text{A}$.
