Question

Characteristics of water that make it valuable for fire extinguishment include:

A. low coefficient of friction.
B. a single application method.
C. a greater heat-absorbing capacity than other agents.
D. an ability to change to steam with little energy required.

Answer 1

Water is valuable for fire extinguishment due to its high heat-absorbing capacity, ability to change to steam with little energy required, and low coefficient of friction.

Step-by-step explanation:

Water has several properties that make it valuable for fire extinguishment:

1. High heat-absorbing capacity: Water has a high specific heat capacity, meaning it takes a lot of heat to raise its temperature. This property makes water effective at absorbing heat from a fire and reducing its temperature.
2. Ability to change to steam with little energy required: Water has a high heat of vaporization, which means it requires a significant amount of heat to convert from liquid to steam. This property allows water to absorb large amounts of heat from a fire as it evaporates.
3. Low coefficient of friction: Water has a low coefficient of friction, which helps to spread the water effectively over a fire and enhance its extinguishing capabilities.
