A typical 12-V car battery can deliver about 750,000 C of charge before dying. This is not a lot of charge. As a comparison, calculate the maximum number of kg of water (at 100 degrees Celsius) that could be boiled into steam (at 100 degrees Celsius) using energy from this battery.

Answer:

3.982 kg

Explanation:

The latent heat of vaporization = 540 cal/g

= 5.4 ×10⁵ cal/kg

L = 5.4 ×10⁵ × 4.19

  = 2.26 × 10⁶ J/kg

Q = 12 × 750,000

= 9, 000, 000

= 9 × 10⁶ J

the maximum number of kg of water (at 100 degrees Celsius) that could be boiled into steam (at 100 degrees Celsius) is:

= [tex]\frac{ 9*10^6}{2.26*10^6 }[/tex]

= 3.982 kg
