Question

3. 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 1

Answer:

Explanation:

Energy = volt x charge

= 12 x 750000 J

= 9000,000 J

Latent heat of vaporisation

= 2260000 J / kg

kg of water vaporised

= 9000,000 / 2260000

= 3.982 kg .
