Question

The heating element in an electric kettle is rated as 2.0 kW. If the water in the kettle is at 100.0 °C, what volume of water will be converted into steam in one minute? The specific latent heat of vaporization of the water is 2,257,000 J/kg and the

3 density of water is 1,000 kg/m .

Answer:The volume is

Explanation:From the question we are told that

The power of the heating element is

The temperature of the water in the kettle is

The time to convert water to steam is t = 1 minute = 60 sec

The specific latent heat of vaporization is

The density of water is

The power of the heating element is mathematically represented as

Where E Energy generated by the heating element in term of heat

substituting values

Now

The latent heat of vaporization is mathematically represented as

Where m is the mass of water converted to steam

So

substituting values

The volume of water converted to steam is mathematically evaluated as

substituting values
