Answer:
The value is
Explanation:
From the question we are told that
The power output is
The mass of the steel is
The temperature of the water is
The time take is
Generally the quantity of heat energy given out by the electric stove is mathematically represented as
=>
=>
This energy can also be mathematically represented as
Here is the specific heat of stainless steel with value
tex]c_s[/tex] is the specific heat of water with value
m_w is the mass of water which is mathematically represented as
=>
So
converting to
