Answer:
The temperature of the metal is
Explanation:
From the question we are told that
The mass of the metal is
The specific heat of the metal is
The mass of the oil is
The temperature of the oil is
The specific heat of oil is
The equilibrium temperature is
According to the law of energy conservation
Heat lost by metal = heat gained by the oil
So
The quantity of heat lost by the metal is mathematically represented as
=>
Where the temperature of metal before immersion
The negative sign show heat lost
The quantity of gained t by the metal is mathematically represented as
=>
So
substituting values
=>
