Answer:
1,298 °C was the temperature of the furnace.
Explanation:
Heat lost by platinum will be equal to heat gained by the water
Mass of platinum = 
Specific heat capacity of platinum= 
Initial temperature of the iron = 
Final temperature = 
=T = 10°C
Mass of water= 
Specific heat capacity of water= 
Initial temperature of the water = 
Final temperature of water = =T = 10°C
On substituting all values:
we get, 
= 1,298°C
1,298 °C was the temperature of the furnace.
