Due heating temperature of metal will rise and will be higher
So correct answer is: 1st option
It will be equal to the temperature of metal after heating.
Temperature of surrounding is assumed to be constant as it is very high domain.

How many kilograms of CO2 are released during the combustion of 25.00 gallons of gasoline? Assume gasoline is pure isooctane with a density of 0.6919 g/ml. If the combustion was used to heat 8565L of water from an initial temperature of 11.0C what would be the final temperature of the water assuming 54.00% efficiency in the energy transfer?

Temperature Change and Heat Capacity - Calorimetry- Two substances The quantitative relationship between heat transfer and temperature change is Q = mcAT, where Q is heat transfer, m is the mass of the substance, and AT is the change in temperature. The symbol c stands for specific heat and depends on the material and phase. The specific heat c is the amount of heat necessary to change the temperature of 1.00 kg of mass by 1.00°C....
