An object with a heat capacity of 3. 40×103j∘c absorbs 54. 0 kj of heat, beginning at −25. 0∘c. What will be the final temperature of the object?.

You cannot find the final temperature since the mass of the object is unknown. You can use the calorimetry formula, which is defined to be Q = mcΔT, to find the final temperature only if all, but the change in temperature, variables are given.Calorimetry definitionCalorimetry is mathematically expressed as Q = mcΔT where Q represents the heat energy, m represents the mass, c represents the specific heat capacity and ΔT represents the change in temperature.If you want to find the heat energy of an object, you have to know the mass, the specific heat capacity and the change in temperature of the object. You can't omit any variable from the equation, otherwise it is not the equation of calorimetry.Learn more about calorimetry here: brainly.com/question/8168263#SPJ4
