If a sample of chloroform is initially at 25°C, what is its final temperature if 1.5 kg of chloroform absorbs 1.0 kilojoules of heat, and the specific heat of chloroform is 960 J/kg C?
Here, we're relating a few things: (1) the mass of the substance, (2) its specific heat, and (3) the temperature change, with the following equation:
Here, we aren't given the temperature change, but we are given the energy absorbed (and hence, a positive sign). Let's translate this first, for an easier calculation
Some quick algebra, and we have:
From here, we'd like to add this quantity to the initial temperature,
