Two substances, A and B, initially at different temperatures, come into contact and reach thermal equilibrium. The mass of substance A is 6.15 g, and its initial temperature is 20.5 C. The mass of substance B is 25.2 g, and its initial temperature is 52.7 C. The final temperature of both substances at thermal equilibrium is 46.7 C. If the specific heat capacity of substance B is 1.17 J>g # C, what is the specific heat capacity of substance A?

$$=1.098 \mathrm{J} / \mathrm{g}^{0} \mathrm{C}$$

continuing on with thermodynamics in the world chemistry. We're going to be determining the specific heat capacity valley for our substance that is labeled as a so we've got an abundance of data on DSO. What might be useful is if we start with the equation that will need. So we have massive a multiplied by thes specific heat capacity of eight multiplied by the change in temperature of a sequel toothy, massive B multiplied by the specific heat capacity of be multiplied by the change in temperature off B. So we plug in some values here, so I'll write down the numbers. I'll read out the units just to save a bit of time and space for us. So, um, I say we've got 6.15 grounds multiplied by are unknown, obviously multiplied by a change in temperature, which is 46.7. Subtract 20 points five degrees Celsius. That's equal to negative 25.2 grams multiplied by 1.17 jewels per gram per degrees Celsius, multiplied by a change in temperature. Last 46.7 take away 52 0.7. So we re arranged for our specific heat capacity off a 6176.9 Several jewels divide that by 161.16 grams per degrees Celsius. We get a value off 1.79 Hey, Jules, per grams degrees Celsius is our specific heat capacity off substance faith.
