We can assume that the specific heat capacity of water is 4.18 J / (g × °C) and the density of water is 1.00 g/mL. qwater = m × c × ΔT m = mass of water = density x volume = 1 x 26 = 26 grams ΔT = T(mix) - T(water) = 38.9 - 25.3 = 13.6 q(water) = 26 x 13.6 x 4.18 q(water) = 1478 Joules SPECIFIC HEAT: qmetal = -205 J = 15.363 g X c X (27.2 - 100.3 C) c = 0.183 J/gC PART2.

Family’s loving pets are being ripped from their grasps because of BSL laws. What’s up with that? BSL means breed specific legislation and it’s laws are made to help protect people and communities from “blacklisted” dogs‚ but does BSL actually do what it’s meant for and really stop dog attacks. Many people are agreeing that breed specific laws are not helping. Here is my opinion on this controversial argument. BSL laws should not exist and do more harm than good‚ not just to the “blacklisted” dogs

Are We Breeding Fear? People tend to believe that the Pit Bull is bred to be aggressive. In fact‚ in many parts of the world there are breed-specific legislations (BSL) that ban certain breeds of dogs all together and Pit Bulls are one of the most commonly banned breeds due to perceived aggressiveness. Surprisingly‚ there is no easy evidence that Pit Bulls are any more naturally aggressive toward humans than any other breed (West).A 20-year study conducted by the Center for Disease Control and

Measuring the energy content of three different food samples by using the change in water temperatures from the heat given off while burning the sample. To verify our results much further — equations‚ such as energy and heat capacity calculations‚ helped us establish on such results. As a result of the experiment
