I have my Bachelor's and Master's in Chemistry.
I am a full-time secondary school teacher and training towards QTS status and a Master's in Education at present.
I want to help others understand this interesting science with the dedication and expert knowledge that I have been gifted throughout my education.
The propane fuel (C3H8) used in gas barbeques burns according to a thermochemical equation:
If a pork roast must absorb 1.6 * 103 kJ to fully cook, and if only 10% of the heat produced by the barbeque is actually absorbed by the roast, what mass of CO2 is emitted into the atmosphere during the grilling of the pork roast?
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?
