Water has a high surface tension. Hope that is all you needed=) good luck
Formula for heat change: q = mcδtwhere
q = the heat addedm = massc = specific heatδt= (tf - to in absolute temperature)
note: in this case subtracting the final and initial temperature in kelvin or celsius will not make a difference)
we add everything into the formula: δt = t(final) - t(original)
δt = 36.65 - 24.85δt = 11.8° cso the change in temperature is 11.8 degrees
q = 41.11x 4.319 x 11.8
q= 2095.13 heat of combustion of methane.
it shows that burning 41.11g of methane gives of 2095.13 joules of energy
