quick question

I've done an experiment which was to measure a calorimeters heat capacity. I had to predict how long it would take to make the temperature of water raise by 4K (which was 96s). The questions after are asking me for a ''corrected temperature rise'' I don't know what this means? Can anyone help please?

know what Δ_fH and ΔcH mean? I have to calculate ΔcH for combustion of ethanol using Δ_fH values

I've got no clue, I only did GCSE chemistry. I was just hoping that by me posting more people would see it

Using the equation E=t*V^2/R and SI base units, show E is in joules
t = time = s
V^2 = voltage = kg^2 * m^4 * s^-6 * A^-2
R = resistance = kg * m^2 * S^-3 * A^-1
then I put it in the equation and got E=J * A^-1 :/
