Q = m . C . Δ T q : Heat absorbed m : mass of the sample C : The specific heat of the substance. Δ T : The change in temperature (Final T - initial T) So: q = 15.5 x 4.18 x (50 - 25) = 1619.75 J
Sirius B is primarily made out of a carbon-oxygen mixture that was generated by helium fusion in the progenitor star. The outer atmosphere is now almost pure hydrogen, the element with the lowest mass.
