Webthe equations may be rearranged as: QT = m ci ΔTi + m Hf + m cw ΔTw or Q T = m [ (c i ΔT i) + H f + (c w ΔT w )] Where Q = heat in calories, c = specific heat, ΔT = the change in temperature, H f = the heat of fusion, m = the mass, and the subscripts of “i” and “w” are for ice and water respectively. Weban amount of heat directly proportional to the mass. Therefore, the heat ∆Q into the body is ∆Q = mC ∆T = mC (Tf −Ti), Equation 5.2 where m is the mass of the body, and Ti and Tf are the initial and final temperatures, respectively. The constant of proportionality C, called the specific heat, relates the

WebOct 18, 2012 · The equation is Q=m*c*delta t. Q represents heat, usually in calories. m represents the mass of the substance being tested. c represents the specific heat of the substance being tested. delta t represents the change in temperature of the substance (use a calorimeter). Make sure that units are consistant throughout the equation. http://www.glimme.net/bhs/apreview/FR-4-ans.pdf doh staff health form
