Formule Q=Mc Delta T. Calculate the heat absorbed when a mass of substance is heated from one temperature to another.calculate the mass of substance that can be heated by a. On lhs use m,c and delta t for the substance an on rhs use m, c and delta t for water.
Do you know what quanties each of the symbols in those formulae represent ? Is the q in formula q=mc (delta t) always positive? Divide both sides by mc q/mc = mcδt/mc q/mc=δt
Delta t = change in temperature.
Heat is expressed in units of joules (j). M is mass, c is the specific heat and delta t is the difference in temperature. This week we learned about using the formula q=mc delta t more in depth. The formula q equals mass delta hf is used when figuring out how much energy is used when a solid is melting into a liquid.the hf means that it is the latent heat of the substance.
