To be able to work our the specific heat capacity i had to draw a gradient on the graph and use the value from it: c = energy mass temperature change using the gradientto be able to work out the specific heat capacity the mass must be included which – the value that i worked out for the specific heat capacity of ethanol is 2353jkg- k-this . Where q is the amount of heat needed, m is the mass of the material, c is the specific heat of the material, and δt is the change in temperature from the above equation, the amount of heat needed is proportional to the temperature change, which means more heat will be needed to raise the temperature of the cool water and less heat will be . Introduction the specific heat of any material determines the amount of energy needed to heat 1 kg of substance by 1 degree which is obtained through the equation q = mc∆t where ‘m’ refers to the mass of material, c is the specific. Physical and chemical changes + specific heat essay by rmassena, high school, for example, you can find energy gained/lost, mass, specific heat of a substance . Discussion graph relationship between the atomic mass of metal atoms and the specific heat of a metal 1 pages.
Notes on the atomic weight of particular elements: atomic radius: molar volume: atomic weight: name: autoignition point: specific heat: electronegativity:. Thus, by measuring the specific heat of a new element, its atomic weight could be readily established the specific heat and atomic mass for a series of elements are provided for reference plot the graph of specific heat versus the inverse of atomic mass. C) calculate the specific heat and the atomic mass of the metal answer preview : a) temperature of metal at equilibrium will be same as final temperature of water, because untill there is a temperature difference heat transfer wont stop and changes in temperature will. Conclusions the purpose of this experiment was to find the relationship between a substance’s specific heat and its atomic weight in the lab, the substances with the higher atomic weights had less specific heat.

Essay papers search blog - latest news heat also, be sure you calculate (and show your detailed work) both the specific heat and atomic weight of each metal . Heat of formation of magnesium oxide objetive: to determine the heat formation of mgo (magnesium oxide) using hess’s law, which states the heat within a chemical reaction is independent of the pathway between the initial and final states. What is the relationship between specific heat capacity and atomic mass how are they related follow 2 (specific heat capacity) x (atomic mass) = 3r . In the lab, the substances with the higher atomic weights had less specific heat from this, we can conclude that specific heat and atomic weight have an inverse relationship, meaning as one decreases the other increases.
