Specific heat capacity of polystyrene

WebOct 8, 2024 · A sample of polystyrene, which has a specific heat capacity of 1.880 J*g^-1 * C^-1, is put into a calorimeter that contains 300.0 g of water. The polystyrene sample starts off at 88.6 C and the temperature of the water starts off at 23.0 C. When the temperature of the water stops changing it's 28.2. The pressure remains constant at 1 atm. WebOct 27, 2014 · Styrofoam absorbs more heat per gram than steel, but the steel calorimeter is probably heavier. With a fast reaction there is the additional fact that the styrofoam calorimeter probably never comes up to the full temperature of the reaction before you quit recording temperatures.
