When a solid dissolves in water, heat may be evolved or absorbed. the heat of dissolution (dissolving) can be determined using a coffee cup calorimeter. in the laboratory a general chemistry student finds that when 1.44 g of cuso4(s) are dissolved in 106.40 g of water, the temperature of the solution increases from 24.05 to 25.58 °c. the heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.60 j/°c. based on the student's observation, calculate the enthalpy of dissolution of cuso4(s) in kj/mol. assume the specific heat of the solution is equal to the specific heat of water.

When temperature of a substance increases, of its particles increase resulting in more between particles. real world applications of thermal expansion absolute zero (-273 degrees c) is the lowest possible temperature on the kelvin scale. it is a measure of where a substance has no kinetic energy. heat is a process of the . energy flows spontaneously from a object to a until equilibrium is reached. heat is measured in heat is transferred throughis a method of heat transfer that occurs between particles of matter that are in direct contact with each other. are poor conductors that impede / reduce the rate of heat transfer. is a method of heat transfer that occurs in fluids (non-solids) by means of currents. real world application of convectiona method of heat transfer through electromagnetic waves. when energy moves from one object to another inside a closed system, no energy is or in the system in the transaction. systems will spontaneously move to a state of organized energy or high disorder over time called
