Since it can be obtained in very high purity, benzoic acid is one of the classic materials used for determining the heat capacity of bomb calorimeters. the heat of combustion of benzoic acid, hc7h5o2 is -3227 kj mol-1. when 2.85 g of hc7h5o2 (molar mass = 122.12 g/mol) was burned in a bomb calorimeter, the temperature of the calorimeter changed from 24.05 ºc to 29.19 ºc. what is the heat capacity of the calorimeter in units of kj/ºc?

Work out sian speed for the first 30 minutes of her journey. give your answer in km/h.

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
