10.2 Calorimetry and Thermodynamics

Master calorimetry & thermodynamics! Learn about heat, energy, and the laws that govern them.

_ a measure of the average value of the kinetic energy of the particles in an object. Heat energy Cold energy Temperature Thermal energy that flows from something at a higher temperature to something at a lower temperature is... temperature heat kinetic energy The amount of heat a substance needs to raise the temperature of 1 kg of that substance by 1°C is... moderate heat bonding heat specific heat What is the formula for calculating specific heat? Q = m x ΔT x c J = m x ΔT x c c = m x ΔT x Q The device used to find the specific heat of a material is a--- calorimeter thermometer calculator A _ is a material in which heat flows slowly. thermal conductor thermal insulator thermal capacitor Temperature and kinetic energy are related. The faster the particles move in a solution, the more friction produced, the hotter the solution becomes. So, what is kinetic energy? energy of position energy of motion High temperatures mean that molecules are moving very fast slow A material in which thermal energy is transferred slowly is a conductor. True False A wet shirt is put on a clothesline to dry on a sunny day. The shirt dries because water molecules -- gain heat energy and condense. gain heat energy and evaporate. lose heat energy and condense. lose heat energy and evaporate. Entropy can also be described as chaos and disorder heat energy work The first law of Thermodynamics tells us that the total energy in the universe is always increasing is constant is decreasing The second law of Thermodynamics tells us that entropy is always _ unless we put in work to keep things organized. increasing decreasing the same chaotic and unpredictable
