Newton’s Law of Cooling. Global Warming and Greenhouse Effect. Calorimetry. 1. Temperature and Energy. 2. We relate energy and temperature by discussing a substance’s heat capacity.. Heat Capacity = heat required to raise temp. of an object by 1. o. C. more heat is required to raise the temp. of a large sample of a substance by 1. Heat. Heat. is energy that flows from a higher-temperature object to a lower-temperature object because of the difference in temperatures.. SI Unit of Heat:. joule (J).. SI unit for heat is the joule, J. Define the term ‘internal energy’.. Explain the differences in the forces of attraction found between particles of a gas compared to particles of a solid.. Explain what is meant by ‘latent heat’.

Nature of science:. Evidence through experimentation: Scientists from the 17th and 18th centuries were working without the knowledge of atomic structure and sometimes developed theories that were later found to be incorrect, such as phlogiston and perpetual motion capabilities. Our current understanding relies on statistical mechanics providing a basis for our use and understanding of energy transfer in science.. Temperature – Macroscopic. At a macroscopic level, temperature is the degree of hotness or coldness of a body as measured by a thermometer. Temperature is a property that determines the direction of . Roygbiv. Parabolic Dish.
