Specific Heat. What are the building blocks? This concept does not involve building or breaking down of molecules but might involve a mixture of elements.
Heat A Form of Energy Molecules and Motion The motion of molecules produces heat The more motion, the more heat is generated.
1 Physical and Chemical Properties of Water Advanced Environmental Geochemistry – Lecture 3 – Spring 2010.
Thermal Energy. Temperature Measures the “hotness” (higher temperatures) or “coldness” (lower temperatures) Gives very little information on the energy.
Energy Ability to do work Many different forms Conservation of energy (Law) Transformed: example: – Radiant to Thermal – Kinetic to Thermal (friction)
HNRS 227 Lecture 5 and 6 Chapter 4 and Chapter 5 Heat and Temperature Wave Motion and Sound presented by Prof. Geller.
Thermodynamics. Temperature How hot or cold something feels compared to a standard Typically water is our standard Function of kinetic energy
Feeding the World. Human Nutrition Humans need energy to grow, move, and repair our bodies. All humans belong to one species – so our dietary requirements.
Health-Enhancing Behaviors. Exercise Types of Exercise Aerobic Exercise Elevated heart rate and respiration Weight training Resistance important for.
Water Systems. Heat and temperature “hot” – lots of heat energy “cool” – little heat energy Something is cold if it will take away heat from its surroundings.
Stating a Measurement In every measurement there is a Number followed by a Unit from a measuring device.
