| Daimler Engine(8) | 1880 Gottlieb Daimler Produces gas emissions harmful to environment |
| Define Work and Energy | Work: Transfer of mechanical energy between two systems Energy: The amount that must be transferred to be able to do work |
| What is the 2nd law of thermodynamics? | Heat must always flow naturally from a hot object to a cold object, never the other way around |
| What was the unexplained observation of newtons cradle and what year was it demonstrated? | 1666 How the ball on the opposite side raises to the same height as the first ball |
| What's the difference between fission and fusion? | Fission: When the nuclei of a atom is split Fusion: When the nuclei of two different atoms combine |
| What do engineers try to reduce when building machines? | Amount of friction between moving parts to reduce waste heat |
| What was the joules experiment? | In 1840 when joules concluded that heat is a form of energy |
| What is vis viva? | Substituted term for energy |
| Open system | Exchanges Matter and energy with its surrounding |
| Closed system | Exchanges only energy with its surroundings |
| Isolated sytem | Cannot exchange matter or energy with its surroundings |
| What is a system? | A set of interconnected parts; Objects involved in doing the transfer of work, or energy. |
| What sources are renewable? | Solar, wind, water, tidal, Biomass, geothermal |
| What sources are non-renewable? | Nuclear, fossil fuels |
| Define potential and kinetic energy | Kinetic: Energy of motion dependant on mass and speed Potential: Stored energy based on position and gravity |
| What is the first law of thermodynamics? | The total energy, including heat, in a systems and its surroundings remains constant |
| List all different forms of energy | Thermal, Mechanical, Potential, Kinetic, Electrical, Electromagnetic, Sound, Nuclear. |
| Define heat | Transfer of energy between systems due to a difference in temperature |
| Define thermodynamics | A science that studies interrelationships of heat, work, and energy. |
| What is the CANDU reactor and what occurs during the release of nuclear energy or radiation? | Canadian Deuterium Uranium Reactor - Nuclear fission occurs |
| What is the law of conservation of energy? | Energy cannot be created or destroyed, only transferred or transformed |
| Define internal combustion engine | Device in which energy is released by burning fuel from inside the machine |
| Define external combustion engine | Device in which combustion of fuels occurs in a chamber outside the machine |
