Study Notes
Cells and Vision
- Rod cells are used for night vision.
- Cone cells are mainly concentrated in the fovea, a central part of the retina.
Cone Cells and Light Sensitivity
- Cone cells are sensitive to red, green, and blue colors of light.
Phase Changes and Energy
- The phase change from solid to liquid or liquid to gas requires an addition of energy.
Specific Heat
- Specific heat (𝑐) is defined as the amount of heat energy required to raise the temperature of 1 gram of a substance by 1°C.
Heat and Temperature Change
- When Q (heat energy) and ΔT (temperature change) are negative, the system is losing heat and its temperature is decreasing.
Specific Heat of Substances
- Water has a higher specific heat than copper.
Phase Definition
- The term 'phase' refers to the state of matter, such as solid, liquid, or gas.
