What is the difference between quality & quantity?
Define: Quantity is
- The measurable, countable, or comparable property or aspect of a thing.

Define: Quality is
- An inherent or distinguishing characteristic; a property.

Heat
Define: Heat is
- A form of energy associated with the motion of atoms or molecules and capable of being transmitted through solid and fluid media by conduction, through fluid media by convection, and through empty space by radiation.
Pasted from <http://www.answers.com/topic/heat?cat=health>
Heat is a sum quantity amount measured in calories.
- Add the motion energy of all the particles of the sample.
A calorie is the amount of energy required to change 1 cm3 of water (H2O) by 1°C.
Heat moves by conduction, convection, and radiation from high temperature areas (or objects) to low temperature areas (or objects).
Would a large container or a small container of water heat up faster?
Temperature
Define: Temperature is
- A measure of the average kinetic energy of the particles in a sample of matter, expressed in terms of units or degrees designated on a standard scale.
Pasted from <http://www.answers.com/Temperature?cat=health>
Temperature is a average quality of the motion energy of all particles in a sample, measured in °C (Celsius), °F (Fahrenheit), or K (Kelvin).
- Take the average of the motion energy of the all the particles in a sample.
Temperatures that you should know:
Boiling Point of Water (H2O) | 100°C | 212°F | 373 K |
Freezing / Melting Point of Water (H2O) | 0°C | 32°F | 273 K |
Absolute Zero | -273°C | -460°F | 0 K |
