A scatterplot is used to represent a correlation between two variables. There are two types of correlations: positive and negative. Variables that are positively correlated move in the same direction, while variables that are negatively correlated move in opposite directions.
Thermal energy, or heat, is the energy that comes from the movement of atoms and molecules in a substance. Heat increases with increases in the speed that these particles move. Geothermal energy is the thermal energy in the earth. Motion energy is energy stored in the movement of objects
If energy is absorbed by a particle, its molecular velocity will increase. Temperature is a measure of the average kinetic energy or the amount of heat per particle of a substance. The specific heat of a substance is the energy in joules required to raise the temperature of one gram of a material by one Celsius degree.
