Faster-moving particles mean higher temperatures, while slower ones mean lower. Scales like Fahrenheit and Celsius give standardized points for freezing, boiling, and body temperature, allowing easy temperature comparison across different systems.

Heat capacity refers to the energy needed to raise a substance’s temperature, while specific heat capacity measures the energy required to heat 1 gram of a substance by 1°C. Water, with its high specific heat, heats and cools more slowly than metals.

Objects with a high specific heat capacity require a greater change in energy to change their temperature and vice versa for objects with a low specific heat capacity. Measured in units of Joules per Kelvin kilogram, the specific heat capacity of material can be used to find the change in thermal energy when an object undergoes a temperature change.

Specific heat capacity (c) tells us how much heat energy is required to change one unit mass of a substance by one unit of temperature. Specific heat is related to heat (q), the mass of the sample (m), and the change in temperature (∆T) by the equation q=cm∆T.
