Heat is a form of energy transferred from a hotter body to a cooler one, leading to temperature or phase changes in substances. The chapter explores specific heat capacity, latent heat, and sensible heat, detailing their formulas and applications. It also discusses the methods of heat transfer—conduction, convection, and radiation—each playing a vital role in thermal dynamics.

Heat is a form of energy transferred from a hotter body to a cooler one, leading to temperature or phase changes in substances. The chapter explores specific heat capacity, latent heat, and sensible heat, detailing their formulas and applications. It also discusses the methods of heat transfer—conduction, convection, and radiation—each playing a vital role in thermal dynamics.
Heat is energy transferred due to temperature differences and can cause temperature or phase changes in substances.
Specific heat capacity is the amount of heat required to change the temperature of a unit mass by 1°C.
Latent heat refers to the heat required to change the phase of a substance without changing its temperature.
Sensible heat leads to temperature changes, while latent heat is associated with phase changes.
Heat transfer occurs through conduction, convection, and radiation, each with different characteristics and applications.
A form of energy that flows from a body at a higher temperature to a body at a lower temperature.
The amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius.
The heat required to change the state of a substance without changing its temperature.
The heat that causes a change in temperature of a substance without a phase change.
The transfer of heat through a substance without the movement of the substance itself.
The transfer of heat in a fluid through the movement of the fluid itself.
The transfer of heat through electromagnetic waves, requiring no medium.
The amount of heat required to raise the temperature of an object by 1°C or 1 K.
