The amount of heat required for a substance to change from one state to another without change in temperature is called:

Latent Heat

• It is the heat required to convert a solid into a liquid or vapour, or a liquid into a vapour, without a change of temperature.
• English scientific expert Joseph Black presented the idea of latent heat.

Specific Heat

• The specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius.
• The specific heat of water is 1 calorie/gram °C = 4.186 joule/gram °C, which is higher than many other common substances.

Convection

• Convection refers to the process by which heat is transferred through the movement of fluids (liquids or gases).
• It plays a crucial role in the Earth’s atmosphere and oceans, influencing weather patterns and climate

Radiation

• Radiation refers to the emission or transmission of energy in the form of waves or particles through space or a material medium.
• The energy can come from various sources, including the sun, nuclear reactions, and even certain devices like X-ray machines.
