What scientific term describes the amount of energy it takes to increase the temperature of 1 kg of a substance by 1℃?
Answer (1)
The scientific term that describes the amount of energy required to increase the temperature of 1 kg of a substance by 1°C is called Specific Heat Capacity (or simply Specific Heat).DefinitionSpecific Heat Capacity (c) is the amount of heat energy needed to raise the temperature of 1 kilogram of a substance by 1 degree Celsius (°C) or 1 Kelvin (K).Formula: [tex]Q=mc \triangle T[/tex]Where: = heat energy (Joules, J) = mass of the substance (kg) = specific heat capacity (J/kg·°C)Δ = change in temperature (°C or K)Example Values of Specific Heat CapacityWater: 4184 J/kg·°CIron: 450 J/kg·°CGold: 129 J/kg·°CThis property explains why some materials heat up or cool down faster than others. For example, water has a high specific heat capacity, meaning it takes a lot of energy to change its temperature, which is why oceans help regulate Earth's climate.
