WebAug 29, 2024 · (CC BY-NC; CK-12) Summary Heat capacity is the amount of heat required to raise the temperature of an object by \(1^\text{o} \text{C}\). The specific heat of a substance is the amount of energy required to raise the temperature of 1 gram of the substance by \(1^\text{o} \text{C}\). WebHeat and temperature are two different but closely related concepts. Note that they have different units: temperature typically has units of degrees Celsius (∘ C ^\circ\text C ∘ C degrees, start text, C, end text) or Kelvin (K \text K K start text, K, end text), and heat has units of energy, Joules (J \text J J start text, J, end text ...
