WebThe phase change between a liquid and a gas has some similarities to the phase change between a solid and a liquid. At a certain temperature, the particles in a liquid have enough energy to become a gas. The process of a liquid becoming a gas is called boiling (or vapourization), while the process of a gas becoming a liquid is called condensation. WebNov 8, 2024 · We therefore introduce the specific heat capacity, c, which differs from one substance to the next, and which completes the relationship between heat transferred and temperature change: (5.3.3) Q = m c Δ T. The mass is always a positive quantity, and we define the specific heat capacity as a positive value, which means that Q > 0 when Δ T > 0.
