temperatuurierinevuseks
Temperatuurierinevus, or in translative form temperatuurierinevuseks, refers to the difference in temperature between two bodies or points. It is commonly represented by ΔT = T2 − T1, where T1 and T2 are temperatures. A positive ΔT indicates that T2 is warmer than T1, while a negative ΔT means the opposite. The magnitude |ΔT| expresses how large the temperature difference is. For practical purposes, temperature differences are measured in kelvin (K) or degrees Celsius (°C), and 1 K equals 1 °C for differences, allowing ΔT to be expressed in either unit as long as the units are consistent.
The temperature difference is the driving force behind heat transfer. In conduction through a solid, the approximate
Measurement of temperature difference relies on sensors such as thermocouples or RTDs placed at appropriate locations
