Question

What is temperature? How is it measured?​

Answer 1

We are used to expressing temperature with degrees Fahrenheit (F). Scientists often use degrees Celsius (C), but the Kelvin (K) is the SI unit for temperature. Thermometers can measure temperature because of thermal expansion. Thermal expansion is the increase in volume of a substance due to an increase in temperature...

Most scientists measure temperature using the Celsius scale and thermodynamic temperature using the Kelvin scale, which is the Celsius scale offset so that its null point is 0 K = −273.15 °C, or absolute zero.
