Radiation involves the transfer of energy through electromagnetic waves, which can travel through a vacuum.

The Kelvin is the base unit of thermodynamic temperature in the International System of Units (SI).

Convection is the heat transfer mechanism where the actual movement of fluid molecules occurs due to density differences.

Absolute zero (0 K) is defined as -273.15 degrees Celsius.

Conduction is the transfer of heat between substances that are in direct contact with each other without mass transfer.

The vacuum between the walls eliminates conduction and convection, and the reflective silvered surfaces minimize radiation.

Invar is a nickel-iron alloy notable for its uniquely low coefficient of thermal expansion.

Black surfaces have the highest emissivity and absorptivity for thermal radiation.

Latent heat is the energy absorbed or released during a phase change, and the temperature remains constant during this process.

Specific heat capacity is defined as the amount of heat energy required to raise the temperature of a unit mass of a substance by one degree Celsius or Kelvin.

The Kelvin scale is an absolute thermodynamic temperature scale because it starts at absolute zero, where all thermal motion theoretically ceases.

According to Fourier's Law of heat conduction, the rate of heat flow is inversely proportional to the thickness of the material.

A bimetallic strip consists of two different metals bonded together, which expand at different rates when heated, causing the strip to bend.

Heat is a form of energy; therefore, its SI unit is the Joule.

Water exhibits anomalous expansion and achieves its maximum density at 4 degrees Celsius.

Sea breeze occurs due to the convection currents created by the temperature difference between land and sea.

A calorimeter is a device used in calorimetry to measure the heat of chemical reactions or physical changes.

Thermal radiation consists of electromagnetic waves, which can travel through a vacuum and propagate at the speed of light.

The first law of thermodynamics is essentially the law of conservation of energy applied to thermodynamic systems.
