The primary method of heat transfer from the Sun to the Earth is radiation, as it travels through the vacuum of space.

The primary mode of heat transfer from the Sun to the Earth is radiation, as it travels through the vacuum of space.

In a vacuum, there are no particles to conduct or convect heat, so radiation is the only mode of heat transfer.

Convection is the primary mode of heat transfer in liquids and gases due to the movement of the fluid.

Insulation is used primarily to prevent conduction of heat, thereby maintaining the desired temperature inside buildings.

Thermometers work on the principle of expansion of liquid (like mercury) with temperature.

The relationship is given by H = U + PV, where H is enthalpy, U is internal energy, P is pressure, and V is volume.

For an ideal gas, Cp is always greater than Cv because it includes the work done against the atmospheric pressure.

The relationship is Cp = Cv + R for an ideal gas, where R is the gas constant.

For an ideal gas, the relationship is given by Cp = Cv + R, where R is the universal gas constant.

The average kinetic energy of particles in a substance is directly proportional to its temperature.

The temperature of a substance is directly proportional to the average kinetic energy of its particles.

The SI unit of temperature is Kelvin.

The SI unit of thermal conductivity is Watts per meter per Kelvin (W/m·K).

The First Law of Thermodynamics establishes the conservation of energy principle, stating that energy cannot be created or destroyed.

The specific heat capacity at constant volume for a monatomic ideal gas is Cv = 3/2 R.

The specific heat capacity of a substance is defined as the amount of heat required to raise the temperature of a unit mass by 1 degree Celsius.

Specific heat capacity (c) = Q / (m * ΔT) = 500 J / (100 g * 5°C) = 1 J/g°C.

The specific heat capacity of water is approximately 4.18 J/g°C.

The Stefan-Boltzmann law states that the total energy radiated per unit surface area of a black body is proportional to the fourth power of its absolute temperature.

Specific heat capacity is defined as the amount of heat required to raise the temperature of 1 kg of a substance by 1 degree Celsius.

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

Convection is the term used for heat transfer that occurs due to the movement of a fluid.

Radiation is the transfer of heat through electromagnetic waves, such as infrared radiation.

The SI unit of heat is the Joule.

The unit of thermal conductivity is Watts per meter per Kelvin (W/m·K).

The universal gas constant R is 8.314 J/(mol·K).

In an isobaric process, the work done by the gas is given by W = PΔV, where P is the pressure and ΔV is the change in volume.

The work done by a gas during expansion against a constant external pressure is given by W = PΔV, where P is the pressure and ΔV is the change in volume.

The work done by a gas during expansion at constant pressure is given by W = PΔV.
