Food cooks faster in a pressure cooker because the air pressure increases, which increases the boiling point of water. This higher boiling point allows the food to cook at a higher temperature, speeding up the cooking process.

If there is a sudden increase in temperature at a place, the relative humidity decreases. As temperature rises, the air’s capacity to hold moisture increases, causing the relative humidity to drop unless additional moisture is added to the air.
300 K is equal to 27 °C. To convert from Kelvin to Celsius, subtract 273.15 from the temperature in Kelvin. Therefore, 300 K – 273.15 = 26.85 °C, which is approximately 27 °C.
The heat required to convert a substance from liquid to gas without any temperature change is called latent heat of vaporization. This process occurs at the substance’s boiling point, where the liquid absorbs energy to overcome intermolecular forces and change ...
A black body can absorb radiation from all wavelengths. As a theoretical concept, a black body absorbs all radiation incident upon it, regardless of the wavelength. This characteristic makes it an ideal absorber and emitter of radiation, which forms the ...
During the winter season, we feel colder due to clear weather. Clear skies allow more heat to radiate away from the Earth’s surface into space, resulting in colder temperatures at ground level. This lack of cloud cover reduces the insulation ...
Absolute humidity is expressed in grams per cubic meter of air. Absolute humidity refers to the actual amount of water vapor present in a given volume of air and is typically measured in grams per cubic meter (g/m³), making option ...
The water remains cold in the pitcher due to the process of evaporation. As water evaporates from the surface of the pitcher, it absorbs heat energy from the surroundings, including the remaining water, cooling it down.
The synchronizing satellite rotates around the Earth in a West to East direction. This rotation synchronizes with the Earth’s rotation, facilitating stable positioning relative to a point on the Earth’s surface. This alignment is essential for functions such as communication ...
The function of the ball bearing in the wheel is to convert static friction into kinetic friction. This conversion allows for smoother rotation by reducing resistance between moving parts. Ball bearings facilitate efficient motion and are crucial components in various ...
