The transfer of heat within a solid material through direct contact between particles or molecules. It involves the transfer of kinetic energy from higher-energy particles to lower-energy particles through molecular collisions.

Radiation as a mode of heat transfer occurs through electromagnetic waves. These waves do indeed exhibit waveforms. Radiation can transfer heat through a vacuum, as it does not rely on the presence of particles or a medium for propagation.

in summer, when a room is air-conditioned, the vapor pressure is generally lower on the inside compared to the outside. This is because air conditioning systems typically remove moisture from the indoor air, reducing the relative humidity and lowering the vapor pressure inside the room.

The saturation point of air is reached when the air contains all the moisture it can hold at a given temperature. At saturation, the air is holding the maximum amount of water vapor it can accommodate, and any further increase in moisture would result in condensation or precipitation.

If the surrounding air is colder than the skin temperature, the body can indeed lose heat through the process of convection and radiation.

If the ambient temperature rises by 10°F (Fahrenheit), it does not necessarily mean that the skin temperature will rise by the same amount. In response to an increase in ambient temperature, the body employs cooling mechanisms to regulate its temperature and prevent overheating. These mechanisms include sweating, increased blood flow to the skin (vasodilation), and enhanced heat dissipation through radiation and convection.

The dry bulb temperature refers to the standard temperature measurement we commonly use, indicating the air temperature without any consideration for moisture content.  The wet bulb temperature is a measurement that takes into account the evaporative cooling effect of moisture in the air. It is determined using a thermometer with a wet cloth or wick wrapped around the bulb. When the air reaches its dew point temperature, the moisture content in the air is at its maximum, and the air is saturated. Further cooling of air results in condensation. At saturation wet bulb temperature aligns with due point temperature. Therefore at the dew point temperature, the dry bulb temperature is equal to the wet bulb temperature.

Wet bulb temperature measurement (thermometer with a wet cloth or wick wrapped around the bulb) takes into account the evaporative cooling effect of moisture in the air. The wet bulb temperature is influenced by factors such as humidity and air movement. Higher humidity reduces the rate of evaporation and results in a smaller difference between the wet bulb temperature and the dry bulb temperature.

A mercury manometer is known for its high precision and accuracy. Mercury is a dense fluid, and the column height can be read with high resolution, allowing for precise pressure measurements.

Psychrometry is indeed the science and practice of studying and analyzing air mixtures and their properties, particularly related to temperature, humidity, and other thermodynamic properties

A Relative Humidity of around 40% to 60% is considered comfortable for most people. RH below 40% lead to discomfort such as dry skin, irritated throat and other issues. RH above 60% can create a humid environment that may feel uncomfortable and promote the growth of mold, mildew, and other moisture-related issues.

The humidity ratio (specific humidity) is typically represented on the Y-axis of a psychrometric chart. It allows for the visualization and analysis of how the humidity ratio changes as other parameters, such as dry bulb temperature or wet bulb temperature, vary along the chart.

The humidity ratio, or specific humidity, represents the mass of water vapor per unit mass of dry air in the air mixture. It is independent of temperature changes, assuming the air mixture is not saturated (100% relative humidity). In other words, as long as the air is not at its saturation point, the humidity ratio will remain constant even if there is a change in temperature.

The average body temperature of a healthy adult is typically around 98.6°F or 37°C

The dry bulb temperature is the temperature measured with a regular thermometer or a dry bulb thermometer. It is the air temperature in a given environment and represents the actual temperature of the air without considering the moisture content.
