Humidity??

Question

Is humidity directly or indirectly proportional to heat? Also please explain as I have my test.

Answer 1

Humidity is directly proportional to heat. Humidity is relative to the temperature. The warmer the air the more moisture it can hold. If the humidity is 100% and the temp is 50 f, then the air is saturated and cannot hold anymore moisture. But is the temperature in the same situation would rise while the moisture remains the same, the % of humidity will lower.

Answer 2

Humidity-

Amount of water vapour in the air. One of the most variable characteristics of the atmosphere, humidity is an important factor in climate and weather: it regulates air temperature by absorbing thermal radiation both from the Sun and the Earth; it is directly proportional to the latent energy available for the generation of storms; and it is the ultimate source of all forms of condensation and precipitation. Humidity varies because the water-holding capacity of air is determined by temperature. When a volume of air at a given temperature holds the maximum amount of water vapour possible, the air is said to be saturated. Relative humidity is the water-vapour content of the air relative to its content at saturation. Saturated air has a relative humidity of 100%; near the Earth the relative humidity rarely falls below 30%. -

Answer 3

The amount of water that can be absorbed in air is determined by two variables: temperature, and pressure. Both variables directly and positively relate to humidity. Humidity is the amount of water in the air. Relative Humidity is the measurement (a ratio) of how much water the air could absorb at a given temperature and pressure. As temperature goes up, air can absorb more water. As pressure goes up, the energy state of H2O goes up as well. That is why there is liquid water under a glacier. Sure, it is below freezing - at normal pressures. But at the pressure provided by all the weight of ice above, the ice turns liquid.
Water (H2O) commonly has 3 states: ice, liquid water, and water vapor. Each kind of state has more energy than the previous.

Humidity is related to the state of water. Usually we are talking about the point at which water changes between liquid water and water vapor. This is called the 'dew point.' If you increase the temperature to liquid water it will turn to water vapor. So if you heat the air - that has a given amount of H2O in it - it will be able to accept more H2O if there is some available. If you lower the air temperature, then some of the water vapor will change state to liquid water. Relative Humidity is the measurement (a ratio) of how much water there is IN THE AIR compared to how much water the air COULD HAVE at that temperature. It is written as a %

If you have a situation where you have 100% humidity, and increase the air temperature, the amount of H2O in the air stays the same, but the amount of H2O that the air CAN HAVE at the higher temperature increases. So, the relative humidity is then LESS than 100%.

;-D Study the link. They do a really good job of explaining it!

Answer 4

Relative humidity is inversely proportional to heat.

As air gets warmer it can hold more water. Therefore, the same absolute amount of water will be a lower percentage of the total water that the air can hold.

Answer 5

Humidity is indirectly proportional to heat because humidity has moisture and when you increase the humidity level the place's moisture level increases and the heat level decreases.

Answer 6

Humidity is indirectly proportional to heat.The both facrtors are not connected in any way.Good luck for the Test!

Answer 7

Humidity is the amount of water vapor in an air sample. There are three different ways to measure humidity: absolute humidity, relative humidity, and specific humidity. Relative humidity is the most frequently encountered measurement of humidity because it is regularly used in weather forecasts. It’s an important part of weather reports because it indicates the likelihood of precipitation, dew, or fog. Higher relative humidity also makes it feel hotter outside in the summer because it reduces the effectiveness of sweating to cool the body by preventing the evaporation of perspiration from the skin. This effect is calculated in a heat index table. The warmer the air the more water it can hold. This is true because the space between the air molecules expands. That increase maximum humidity.


Absolute humidity refers to the mass of water in a particular volume of air. Absolute humidity is expressed as the number of kilograms of water vapor per cubic meter of air. Imagine a cube of air that is one meter wide, one meter high, and one meter deep. If we could “squeeze” all the water out of that cube of air into a container, we could weigh the container and see how many kilograms of water it contains. The amount of vapor in that cube of air is the absolute humidity of that cubic meter of air. More technically: mw, per cubic meter of air, va .


As such, its value changes as the air pressure changes. This is very inconvenient for chemical engineering calculations, e.g. for dryers, where temperature can vary considerably. As a result, absolute humidity is generally defined in chemical engineering as mass of water vapour per unit mass of dry air, also known as the mixing ratio (see below), which is much more rigorous for heat and mass balance calculations. Mass of water per unit volume would then be defined as volumetric humidity. Because of the potential confusion, British Standard BS 1339 (revised 2002) suggests avoiding the term "absolute humidity". Units should always be carefully checked. Most humidity charts are given in g/kg or kg/kg.
