What is the relative humidity if the dry-bulb temperature is 26°C and the wet-bulb temperature is 18°C?

Answers

Answer:

The amount of moisture air can hold is dependent on its temperature and pressure. The warmer the air the greater the quantity of water vapour it can contain. The air temperature is measured with a normal thermometer this is the Dry-Bulb reading. The actual amount of moisture known as the mixing ratio is measured in grams of water per kilogram of dry air. When air at a certain temperature is saturated it cannot hold any more moisture. The relative humidity of the air is the ratio of the actual amount of moisture in the air to the fully saturated amount.

We can use evaporation to measure the amount of moisture in the air. A wet cloth is placed over the bulb of a thermometer and then air is blown over the cloth causing the water to evaporate. Since evaporation takes up heat, the thermometer will cool to a lower temperature than a thermometer with a dry bulb at the same time and place. The depression in Wet-Bulb temperature allows the humidity to be calculated. If the air is fully saturated (100% relative humidity) the water cannot evaporate, so both the wet and dry bulb temperatures are the same. If the dry and wet bulb temperatures are set to the same value the calculator will show the saturation mixing ratio the amount of water in saturated air at that temperature.

If partly saturated air is cooled without changing its pressure or amount of water vapour, a point is reached when it becomes saturated. The moisture will be given up as dew or ice crystals. This temperature is the Dew Point. This is why condensation will form on a bottle of cold beer, as the air in the vicinity of the bottle is cooled below its dew point. Meteorological reports usually quote the temperature and dew point as well as the station pressure. Moisture content and relative humidity can be calculated from these figures.

The Psychrometer is the name of a device containing both a wet and dry bulb thermometer. This can be a fixed device for meteorology or a handheld sling psychrometer that is often used in air conditioning applications.

Explanation:

The relative humidity if the dry-bulb temperature is 26°C and the wet-bulb temperature is 18°C is 45.1%.

Psychrometer:

It is a device that use to calculate the relative humidity and dew. It has two thermometer, one measures the dry temperature while another measures the wet-temperature.

Given here,

Dry-bulb temperature is 26°C

Wet-bulb temperature is 18°C

The difference between temperature of wet and dry bulb is

= 26 - 18 = 8°C

Now compare the temperature difference to the chart given in the

Therefore, the relative humidity if the dry-bulb temperature is 26°C and the wet-bulb temperature is 18°C is 45.1%.

a recipe calls for 1 cup of sugar and 1/2 cup of flour.Zoe uses 1 cup of salt and 1/2 cup of flour.
which kind of mutation is best modeled by zoes version of the recipe​

Answers

Answer:

Substitution

Explanation:

Given the information in the question substitution seems like the most appropriate answer. Zoe used 1 cup of slat rather than 1 cup of sugar, she substituted sugar for salt.

Insertion is wrong because Zoe did not add another ingredient, there is still only 2 ingredients.

Transition is wrong because, given the information, because the state(liquid or solid) of the ingredients has not changed. Zoe is still use dry ingredients per say.

And beneficial also seems to be wrong because we don't know if using salt instead was beneficial to the recipe or to Zoe.

Answers

Answer:

The graph represents the distance a car travels over time while on the highway. Which statement about the car's trip is accurate?
A)
The car does not move over time.
B)
The car travels at a constant velocity.
The car's velocity increases constantly over time.
D)
The car's velocity decreases constantly over time.

Answers

Answer:

B

Explanation:

The chart is going up and up which means the car goes up and up in speed and velocity and is very consistant

The statement that is accurate regarding the car trip is that it travels at a constant velocity. The correct option is B.

What is velocity?

Velocity is the pace and direction of an object's movement, whereas speed is the time rate at which an object is travelling along a path. In other words, velocity is a vector, whereas speed is a scalar value.

The rate of change of displacement is known as velocity. The rate at which velocity changes is called acceleration.

Due to the fact that it includes both magnitude and direction, velocity is a vector quantity. As the rate at which velocity changes, acceleration is likewise a vector quantity.

An object must move at a consistent speed and direction in order to have a constant velocity.

The object can only move in a straight line if the direction is constant. So, motion in a straight line at a constant speed is defined as having a constant velocity.

Thus, the correct option is B.

Adaptation is the evolutionary process whereby an organism becomes better able to live in its habitat or habitats. 2. Adaptedness is the state of being adapted: the degree to which an organism is able to live and reproduce in a given set of habitats.

On the western peninsula, the changing climate means different weather is turning sheets of snow and ice into a land of rain and mud. Older penguins are equipped with waterproof layers of feathers allowing them to move swiftly in the water, and also allowing them to stay warm on land.

Carrying capacity can be defined as a species' average population size in a particular habitat. The species population size is limited by environmental factors like adequate food, shelter, water, and mates. If these needs are not met, the population will decrease until the resource rebounds.

6.Natural selection and selective breeding can both cause changes in animals and plants. The difference between the two is that natural selection happens naturally, but selective breeding only occurs when humans intervene. For this reason selective breeding is sometimes called artificial selection.
