Transpiration rates decrease proportionally to the amount of humidity in the air. This is because water diffuses from areas of higher concentration to areas of lower concentration. Thus, when the air spaces between the mesophyll cells in a leaf are saturated with water vapor, and the air outside the leaf is likewise saturated, there is a shallow gradient. A shallow gradient results in a slower transpiration rate. Conversely, if the air outside the leaf is relatively dry, the gradient becomes steep and the rate of transpiration increases.
Humidity affects the rate of transpiration by creating a gradient that impacts the movement of water vapor from the plant to the atmosphere. Higher humidity levels outside the plant reduce the gradient, slowing down transpiration. Conversely, lower humidity levels increase the gradient, leading to a faster rate of transpiration.
As temperature increases, the rate* of evaporation also increases as water molecules move more rapidly at higher temperatures than at low tempratures and also because warm air can hold more water vapour than the cold air. So, on a warm day, the rate of transpiration is hence more than on a cold day.
* It should be noted that the term rate is used to imply: with respect to time.
As the temperature increases, the rate of transpiration increases. This is because if it is warm the plant cells that control the stoma (openings on underside of leaf), make them open wider to allow more water to evaporate. If it is cold, the stoma will remain closed or they will only open a very small way meaning that little water can evaporate.
Edited answer:
The opening and closing of stomata is regulated by sun shine. Temperature inhances the rate of water evaporation from leaves through stomata. Hence increase in transpiration is recorded with increse in temperature.
if the room temprature is hot so the transpiration fastest and if room temprature is cold the transpiration slows

Which factor affects most in transpiration-humidity or light intensity?
Light intensity
What is the rate of transpiration effected by?
The rate of traspiration is effected by light intensity, humidity and wind velocity etc.
What environmental factor has the greatest effect on transpiration?
The environmental factor that has the greatest effect on transpiration is humidity. High humidity levels reduce the rate of transpiration because there is already a lot of moisture in the air, making it harder for water to evaporate from the plant's leaves. Conversely, low humidity levels increase transpiration as the drier air creates a larger gradient for water to move out of the plant.
When transpiration would be minimum?
Transpiration would be minimum when the environmental conditions are cool, humid, and still. This is because high humidity reduces the rate of water loss from the plant leaves, while cool temperatures slow down the metabolic processes that drive transpiration. Calm conditions also prevent the movement of air that can increase evaporation from the leaves.
List environmental factors that effect the rate at which plants transpire?
Environmental factors that affect the rate at which plants transpire include temperature, humidity, wind speed, and light intensity. Higher temperatures generally increase transpiration rates, while higher humidity levels can decrease transpiration. Wind can increase transpiration by removing water-saturated air around the leaf surface, and light intensity can also influence the opening and closing of stomata, affecting transpiration rates.
How does high humidity affect transpiration?
High humidity reduces the rate of transpiration.

Name a factor that affects transpiration rate
What environmental factor has the greatest effect on transpiration?
The environmental factor that has the greatest effect on transpiration is humidity. High humidity levels reduce the rate of transpiration because there is already a lot of moisture in the air, making it harder for water to evaporate from the plant's leaves. Conversely, low humidity levels increase transpiration as the drier air creates a larger gradient for water to move out of the plant.
Does a leaf sweat?
By transpiration. Water molecules pass out of the leaf by diffusion following the concentration gradient from higher concentration to lower concentration. The rate of transpiration varies. Factors that affect the rate of transpiration includes wind speed, light intensity, temperature and humidity
When transpiration is minimum?
humidity
What atmospheric conditions contribute to the highest rate of transpiration?
High temperatures, low humidity, and good air circulation all contribute to the highest rate of transpiration in plants. These conditions increase the rate of evaporation from the stomata on the plant's leaves, leading to more water loss through transpiration.
What atmospheric contribute to the highest rate of transpiration?
Factors such as low humidity, high temperature, and windy conditions contribute to the highest rate of transpiration in plants. Low humidity creates a larger gradient for water to move from the plant to the atmosphere, high temperatures increase the kinetic energy of water molecules, and windy conditions help remove water vapor from around the plant, promoting transpiration.
What factors effect the rate of transpiration?
Factors that affect the rate of transpiration include humidity (higher humidity decreases transpiration), temperature (higher temperatures increase transpiration), wind (increases transpiration by removing water vapor around the leaf), light intensity (increases transpiration by stimulating the opening of stomata), and plant surface area (larger surface area increases transpiration).
Why is the rate of transpiration is not the same all time?
Because sometimes you walk fast and sometimes you walk slowly.
When transpiration would be minimum?
Transpiration would be minimum when the environmental conditions are cool, humid, and still. This is because high humidity reduces the rate of water loss from the plant leaves, while cool temperatures slow down the metabolic processes that drive transpiration. Calm conditions also prevent the movement of air that can increase evaporation from the leaves.
