Which of the following will not affect the rate of evaporation?

Which of the following will not affect the rate of evaporation?

Explanation: The rate of evaporation is depends on some factors like temperature, wind speed, surface area etc. But not on the mixed absolute heavy impurities.

At what temperature does water start evaporating?

212° F

How do you calculate the evaporation rate of water?

I did my own research, and according to The Engineering Toolbox,the formula for the evaporation rate of water is as follows:

1. gh=ΘA(xs−x)
2. gh = amount of evaporated water per hour (kg/h)
3. Θ=(25+19v) = evaporation coefficient (kg/(m2 h))
4. v = velocity of air above the water surface (m/s)
5. A = water surface area (m2)

What is difference between boiling and evaporation?

To summarize, evaporation is slower, occurs only from the surface of the liquid, does not produce bubbles, and leads to cooling. Boiling is faster, can occur throughout the liquid, produces lots of bubbles, and does not result in cooling.

What is the difference between boiling and boiling point?

The boiling point of a liquid is the temperature at which its vapor pressure is equal to the pressure of the gas above it. The normal boiling point of a liquid is the temperature at which its vapor pressure is equal to one atmosphere (760 torr). Microscopic view inside a bubble in boiling water.

What takes place at the melting point?

Melting point, temperature at which the solid and liquid forms of a pure substance can exist in equilibrium. As heat is applied to a solid, its temperature will increase until the melting point is reached. When all the solid has melted, additional heat will raise the temperature of the liquid.

What is melting point and boiling point of water?

At the boiling point, water transitions from its liquid to gas (vapor) state. Increasing the temperature above the boiling point, 212°F (100°C), causes water to change from liquid to gas (water vapor). The melting/freezing and boiling points change with pressure. At sea level, pure water boils at 212 °F (100°C).

What is called melting point?

Melting point is the temperature at which a given solid material changes from a solid state to a liquid, or melts.

What is melting point Class 11?

The melting point is usually defined as the point at which materials changes from a solid to a liquid. The temperature at which solid changes its state to liquid at atmospheric pressure is called the melting point of that liquid. This is the point at which both liquid and solid phase exists at equilibrium.
