Evaporation occurs at all temperatures, there is no set temperature for evaporation. The temperature would only affect the rate at which the liquid is evaporated - all other things being equal, warmer temperatures encourage faster evaporation. Evaporation will proceed much faster still if the surrounding air is very dry, and in constant motion.
What else can I help you with?
Why is energy required to evaporate a liquid?
Energy is required to evaporate a liquid because the molecules in the liquid need to overcome the intermolecular forces holding them together. This energy is used to break these forces, allowing the molecules to escape into the gas phase. The absorbed energy increases the kinetic energy of the molecules, enabling them to break free from the liquid's surface and become vapor.
Where in the ocean does the water droplet need to be located in order to evaporate?
Evaporation occur at the surface of the ocean.
When gas cylider leak Which gas is evaporate in air from cylinder?
If it is already a gas, it does not need to evaporate.
What is needed to make the water evaporate and leave the salt behind?
funnel sand paper and something to put the water into
How do you use evaporation?
evaporation is when hot water (liquid) rise to form something else Evaporation only occurs at the surface of a liquid and does not need any external heat source. The molecules of liquid spontaneously go into the vapour phase as long as the pressure above the liquid does not exceed what is called the saturation vapor pressure. As a result, the temperature of the liquid decreases. That is the reason you sweat, perspiration is the way by which your body reduces its temperature. Improved By:Bluefzero153627
Does silver evaporate?
Silver does not evaporate at room temperature. It has a high melting point of 961.78°C (1763.2°F), which means it would need to be heated to this temperature in order to evaporate.
How can you change liquid water into a solid or a gas?
To change liquid water into a solid, you need to lower the temperature below 0 degrees Celsius to freeze it. To change liquid water into a gas, you need to raise the temperature above 100 degrees Celsius to evaporate it.
Is sodium a liquid solid or gas?
It is a solid that can be liquefied In order to retrieve it to the solid form you need to allow the liquid to evaporate. It will leave the solid form. It is salt when chlorine is added, creating sodium chloride.
To change a gas to a liquid?
To change a gas to a liquid, you need to lower the temperature of the gas below its boiling point while keeping the pressure constant. This process is known as condensation and it causes the gas particles to slow down and come together to form a liquid.
Why does water need a lot of heat to evaporate?
High temperature favors evaporation but evaporation occur at any temperature.
How do you make liquid argon into gas?
To convert liquid argon into a gas, you simply need to allow it to warm up to its boiling point of -185.8 degrees Celsius (-302.4 degrees Fahrenheit). As the temperature increases, the liquid argon will start to evaporate and turn into gaseous form.
When solid changes to liquid rise in temperature or drop in temperature?
Melting need an increase of the temperature.
How do you quicken evaporation?
Evaporation is a function a substance's vapor pressure. There are two ways to increase the rate of evaporation. If you raise the temperature for most substances it evaporates more quickly. If you give it a larger surface area it will also evaporate more quickly.
Temperature when water changes from a gas to a liquid?
Water can evaporate even at relatively low temperatures, the water only needs to be slightly warmer than it's surroundings to evaporate, so there is no fixed temperature at which water vapour condenses to become water again. Although the above statement is true, water turns to a gas at boiling point of course, yet people tend to forget that when a substance is directly at boiling point (100 degrees Celsius for water) it can either turn into a gas or go from gas back to liquid. just under BP water gas turns completely to liquid while after BP the water liquid becomes a gas.
Why is energy required to evaporate a liquid?
Energy is required to evaporate a liquid because the molecules in the liquid need to overcome the intermolecular forces holding them together. This energy is used to break these forces, allowing the molecules to escape into the gas phase. The absorbed energy increases the kinetic energy of the molecules, enabling them to break free from the liquid's surface and become vapor.
Which forces internal or intermolecular must be broken for methyl alcohol to evaporate?
Intermolecular forces, specifically hydrogen bonding between methyl alcohol molecules, must be overcome for methyl alcohol to evaporate. The hydrogen bonds between molecules need to be disrupted in order for the liquid to transition into a gas during evaporation.
Do they use liquid helium for balloons?
No, in order for helium to be kept as a liquid it would need to be kept at a temperature of -268.93 degrees celsius.This is both highly difficult, and impracticle, therefore helium is stored and dispensed as a gas.
