What is needed to make the water evaporate and leave the salt behind?
funnel sand paper and something to put the water into
During a strenuous workout an athlete generates 2000 kJ of heat energy What mass of water would have to evaporate from the athletes skin to dissipate this much heat?
To calculate the mass of water that would need to evaporate to dissipate 2000 kJ of heat, we need to use the heat of vaporization of water, which is 2260 J/g. By converting the energy to joules and dividing by the heat of vaporization, we find that approximately 884 grams (0.88 kg) of water would need to evaporate from the athlete's skin.
Do you need to add or subtract heat make a solid into gas?
Add heat.
When gas cylider leak Which gas is evaporate in air from cylinder?
If it is already a gas, it does not need to evaporate.
Can water evaporate at night?
Yes, water can evaporate at night. The rate of evaporation may be slower due to cooler temperatures and reduced sunlight, but it can still occur if the conditions are right.

When do you need a vaporizer?
when u need something to evaporate really quickly
What part does heat play in evaporation?
heat plays a big part in evaporation by making it occur. we need heat for evaporation so water can evaporate
What part does evaporation play in?

Why is condensing an example of a reversible change?
Because all you need to do is heat the condensate up and it will evaporate again.
Why does water need a lot of heat to evaporate?
High temperature favors evaporation but evaporation occur at any temperature.
How close will a planet have to be to the sun to make water evaporate?
it doesnt need to be that close but not that far ehtier.
How much sweat would have to evaporate per hour to remove the same amount of heat a light bulb produces in an hour?
To remove the same amount of heat as a light bulb in an hour (about 60 watts), approximately 200 ml of sweat would need to evaporate per hour. This calculation is based on the heat of vaporization of sweat and the rate of heat production by a light bulb.
When do you need a Bunsen burner?
To heat something up
Does water need sunlight to evaporate?
No, water does not need sunlight to evaporate. The primary factor that drives evaporation is heat energy, which can come from various sources, not just sunlight. Evaporation occurs when water molecules gain enough energy to escape from the liquid and enter the air as a gas.
What three things are needed to make something burn?
To make something burn, you need fuel (such as paper or wood), oxygen (from the air), and heat (a source of ignition like a match or a spark). These three components make up the fire triangle, and without any one of them, combustion cannot occur.
Does oxygen make something burn?
Oxygen itself does not cause something to burn, but it is necessary for combustion to occur. When oxygen is present, it allows fuel to react with heat, resulting in a chemical reaction that releases energy in the form of heat and light.
