What form does water take at negative 20 degrees Celsius?
Water is a solid at -20 degrees Celsius
Which must be present in the water cycle for evaporation to take place?
For evaporation to take place there must be some form of heat. This is heat from the sun
What does 85 degrees Celsius equal in Fahrenheit?
85 degrees Celsius is equal to 185 degrees Fahrenheit. You can convert Celsius to Fahrenheit by multiplying the Celsius temperature by 1.8 and then adding 32.
If it is 35 degrees farhrenheit what temperature is it in celsius?
It is 1.67 degrees Celsius. The formula to convert Fahrenheit to Celsius is (Fahrenheit - 32) / 1.8. Applying this formula to 35 degrees Fahrenheit gives us 1.67 degrees Celsius.
Is it true that evaporation and condensation take place when water gains heat energy?
Evaporation is an endothermic process.Condensation is an exothermic process.
Does evaporation cannot take place in the dark?
Yes, evaporation can take place in the dark, in fact evaporation can take place any place and anytime. It is the factors in the environment that helps speed up the process evaporation. Heat, area of exposed surface and agitation (such as stirring). Therefore evaporation can still take place in dark but only slower.
Reactions in cells take place at about?
Reactions in cells typically take place at a temperature of around 37 degrees Celsius, which is the normal body temperature for most organisms. This temperature is optimal for the enzymes and proteins involved in cellular reactions to function efficiently.
Why and how does evaporation take place below zero degree celsius?
Evaporation can occur below zero degrees Celsius through a process called sublimation. In sublimation, a solid transitions directly into a gas without first becoming a liquid. This happens when the air is dry and has very low humidity levels, causing ice or snow to turn directly into water vapor.
What form does water take at negative 20 degrees Celsius?
Water is a solid at -20 degrees Celsius
Is the sun hotter at the surface or the center?
The sun is hotter at its core, where nuclear fusion reactions take place, reaching temperatures of about 15 million degrees Celsius. The surface temperature, called the photosphere, is cooler at around 5,500 degrees Celsius.
Will evaporation take place only when the surrounding temperature is 25 degrees?
Evaporation can occur at any temperature, but it generally happens faster at higher temperatures. Warmer temperatures provide more energy for water molecules to escape into the air as vapor.
How long does it take to freeze 4 cups of water at 17 degrees Celsius?
The time it takes to freeze 4 cups of water at 17 degrees Celsius will depend on factors such as the temperature of the freezer, the container the water is in, and the efficiency of the freezer. In general, it could take several hours to freeze completely.
Which must be present in the water cycle for evaporation to take place?
For evaporation to take place there must be some form of heat. This is heat from the sun
Can evaporation take place in the dark?
Yes, evaporation can take place in the dark. Evaporation is a physical process in which liquid water molecules at the surface gain enough energy to escape into the air as water vapor, regardless of the presence of light.
About how long will it take for 100ml of water to evaporate at normal room temperature (about 23-25 degrees Celsius) not in direct sunlight in a well ventilated room?
The evaporation rate can vary, but approximately it might take around 1-2 days for 100ml of water to evaporate in a well-ventilated room at normal room temperature (about 23-25 degrees Celsius). The factors affecting the rate of evaporation include humidity levels, ventilation, and surface area exposed to the air.
Would the water cycle exist on Earth if the boiling point of water was 200 celsius?
No, because then process of evaporation would not take place. Thus, halting the rest of the process.
How does the evaporation take place in animals?
sweating
