How much heat is necessary to change 30 grams of water at 40 degrees celsius into water at 60 degrees celsius?
The idea here is to: * Look up the specific heat of water. * Multiply the mass, times the temperature difference, times the specific heat of water. You may need to do some unit conversions first; specifically, if the specific heat is given per kilogram, you can convert the grams to kilograms.
How many minutes does it take for water to get 80 degrees F?
It depends entirely on what the initial temperature and volume of the water is and how much heat is applied.
How much time did it take for the water to reach 100 degrees celsius?
That depends on the amount of water, on how cold it was initially, and on how fast heat energy is supplied.
How much heat is required to change 0.2kg of ice at -5 degrees to water at 5 degrees?
Heat required for this transition is given as the the sum of three heatsheat required for heating the ice from -5 degree Celsius +latent heat(conversion of ice at zero degree to water at zero degrees)+heat required to heat the water from 0 to 5 degree CelsiusHeating of ice=m x s x delta T,where m is the mass ,s is the specific heat of ice=200x0.5x5=500calmelting of ice=mxlatent heat=200x80=16,000calHeating of water=m x s x delta T,where m is the mass ,s is the specific heat of water =200x1x5=1000calTotal heat required=500+16,000+1000=17,500 cal
How much water should a pool lose on an average summer day in the south?
The answer will depend on the South of what? Which country or continent?It will also depend of the exposed surface area of the water in pool.
What causes evaporation besides heat?
Evaporation can also be caused by a decrease in air pressure, which lowers the boiling point of the liquid. Wind can increase the rate of evaporation by removing the water-saturated air from the liquid's surface. Surface area also plays a role, as greater surface area exposed to air will lead to increased evaporation.
What is the relationship between surface area and rate of evaporation?
Evaporation is a process that takes place at the surface of a liquid, therefore the rate of evaporation is directly related to the surface area. Twice as much surface area will give you twice as much evaporation.
What plant has leaves with waxy surfaces to protect themselves from dehydration due to much sunlight?
Such plants tend to store water in swollen leaf cells, and are generally classed as succulents. The waxy leaf surface is to prevent too much evaporation of water due to the heat.
Does higher boiling point evaporate faster?
No, a higher boiling point means that a substance requires more heat to reach its boiling point and evaporate. Therefore, a substance with a higher boiling point would evaporate slower than a substance with a lower boiling point.
How much of the water in the water cycle enters the atmosphere?
Roughly 84% of the water in the water cycle enters the atmosphere through evaporation from the Earth's surface such as oceans, rivers, and lakes.
What does evaporation rate mean?
The evaporation rate refers to the speed at which a substance transitions from liquid to vapor at a given temperature and pressure. It is influenced by factors such as surface area, temperature, humidity, and air flow. A higher evaporation rate indicates faster evaporation.
Is evaporation and condensation the same thing?
Evaporation and condensation are opposite processes. Evaporation is when a liquid turns into a gas due to heat, while condensation is when a gas turns back into a liquid due to cooling.
What is the difference between the process of boiling and evaporation of water?
Boiling is the rapid vaporization of a liquid when it is heated to its boiling point, occurring throughout the liquid. Evaporation is the slow vaporization of a liquid at temperatures below its boiling point, taking place only at the surface of the liquid. Boiling requires more energy than evaporation.
Why does water spilled on a floor evaporate more rapidly than the same amount of water in glass?
Water spilled on a floor evaporates more rapidly than water in a glass because when water is spread out on a larger surface area, more molecules are exposed to the surrounding air, which increases the rate of evaporation. Additionally, the air circulation around the spilled water on the floor is typically better compared to the water in a glass, further enhancing the evaporation process.
If ambient room temperature is a constant 22 degrees celsius how much of a liter of water would evaporate in 12 hours and is the size of the exposed surface area of 1 liter relevant to evaporation?
-- the area of the exposed surface -- the airflow over the exposed surface -- the temperature of the liter of water -- the air pressure at the exposed surface -- the relative humidity of the air in the room -- the transparency of the liter container are all relevant to the rate of evaporation.
If a fan blows into a pan with water will affect how much water evaporates?
Yes, a fan blowing into a pan of water can increase the rate of evaporation. The moving air from the fan helps to remove the water vapor saturated air above the water surface, allowing more water molecules to evaporate from the surface.
what keeps The leaf from losing too much water from evaporation?
The waxy cuticle on the leaf's surface acts as a barrier to prevent excessive water loss through evaporation. Additionally, the stomata, tiny openings on the leaf surface, can open and close to regulate the amount of water vapor released. Lastly, some plants have specialized cells that can store water and help prevent dehydration.
