How many kilojoules are released when 8.2 g of water condenses at 100 C and cools to 15 C?
To calculate the total energy released when 8.2 g of water condenses at 100°C and then cools to 15°C, we first find the energy released during condensation and then during cooling. The heat of vaporization of water is approximately 2260 J/g. Thus, for condensation: ( 8.2 , \text{g} \times 2260 , \text{J/g} = 18,572 , \text{J} ) (or 18.57 kJ). Next, we calculate the cooling from 100°C to 15°C using the specific heat capacity of water (4.18 J/g°C): ( 8.2 , \text{g} \times 4.18 , \text{J/g°C} \times (100 - 15) , \text{°C} = 2,775.6 , \text{J} ) (or 2.78 kJ). The total energy released is approximately 21.35 kJ.
What else can I help you with?
What happens as a air mass cools to it's dew point?
Water vapor turns to water droplets causing it to rain.
When water evaporates the heat is absorbed by the vapor?
The water vapor condenses as it cools, and forms clouds. It later returns to the Earth as precipitation.
What part of the water cycle makes clouds?
Condensation
What gas first appears as a colourless gas then when cooled it condenses into a colourless liquid and boils at 100 degrees celccius?
The most probable answer for your your question is pure water.
What is the energy released when steam condenses to water?
The energy released when steam condenses to water is called the latent heat of vaporization. This energy is released in the form of heat as the steam loses its thermal energy and transitions back into liquid water.
What happens when the water vapor rises and cools?
It condenses into liquid.
What happens when a liquid condenses?
I don't think you can condense a liquid, you can evaporate a liquid eg water which turnns into water vapour then when the water vapour gets colder it cools and condenses
What happens to water vapor when it cools then condenses around dust and salt?
When water vapor condenses around dust particles a cloud is formed
What are formed when water vapor cools and condenses high above the earth's surface?
clouds
Does condensation require energy?
Yes, condensation requires energy to change the phase of a substance from gas to liquid. This energy is released when water vapor cools and condenses into liquid water droplets.
What is the byproduct of condensation?
The byproduct of condensation is water vapor. When water vapor cools and condenses, it turns back into liquid water.
Where is water vapor condenses into liquid water?
Water vapor condenses into liquid water primarily in the atmosphere, particularly when it cools to its dew point. This process often occurs in clouds, where rising air cools and the water vapor condenses into tiny droplets. Additionally, condensation can happen on surfaces when warm, moist air comes into contact with cooler surfaces, leading to phenomena like dew or fog.
Do clouds form when water vapor in the atmosphere cools to its dew point?
A dew point is the amount of moisture in the air so as the air cools water condenses and form clouds.
What happens just before water condenses in clouds?
Before water condenses in clouds, warm air rises and cools as it ascends higher into the atmosphere. As the air cools, it reaches its dew point temperature, causing water vapor to condense into tiny water droplets or ice crystals. These droplets then come together to form clouds.
Examples of gas changing into a liquid?
Condensation.
Are clouds produced from condensation?
Yes, as the warm air rises, it cools, condenses and then forms clouds.
Is condensation released or energy is required?
Condensation releases energy. When water vapor cools and condenses into liquid water, it releases latent heat energy, allowing the molecules to come together and form droplets.
