Is the density of water dependent on temperature?
Yes, the density of water changes with temperature. As water is heated, it becomes less dense and expands, causing it to take up more space. Conversely, as water is cooled, it becomes more dense and contracts, taking up less space.
What processes take place in distillation?
In distillation water is boiled to make steam (or heated to near boiling point to be precice) & the resulting vapour is cooled to provide a pure product, be that water or spirit.
After boiling water with sugar heat retention compared to fresh water?
In my experiment, he water with sugar had the most heat retention and cooled slower than the fresh water. I'm not 100% sure why, but I think it is because it is denser, therefore, when it is heated, more particles have been heated. If there are more particles heated, then it will take longer for each particle to cool down than water which has less particles.
When water gets heated what change may take place?
When water is heated a physical change may take place. The water may evaporate and become water vapor, but the chemical makeup of the water (H2O) will not change.
What is the three forms of water?
Solid (Ice), Liquid (Water), and Gas (Water Vapor). Transforming into these is a physical change. Water transforms into ice by being cooled & into water vapor by being heated and evaporating. Ice transform back into water when warmed. It must go through changing into water before becoming a gas. Vapor can transform into water by being cooled. It must become water before transforming into ice.
How does thermal expansion work and what are its effects on materials?
Thermal expansion is the tendency of materials to expand when heated and contract when cooled. This happens because the particles in the material gain energy when heated, causing them to move more and take up more space. The effects of thermal expansion on materials can include changes in size, shape, and volume. This can lead to issues such as warping, cracking, or structural damage in materials exposed to temperature changes.
Why do metals expand when hot and contract when cooled?
When metals are heated, the atoms within the metal vibrate more rapidly, causing them to take up more space and the metal to expand. When the metal is cooled, the atoms vibrate less, allowing them to move closer together, resulting in contraction. This expansion and contraction is due to the changes in the spacing and movement of the atoms within the metal structure.
How is heat involved in changes the phases of water?
When water is heated the http://wiki.answers.com/q7649733.htmlmove faster and faster causing water to boil and become a gas steam. When you take Answers.com away or cool water its molecules slow down and the water freezes or it becomes a solid.http://www.blurtit.com/q1901944.html
A liquid heated beyond a certain temperature becomes a?
Generally a solid. Although one also needs to take pressure in consideration to be exact.
When an electric kettle is switched on it will take a few minutes to heat the water how does the element at the bottom of the kettle heat all of the water?
As water at the bottom is heated, it rises and cold water replaces it. That's heated and the cycle continues until all the water is at the same temperature.
Why is it that when water is frozen it takes more space in a container than when it is water the volume increasing?
Because the when water freezes the atoms contract closely together. When the atoms are heated they are again contracted and take up surface area. The size is the same through the whole process but the amount of surface area changes.
