Does a glass of water evaporate faster with a lid or without?
A glass of water will generally evaporate slower with a lid on compared to without a lid. This is because the lid prevents the water vapor from escaping into the surrounding environment, leading to reduced evaporation.
Is it possible to change the temperature of a glass of water by stirring the water even though the glass is insulated from its surroundings?
No, stirring the water will not change the temperature of the water in an insulated glass. The insulation prevents heat transfer with the surroundings, so internal energy is conserved and stirring only affects the distribution of kinetic energy within the water, but not its overall temperature.
In measuring volume of liquid why is there a need to remove traces of grease in the graduated cylinder?
Grease prevents water contact with the glass cylinder.
A glass is inverted over a basin of water and slowly inserted into the water. however the water does not enter the glass. this experiment proves that water cannot be compressed?
The experiment demonstrates that water cannot enter the inverted glass due to air pressure. As the glass is submerged, the air inside it prevents water from filling the space, creating a seal. This illustrates that liquids, like water, are incompressible under normal conditions, as they cannot be squeezed into the glass while the air pressure remains. Therefore, the inability of water to enter the glass is a result of air pressure rather than a direct proof of water's incompressibility.
Why is glass described as hydrophillic?
Glass is described as hydrophilic because its surface has an affinity for water molecules, allowing water to spread out evenly and form a thin film instead of beading up. This property is due to the presence of hydroxyl groups on the glass surface that attract and bond with water molecules.
Which property allows water to stick to glass?
This is called adherence. It is the force of attraction between the water molecules and the glass molecules.
When you overfill your glass with water and there's a slight bulge at the top of the glass you are witnessing the property of what water?
cohesion
When a glass is placed facing down in a basin of water why don't the water go inside the glass?
The air pressure acting on the water surface prevents it from entering the glass. The pressure of the water pushing against the glass is not enough to overcome the air pressure inside the glass, which keeps the water out.
How do you spell pore as in poor a glass of water?
The correct spelling is "pour"
When water sticks to glass what property of water is being demonstrated?

Why is a ball given in the gauge glass?
incase if boiler gauge glass breaks...this steel ball fits on the tube and it prevents of leakage of water.
What property of water allows a dome of water to form over the edge of a glass when you add more water to a glass that is already full?
Surface Tension
What happened to the water in a glass when turned upside down?
When a glass of water is turned upside down, the water does not fall out due to the presence of air pressure pushing against the water, creating a vacuum inside the glass. This vacuum holds the water in place, creating a seal that prevents the water from spilling out.
When an empty glass is inverted into a tub of water. Why the water does not enter the glass?
The air pressure inside the glass is stronger than the water pressure outside, creating a barrier that prevents the water from entering the glass. This is due to atmospheric pressure pushing down on the surface of the water and keeping it from filling the inverted glass.
What is the above property of water is called?
The above property of water is called anomalus
