The anomalous behavior of water is due to:
Coastal area has moderate temperature than deserts because:
The presence of water in coastal areas maintains a moderate climate because of:
high density of water
high surface tension of water
high latent heat of vaporization of water
high specific heat capacity of water
H2O has a higher boiling point than HF because:
High density of water is important for marine life because:
What is the benefit of high surface tension of water for insects:
The high viscosity of water is important because:
Water has maximum density at:
Ice as compared with water is:
less dense
more dense
equal dense
not dense
When water cools down below 4oC, it:
evaporates
compressed
contracts
expands
The anomalous expansion of water is due to:
Specific heat is defined as:
The amount of heat energy required to increase the volume of a substance by 1dm3.
The amount of heat energy required to raise the temperature of a substance by by 1oC
The amount of heat energy required to lower the temperature of a substance by by 1oC
The specific heat of water is:
Which of the following is NOT an effect of the anomalous expansion of water?
Water pipes bursting in cold weather
Fish being able to survive in icy lakes
Water vapor rising from the surface of the ocean
Ice floating on water
Water expands when cool below 4oC to 0oC because:
In ice, water molecules are arranged in more regular hexagonal pattern resulting empty space in it structure
In ice, water molecules are arranged in random manner
In ice, water molecules comes close to each other
water evaporates
A lake freezing from the top down because of:
Conduction due to anomalous behavior of water
Convection due to anomalous behavior of water
Radiation due to anomalous behavior of water
Evaporation due to anomalous behavior of water
When water is converted to ice it volume expands about
10%
In colder region, if water pipelines is not properly insulated it bursts because:
The rigidity and tensile strength of thread is due to:
Water exists in liquid state because of:
Which of the following is NOT an example of hydrogen bonding in everyday life?
Coffee sticking to the side of a mug
Ice floating on water
Sugar dissolving in water
Water molecules sticking together to form droplets
Hydrogen bonding is responsible for the high boiling point of water. This is because:
Hydrogen bonds hold water molecules together tightly.
Hydrogen bonds make water molecules more dense.
Hydrogen bonds make water molecules more polar.
Hydrogen bond makes water more viscous
Hydrogen bonding is also important for the structure of many biological molecules, such as DNA and proteins. This is because:
Hydrogen bonding is important in paint application because:
Hydrogen bonding is important in application of detergent because:
It helps the detergent to get dissolve in water then to break down and remove dirt and grease from surfaces.
