The heat of vaporization is so high for water because of waters extremely polar structure and the hydrogen bonds water molecules form with each other. It takes increased kinetic energy and increase in temperature to break the hydrogen bonds and allow water molecules to enter the vapor state.
What else can I help you with?
Does Liquid ammonia have a higher heat capacity than liquid water?
No, liquid water has a higher heat capacity than liquid ammonia. Water has a high specific heat capacity due to its hydrogen bonding, which allows it to absorb and release heat more effectively than ammonia.
Which liquid would be most difficult to raise or lower the temp of?
A liquid with a high specific heat capacity, such as water, would be the most difficult to raise or lower the temperature of because it can absorb or release a large amount of heat energy for a given change in temperature. Conversely, a liquid with a low specific heat capacity would be easier to raise or lower the temperature of.
Would fevers run higher or lower if liquid water's specific heat were not so high?
Fevers would run higher if liquid water's specific heat were lower. The amount of energy need to raise our body temperature would be less. Although the body would still develop control mechanisms to regulate the temperature to prevent heat death of the cells.
Three characteristics of water at room temperature?
ANSWER: 1) It is odorless. 2) it is colorless. 3) it is tasteless. This does not apply to water that has touched another surface such as rainwater, groundwater, pondwater, riverwater, tapwater or seawater.
What characteristic of water is not a result of hydrogen bonding?
The high specific heat capacity of water is not a result of hydrogen bonding. Instead, it is due to the extensive hydrogen bonding between water molecules that allows it to absorb and release large amounts of heat without a significant change in temperature.
Which of the following statements about water is false. Liquid water has a low specific heat which makes it a poor coolant 2 Solid water ice is less dense than liquid water or what?
The false statement is that liquid water has a low specific heat, which makes it a poor coolant. In fact, liquid water has a high specific heat capacity, which means it can absorb and release a large amount of heat with only a small change in its own temperature. This property makes water an effective coolant in various applications.
Does Liquid ammonia have a higher heat capacity than liquid water?
No, liquid water has a higher heat capacity than liquid ammonia. Water has a high specific heat capacity due to its hydrogen bonding, which allows it to absorb and release heat more effectively than ammonia.
Which liquid would be most difficult to raise or lower the temp of?
A liquid with a high specific heat capacity, such as water, would be the most difficult to raise or lower the temperature of because it can absorb or release a large amount of heat energy for a given change in temperature. Conversely, a liquid with a low specific heat capacity would be easier to raise or lower the temperature of.
What has high specific heat cohesion and adhesion?
Water has high specific heat, cohesion, and adhesion. Its high specific heat allows it to absorb and release a lot of heat before its temperature changes significantly. Cohesion refers to the attraction between water molecules, which allows it to form surface tension and maintain a stable liquid state. Adhesion is the attraction between water molecules and other substances, which allows water to stick to surfaces like glass or plant tissues.
What liquid would be the most difficult to raise and lower the temperature of?
One with a high heat capacity
Water has a relatively low specific heat?
The specific heat of water is high. An example of an object with low specific heat would be a metal pan. Since specific heat is the energy needed to raise 1g of something 1 degree Celsius, water would have a high specific heat.
Why is water considered as high specific heat and latent heat of vaporization?
The latent heat of vaporization of a liquid is the amount of heat needed to change that liquid when at it's boiling point to a gas. Hydrogen bonds are present between water molecules. These are strong intermolecular forces between the slightly negative oxygen atom in one water molecule and the slightly positive hydrogen atom in another water molecule. These bonds must be broken in order for the water to change from a liquid to a gas and requires a great amount of energy thus explaining water's high latent heat of vaporization.
Would fevers run higher or lower if liquid water's specific heat were not so high?
Fevers would run higher if liquid water's specific heat were lower. The amount of energy need to raise our body temperature would be less. Although the body would still develop control mechanisms to regulate the temperature to prevent heat death of the cells.
What are eight Physical Properties of water?
Water is a liquid at standard temperature and pressure (STP) Water is tasteless Water is odorless Water has a high specific heat. Water in a pure state has a neutral pH Water conducts heat more easily than any liquid except mercury Water has a high surface tension
Three characteristics of water at room temperature?
ANSWER: 1) It is odorless. 2) it is colorless. 3) it is tasteless. This does not apply to water that has touched another surface such as rainwater, groundwater, pondwater, riverwater, tapwater or seawater.
Why Temperature of liquid water rises and falls slowly?
Water has a high specific heat capacity, meaning it can absorb a lot of heat energy before its temperature increases significantly. This property allows water to regulate temperature changes in its surroundings, making it rise and fall slowly. Additionally, water's high heat of vaporization further contributes to its slow temperature changes as it requires a significant amount of energy to change from liquid to vapor.
Why does high specific heat of water make it essential to life?
The high specific heat allows water to act as a heat sink. Water will retain its temperature after absorbing large amount of heat and retain its temperature after losing equally large amount of heat. So water is essential for life.
