Answer:
The normal pattern for most compounds is that as the temperature of the liquid increases, the density decreases as the molecules spread out from each other. ... The ice structure takes up more volume than the liquid water molecules, hence ice is less dense than liquid water.
Water has the property of having a high specific heat. This trait has a great influence on maintaining homeostasis within the body. Which of the following accurately explains what it means to have a high specific heat?
Answer:
The correct answer is - Water efficiently absorbs and retains heat.
Explanation:
High specific heat is water's capacity to gradually warm-up and cool down. This permits water to help keep up homeostasis in the human body. It is the amount of heat needed to increase the temperature of 1 gram of a particular substance or solution 1 degree Celsius.
High specific heat is significant on the grounds that it helps keeps up homeostasis in the body which is significant, and it likewise helps in managing or regulating temperatures. It keeps up homeostasis in the body which is significant, and it likewise manages temperatures.

What do you think should be done about the ecological footprint of developed nations, if anything? State your opinion and back up your opinion using at least seven complete sentences.
Answer:
The size of an individual's Ecological Footprint relies upon advancement level and economical position, and to some degree on the decisions, people make on what they eat, what items they buy, and how they travel.
Be that as it may, choices embraced by governments and organizations affect the Ecological Footprint as well. For instance, people for the most part have no immediate power over the size of the developed land impression. The equivalent is valid for the manner by which a nation creates its power or the force of its agrarian creation.

Because if I put hot water in a cup and poured salt into that same cup the salt is going to dissolve into the water, Because the water melts the salt.
Once the teeth start grinding food,
Blank is produced to make food moist and slippery.
Answer:
Saliva is produced
Explanation:
Think about salivary glands.
Once the teeth begin to grind the food, saliva is produced which is a transparent liquid produced by the many glands of the mouth to make the food moist and slippery.
What is Saliva?Saliva is described as a transparent liquid produced by several glands in the mouth that is vital to one's health. Water makes up the vast majority of it. Saliva contains important components that aid in the digestion of food and repair of teeth.
Saliva is produced by the salivary glands that are found in each cheek, at the bottom of our mouth and near our front teeth, all of which are located near the jawbone. There are six primary salivary glands and hundreds of minor salivary glands in the human body.
Thus, saliva is produced which is a transparent liquid produced by the many glands of the mouth to make the food moist and slippery.

Because of hydrogen bonds between water molecules, it takes a significant amount of heat energy to make water change temperature. The amount of heat needed to make water change temperature by one degree Celsius is known as the specific heat. This number is much larger for water than it is for most other substances. It also takes a large amount of heat energy to change water from a liquid to a gas. This energy is known as the heat of vaporization. Put a drop of water and a drop of rubbing alcohol on a piece of wax paper. Which drop evaporates first? Explain your results. Make sure that you discuss the role of hydrogen bonds in your results.
Answer:
The drop of rubbing alcohol will evaporate first.
Explanation:
According to the question, HEAT OF VAPORIZATION is the amount of heat energy it takes to change a substance from its liquid state to its gaseous state. Water, as a substance, requires a high amount of this heat of vaporization for its evaporation to occur.
This property is attributed to the HYDROGEN BONDING that forms between water molecules. It takes a high amount of heat energy (heat of vaporization) to break this bond. The hydrogen bonds holds liquid water molecules tightly to one another.
Hence, a drop of water will evaporate slower than a drop of rubbing alcohol, which has a weaker hydrogen bonding between its molecules.
