# Water temperature questions

• neginf
When a pot of water is boiling vigorously, some of it is steam and some of it is water. Does that mean the water that is still liquid has not hit boiling temperature yet or does the change over from liquid to steam take a while, even at boiling temperature?In summary, the transition from liquid to solid or from liquid to steam can take a certain amount of time and energy, even at freezing or boiling temperatures. Additionally, the presence of small bubbles in hot water may not necessarily indicate boiling, as they could be gasses coming out of solution.

1. When a cup of water is in a freezer, for a while, some of it's ice and some of it's liquid.

Does that mean the liquid part has not hit freezing temperature yet or does the changeover from liquid to solid take a while, even at freezing temperature?

2. When a pot of water gets hot enough, small bubbles form.

Is that considered boiling ?

any small bubble is vapor so its probably boiled. and the transition from water to ice does take a certain amount of energy, so it is likely that the water is below freezing but hasn't solidified yet.

EDIT: when I say that it has probably boiled I am talking about the specific bubble not the whole pot.

Do you know what a latent heat is?

Not necessarily. The solubility of gasses in water decreases as temperature increases. Therefore, the small bubbles could actually be gasses (e.g. nitrogen, oxygen) coming out of solution rather than water vapor.

For the rest of the questions, you have to consider that your system may not have had enough time to reach equilibrium.

## 1. What is the ideal water temperature for swimming?

The ideal water temperature for swimming is typically between 78-82 degrees Fahrenheit. This temperature range is comfortable for most people and allows for efficient movement in the water.

## 2. How does water temperature affect marine life?

Water temperature plays a crucial role in the survival and behavior of marine life. Sudden changes in temperature can stress or even kill certain species. Warmer water can also lead to the growth of harmful bacteria and algae, while colder water can reduce oxygen levels and impact the food chain.

## 3. Does water temperature affect the weather?

Yes, water temperature can impact the weather. Warmer ocean temperatures can lead to the formation of tropical storms and hurricanes, while colder water can contribute to the development of polar vortexes and winter storms.

## 4. Can water temperature impact human health?

Yes, extreme water temperatures can have negative effects on human health. Cold water can cause hypothermia and increase the risk of heart attacks, while warm water can lead to dehydration and heat stroke.

## 5. How does water temperature affect plant growth?

Water temperature is a crucial factor in plant growth. Generally, warmer water temperatures can increase the rate of photosynthesis and promote faster growth, while colder water can slow down growth. However, different plants have different temperature preferences, so it is important to research the specific needs of each plant.
