Answer: Option D) Saturated
Explanation:
A solution is said to be saturated when it contains as much solute as it can dissolve at that temperature. Hence, if more solute is added, it will not dissolve.
Thus, a saturated solution has the maximum amount of solute that will dissolve in a solvent.
B)it is endothermic and entropy decreases
Answer:
- <u>1. The direction of heat flow is from your body to the pool or the air.</u>
<u />
- <u>2. You feel the pool feels cooler because your body temperature drops faster in the water than in the air, due to the higher specific heat capacity of water.</u>
Explanation:
The normal temperature of the body is about 98ºF.
<em><u>1. Heat direction</u></em>
The thermal energy always flows from the warmer bodies to the colder bodies. Thus, the heat from your body flows toward the air or the water.
heat flow
98ºF 80ºF
warmer colder
<u><em>2. Why the pool feels cooler than the air?</em></u>
Water has a high specific heat capacity. That makes that, for a given amount of heat, it will change its temperature little.
When your body is in water the heat of your body will flow to the water and while the themperature of the water changes little the temperature of your body changes more, in the same time. This is, the rate of cooling of your body is higher than the rate of cooling of the water.
When you compare what happens in air, since air has a lower specific heat capacity, the rate of cooling of your body is lower than in water.
Then, the temperature of your body will decrease faster in the water than in the air, which is what you interpret (feel) as the pool is cooler than the air.
Answer:
mettaliods
Explanation:
It has the both property of metal and non metal so it is called mettaliod.
