The specific heat capacity of water is 4.18 J/(g*^ C) , while the specific heat of iron is 0.46 J/(g=^ C) . On a hot summer day, which is cooler: pool filled with water, or an iron grate? How is this phenomenon related to their specific heat capacities?

The water will be cooler as it requires more energy to raise its temperature by 1 degree than the iron gate.

The higher the specific heat capacity more cooler it will be.

Explanation:

The specific heat capacity is defined as the amount of energy required to increase the temperature of the substance by 1 degrees. The energy required to increase the temperature wil be given by the formula:

q = mc ΔT

From the equation we can see the if specific heat capacity increases the energy of the substance gets increase. If specific heat capacity is lower then it is obvious to have low energy.

On hot summer day the temperature would be high we can see that metal like iron would be much hotter than water because iron has less value of specific heat capacity hence less energy required to heat it by 1 degree.

It is now clear that iron gate with low specific heat capacity value (0.46 J/g °C) gets heat up early in hot summer day while water having higher specific heat capacity (4.186 J/g°C) will take more time to heat up hence remains cooler compared to iron gate.

1. true.2. true.3. true.4. false.5. true.the concept of darwin's theory of evolution involves the idea that there are limited resources in a given living environment and that the organisms which live within have variations in their genetic make up due to random mating. the ones with beneficial genetic variations can express certain traits which give them an upper hand in surviving and reproducing in the said environment compared to ones who may have a more disadvantageous variation in traits. over time, the organisms with an upper hand will survive and reproduce more frequently and pass on their beneficial genes while the others die. the result is evolution, where we observe (usually, but not always) eventually, phenotypic distinct changes.

The ancestors of plants that lived in water had plenty of water for the young. angiosperms are a group of land plants that evolved a reproductive trait for living on land. this trait protect young plants by allowing them to grow only when water is present and the conditions for healthy development are right. what trait most likely young angiosperms in this way?
