THERMAL PROPERTIES OF MATERIALS:

1)One average, which is hotter in the summer, a city far away from any large body of water or a similar city located near a large body of water?

I'm not sure about the reason why, but I think the answer is a city located near a large body of water.
I think this because places such as Israel, California, where they have the ocean, are hotter than places such as London. But I don't know the reason why.

This was a guess...but am I right?

I believe a city located near a large body of water is cooler than one located far from a body of water. First it takes energy to vaporize the water AND there are sea breezes and land breezes that help cool.

Yes, you are correct! On average, a city located near a large body of water tends to be cooler in the summer compared to a city far away from any large body of water.

The reason for this is due to a phenomenon known as the "maritime effect" or "marine effect." Bodies of water, such as oceans or large lakes, have a higher specific heat capacity compared to land. Specific heat capacity refers to the amount of heat energy needed to raise the temperature of a substance.

In the case of cities near large bodies of water, the water acts as a heat sink, absorbing heat energy from the surrounding air. As a result, the temperature near the coastline tends to be cooler as the heat energy is drawn away and stored in the water.

Conversely, cities far away from large bodies of water lack this cooling effect. Without a nearby water source to absorb the excess heat, the land gets hotter during the summer months. This phenomenon is often referred to as the "continental effect" or "continental climate."

Therefore, your observation about cities near large bodies of water being hotter in areas such as Israel or California, and cooler in places like London, is accurate. The presence or absence of a large body of water can significantly influence the temperature and climate of a particular region.
