Pavement.
simply because, the color it self black absorbs heat at a faster and larger rate... you ever notice how on a hot day you can see the tar on your street emit heat , thats because black absorbs the heat.. its the reason why solar panels are black and not white
Thermal insaltion
Iron is a better heat conductor (regardless of color), allowing it to transport more of the heat it has to your body faster.
cold day
On a sunny day, it is usually hotter. Water evaporates faster if the air is hotter.
pavement because its solid and grass isnt solid
The pavement absorbs and releases heat in the day and only releases it at night. Therefor it is cooler at night.
Buildings and pavement tend to absorb energy during the day and release it at night. (They are dark, building have a lot of metal etc.) Trees and grass do not store the heat in a similar fashion This is why cities tend to have slightly higher temperatures than the surrounding countryside.
Meadow; During the day ,the land heats up faster than the sea. At night, the land loses heat faster than the sea does.
A pool with a solar cover will absorb the heat faster during the day and when left on the pool over night it will prevent the loss of heat.
pond
eg. Wet clothes on a washing line dry faster on a hot day that on a cold day. On a hot day the clothes will dry faster the warmer it is. The water in the wet clothes evaporate quicker. Heat helps the process of evaporation because heat spreads out particles
because the pavement traps heat and releases it slowly
In short, I think urban areas have a high temparature due to pollution and high population density.
The desert will heat up faster than a lake. The sand particles have greater thermal conductivity and hence will take up heat faster than water molecules which do not take up heat as easily. It is also the reason why it is cooler at the sea side.
On the ground on the pavement
the water in the sun evaporates faster than in the shade because the heat speeds up the process of evaporation
