We see green coloured plastic grass at many places these
days. Space around natural grass feels cooler than space
around the plastic grass. Can you find out why?

Natural grass feels cooler than plastic grass because of evapotranspiration, a process where the grass absorbs moisture and releases it into the air, which cools the surrounding area. Plastic grass, on the other hand, does not have this capability, and it tends to absorb and retain heat, leading to a warmer environment around it.
Here’s a more detailed explanation:
Natural Grass:
Natural grass has a higher moisture content due to its roots absorbing water from the soil. This water evaporates from the leaves and stems, a process called evapotranspiration, which absorbs heat from the air and cools the surrounding area.
Plastic Grass:
Plastic grass is made of synthetic materials like polyethylene or polypropylene, which do not absorb moisture and retain heat instead of releasing it. This means that the area around plastic grass tends to be warmer than the area around natural grass.
