The blade of a hoe feel colder to touch in the morning than the wooden handle because the
handle is a better conductor of heat than blade
handle contains stored energy in form of heat
blade is a better conductor of heat than the handle
blade is placed at a lower temperature than the heat
Explication
The metal blade transfers heat away from your skin more effectively than the wooden handle. When you touch the blade, it rapidly absorbs heat from your hand, causing it to feel colder. In contrast, the wooden handle, which is a less effective conductor of heat, doesn't draw heat away as quickly, making it feel warmer in comparison.
